In order to calculate the **speed**, wavelength, or **frequency** of a wave when you know two of the three quantities, you can use the **wave equation**: wave speed (v) = wavelength (λ) x **frequency (f).**

To calculate a wave's speed, **wavelength**, or frequency, you can use the wave equation:

**wave speed (v)** = wavelength (λ) x **frequency (f)**

If you know two of the three quantities, you can rearrange the equation to solve for the third quantity. For example:

- To calculate the wave speed, if you know the wavelength and frequency, you can simply multiply them together: v = λ x f.

- To calculate the wavelength, if you know the wave speed and frequency, you can rearrange the equation to solve for λ: λ = v / f.

- To calculate the frequency, if you know the wave speed and wavelength, you can rearrange the equation to solve for f: f = v / λ.

By using the wave equation, you can easily calculate any of these quantities if you know the other two.This equation allows you to interrelate the speed, wavelength, and frequency of a wave. By knowing two of these quantities, you can determine the value of the third quantity using the equation.

An inclined plane 60% efficiency is used to raise a load of 6000N through alight of 6m. While sliding 20m along the incline find the effort in the system?

### Answers

The effort required to slide the load 20m along the **inclined plane** is 1080** **Newtons**.**

In this case, the inclined plane has an efficiency of 60%. **Efficiency** is calculated as the ratio of useful output work to the total input work. Since the efficiency is given, we can use it to determine the input work. The input work is the product of the effort (force) applied to the inclined plane and the **distance **over which it is applied. In this scenario, the load being raised has a weight of 6000N, and it is being raised through a height of 6m. The input work required to raise the load is given by the formula: input work = load * height = 6000N * 6m = 36,000 N·m.

Now, to find the effort in the system while sliding 20m along the incline, we need to consider the output work. The output work is the product of the effort (force) and the distance over which it is applied. Since the efficiency of the inclined plane is 60%, it means that the output work is 60% of the input work. Therefore, the output **work **is 0.60 * 36,000 N·m = 21,600 N·m.Given that the load is **sliding **20m along the incline, we can divide the output work by this distance to find the effort. Hence, the effort in the system is 21,600 N·m / 20m = 1080 N.

What is the hydronium ion concentration in a solution of HCl that has a pH of 4. 65? × 10n M n = What is the hydroxide ion concentration in a solution of NH3 with a pOH of 4. 65? × 10n M n =.

### Answers

The hydronium **ion concentration **in the HCl solution with a pH of 4.65 is approximately 2.2 x 10⁻⁵ M. On the other hand, the hydroxide ion concentration in the NH₃ solution is approximately ≈ 2.2 x 10⁻⁵ M

How to calculate ion concentrations from pH or pOH?

To calculate the hydronium ion (H3O+) concentration in a solution of HCl with a pH of 4.65, you can use the formula: pH = -log [H3O+].

First, you'll need to rearrange the formula to solve for [H3O+]. You can do this by taking the inverse logarithm (antilog) of both sides:

[H3O+] = 10^(-pH)

Now, plug in the given pH value of 4.65:

[H3O+] = 10^(-4.65)

Calculating the value, you get:

[H3O+] ≈ 2.2 x 10⁻⁵ M

So, the **hydronium ion** concentration in the HCl solution with a pH of 4.65 is approximately 2.2 x 10⁻⁵ M.

The pOH is defined as the negative logarithm (base 10) of the hydroxide ion concentration ([OH-]).

The relationship between pOH and [OH-] is as follows:

pOH = -log[OH-]

To find [OH-], we rearrange the equation:

[OH-] = 10^(-pOH)

Given a pOH of 4.65, we can calculate the hydroxide ion concentration as follows:

[OH-] = 10^(-4.65)

[OH-] ≈ 2.2 x 10⁻⁵ M

The **hydroxide ion** concentration in the NH₃ solution is approximately ≈ 2.2 x 10⁻⁵ M (moles per liter)

. An object with a mass of 1.0 kg is attached to a spring and is set into

vibration with a period of 3.0 s. What will be the calculated spring

constant?

### Answers

The calculated **spring constant **is approximately (9.0 s^2 / 4π^2) kg.

The period of vibration of an object attached to a spring is related to the mass of the **object** and the spring constant. The formula to calculate the period (T) of an **oscillating** mass-spring system is:

T = 2π√(m/k)

Where:

T = period of vibration

m = mass of the object

k = spring constant

In this case, the **period** (T) is given as 3.0 seconds, and the mass (m) is 1.0 kg. We can rearrange the formula to solve for the spring constant (k):

T = 2π√(m/k)

(3.0 s) = 2π√(1.0 kg/k)

Now, we can isolate k:

(3.0 s) / (2π) = √(1.0 kg/k)

(3.0 s) / (2π) = √(k/1.0 kg)

Square both sides:

(3.0 s / 2π)^2 = k / 1.0 kg

Simplifying:

(9.0 s^2 / 4π^2) = k / 1.0 kg

Multiplying both sides by 1.0 kg:

k = (9.0 s^2 / 4π^2) kg

Therefore, the calculated spring constant is approximately (9.0 s^2 / 4π^2) kg.

### Answers

The **volume** of the red bird feeder is approximately 217 cubic inches. The volume of the blue bird feeder is approximately 339 cubic inches. The total volume of Mia's bird feeders is **approximately 556 cubic** inches.

To find the volume of a cylindrical object, we use the formula V = πr^2h, where V is the volume, π is a constant (we can use 3.14 as an approximation), r is the radius, and h is the height.

For the red bird feeder, we know that the diameter is 10 inches, so the radius is 5 inches (half of the diameter). The height is given as 8.3 inches. Plugging these values into the formula, we get V = 3.14 x 5^2 x 8.3, which simplifies to approximately 217 cubic inches when rounded to the nearest whole number.

For the blue **bird feeder**, we know that the diameter is 12 inches, so the radius is 6 inches. The height is given as 7.5 inches. Plugging these values into the formula, we get V = 3.14 x 6^2 x 7.5, which simplifies to approximately 339 cubic inches when rounded to the nearest whole number.

To find the total volume of Mia's bird feeders, we simply add the volumes of the red and blue bird feeders. This gives us 217 + 339 = 556 cubic inches, which rounds to approximately 556 when rounded to the nearest whole number.

Two resistors are connected in parallel across a potential difference. The resistance of resistor A is twice that of resistor B. if the current carried by resistor A is I, what is the current carried by resistor b?

### Answers

When two **resistors **are connected in **parallel **across a potential difference, the potential difference across each **resistor **is the same. Let's assume that the **potential **difference across the resistors is V.

Now, we know that the resistance of resistor A is twice that of resistor B. Let's assume that the resistance of resistor B is R. Therefore, the resistance of resistor A is 2R.

Using **Ohm's law, **we know that the current through a resistor is directly proportional to the potential difference across it and inversely proportional to its **resistance**. So, the current through resistor A can be expressed as:

I = V / (2R)

Similarly, the current through resistor B can be expressed as:

I_b = V / R

We can simplify this expression by **substituting** the value of I from the first equation:

I_b = V / R = (2I) / R = 2(I/R)

Therefore, the current carried by resistor B is twice the current carried by resistor A.

### Answers

To derive the **expression** for the period of a **physical pendulum** with a finite-sized ball, we need to consider the total moment of inertia of the pendulum.

Using the** parallel axis theorem**, we can calculate the total moment of inertia of the pendulum, which is the sum of the moment of inertia of the ball and the moment of inertia of the **pendulum** rod. The moment of **inertia of the ball** about an axis through the centre of the ball is given by:

I_ball = (2/5) * m * r^2, where m is the mass of the ball and r is the radius of the ball.

The moment of inertia of the pendulum rod can be approximated as:

I_rod = m * L^2, where L is the length of the pendulum.

The total moment of inertia of the pendulum is the sum of these two components:I_total = I_ball + I_rod.

Substituting the values of I_ball and I_rod: I_total = (2/5) * m * r^2 + m * L^2., Now we can use this expression for the total **moment of inertia** in the formula for the period of the physical pendulum:

T = 2π * sqrt(I_total / (m * g * h)).

Substituting the value of I_total:

T = 2π * sqrt(((2/5) * m * r^2 + m * L^2) / (m * g * h)).

Simplifying the expression:

T = 2π * sqrt((2/5 * r^2 + L^2) / (g * h)).

Therefore, the expression for the period of a physical **pendulum** with a finite-sized ball is T = 2π * sqrt((2/5 * r^2 + L^2) / (g * h)).

### Answers

The magnitude of the **centripetal acceleration** of the car is approximately 4.85 m/s².

To find the magnitude of the centripetal acceleration of the car, first, we need to determine its speed and then use the centripetal acceleration formula. The given information is that the car and driver have a combined mass of 600 kg, the track radius is 160 m, and the time to complete one lap is 36 s.

Step 1: Calculate the speed of the car

To do this, we'll first find the circumference of the circular track, which is C = 2πr. Using the given radius (r = 160 m) and π = 3.142, we get:**C = 2 × 3.142 × 160 m = 1004.48 m**

Now, divide the circumference by the time taken to complete one lap (36 s) to find the speed:**Speed = C / Time = 1004.48 m / 36 s ≈ 27.9 m/s**

Step 2: Calculate the centripetal acceleration

Use the centripetal acceleration formula:

**a_c = v^2 / r**, where v is the speed and r is the radius. Substituting the values we found:

a_c = (27.9 m/s)^2 / 160 m ≈ 4.85 m/s²

Thus, the magnitude of the centripetal acceleration of the car is approximately **4.85 m/s²**.

what was the helicopter’s final momentum? Show all work to receive credit.

### Answers

The **helicopter's** final **momentum** is 3,750,000 kg·m/s.

To calculate the force used to accelerate the **helicopter**, we can use Newton's second law of motion, which states that the force (F) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a):

F = m * a

Given:

Mass of the helicopter (m) = 15,000 kg

Initial velocity (u) = 180 m/s

Final velocity (v) = 250 m/s

Time taken (t) = 6 s

To calculate acceleration (a), we can use the formula:

a = (v - u) / t

Substituting the given values:

a = (250 m/s - 180 m/s) / 6 s

a = 70 m/s / 6 s

a = 11.67 m/s²

Now we can calculate the force (F):

F = m * a

F = 15,000 kg * 11.67 m/s²

F ≈ 175,050 N

Therefore, the force used to accelerate the helicopter is approximately 175,050 Newtons.

To calculate the final **momentum** of the helicopter, we can use the formula:

Momentum (p) = mass (m) * velocity (v)

Substituting the given values:

Momentum (p) = 15,000 kg * 250 m/s

Momentum (p) = 3,750,000 kg·m/s

Therefore, The helicopter's final momentum is 3,750,000 kg·m/s.

at 200k, the volume of a gas is 100 ml. if the temperature is raised to 300k, what is the new volume?

### Answers

To solve this problem, we'll use **Charles's Law,** which states that the volume of a gas is directly proportional to its temperature when the pressure and the amount of gas are kept constant. Mathematically, the law can be expressed as V1/T1 = V2/T2, where V1 and V2 are the initial and final volumes, and T1 and T2 are the **initial and final temperatures.**

In this case, we're given:

V1 = 100 mL (initial volume)

T1 = 200 K (initial temperature)

T2 = 300 K (final temperature)

We need to find V2 (final volume).

Applying Charles's Law, we get:

(100 mL) / (200 K) = V2 / (300 K)

Now, we can solve for V2:

V2 = (100 mL) * (300 K) / (200 K)

V2 = 30000 mL / 200 K

V2 = 150 mL

So, the new volume of the gas at 300 K is 150 mL. In summary, when the temperature of the gas increased from 200 K to 300 K, its volume increased from 100 mL to 150 mL due to the** direct proportionality** between the volume and **temperature of a gas** as stated by Charles's Law.

True or false in parts of latin america, economic chaos helped dictators rise to power.

### Answers

It is true that in parts of** Latin America**, economic chaos and political instability have contributed to the rise of dictators. In countries such as Chile, Argentina, and Brazil, economic crises and social unrest provided the conditions for authoritarian leaders to seize power.

For example, in Chile, the socialist government of **Salvador** Allende was overthrown by General Augusto Pinochet in a military coup in 1973, partly due to the economic crisis and hyperinflation that the country was facing at the time. Similarly, in Argentina, the military junta that ruled the country from 1976 to 1983 came to power during a period of economic and **political** turmoil known as the "Dirty War".

The regime used violence and repression to maintain control and suppress dissent. In Brazil, the military dictatorship that ruled from 1964 to 1985 was also supported by a significant portion of the population that was fearful of the **economic **instability and social unrest that plagued the country in the 1960s and 1970s. In summary, economic chaos has been a contributing factor in the rise of dictators in Latin America.

suzanna notices that when she rolls a marble on the carpet, the marble slows down and stops. what

force causes the marble to change its motion? how does this force act?

### Answers

Different materials will produce different amounts of **friction**, and that the frictional force will be stronger when the surfaces are pressed together more tightly.

The force that causes the marble to change its **motion **is friction. Friction is the force that opposes motion between two surfaces that are in contact. In this case, the carpet and the marble are in contact, and the friction between them causes the marble to slow down and eventually stop.

The force of friction acts in the opposite **direction** to the motion of the marble, meaning that it acts in the opposite direction to the force that is causing the marble to roll in the first place. This is why the marble eventually stops rolling - the force of friction gradually overcomes the force causing the marble to roll, and the marble comes to a halt. It's important to note that the amount of friction depends on the nature of the surfaces in contact, as well as the force with which they are pressed together.

This means that different materials will produce different amounts of friction, and that the **frictional force** will be stronger when the surfaces are pressed together more tightly.

a block of ice sliding down an incline has its maximum speed at?

A) the top.

B) the bottom.

C) halfway down.

D) difficult to predict without knowing the slope of the incline

E) difficult to predict without knowing the coefficient of friction

### Answers

The **maximum speed** of a block of ice sliding down an incline depends on several factors, including the slope of the incline and the coefficient of friction between the block and the surface. Assuming that the incline is **frictionless**, the block will **accelerate **as it slides down the slope and reach its** maximum speed** at the bottom.

This is because the **gravitational force** acting on the block is the only force acting on it, and it gains kinetic energy as it moves down the incline. However, if there is friction between the block and the surface, the **maximum speed** will occur before the bottom of the incline, depending on the coefficient of **friction**. In general, the lower the coefficient of friction, the closer the** maximum speed** will be to the bottom of the incline. Therefore, the answer to the question is B) the bottom, assuming a frictionless surface, but it is difficult to predict without knowing the coefficient of friction if the surface is not **frictionless.**

1.38 c of charge flow out of a 9.00 v battery in 11.8 s. how much resistance is attached to the battery?

### Answers

**Answer: **The **resistance** attached to the battery = **0.117** Ω

**Explanation:**

We know that **I = Q/t** .....(i)

where, I ⇒ Current

Q ⇒ Charge flowing

t ⇒ Time taken

Now, as we know from Ohm's law,

**V = IR**

or, **R = V/I **....(ii)

where, R ⇒ Resistance

V ⇒ Voltage difference

I ⇒ Current

Putting the value of I from equation (i) in equation (ii),

**R = V / (Q/t)** ....(iii)

Now as per the question,

**Voltage of battery,** **V** = 9.00 Volt

**Charge flow, Q** = 1.38 Coulomb

**Time, t** = 11.8 seconds

A line drawn north is labeled 7 kilometers and a line drawn west is labeled 11 kilometers. 7. 7 km 8. 4 km 13. 0 km 18. 0 km.

### Answers

Samantha and Mia would be approximately 13.0 kilometers apart after one hour. (rounded to the nearest tenth). To find the **distance** between Samantha and Mia after one hour, we can use the Pythagorean theorem. option(c)

The triangle formed by their paths is a right **triangle**. Let's label the distance between Samantha and Mia as 'd'. We know that Mia walked north for 7 kilometers and Samantha ran west for 11 kilometers. After one hour, Mia would have traveled 7 kilometers, and Samantha would have **traveled** 11 kilometers.

Using the **Pythagorean** theorem, we can find 'd' as follows:

d^2 = (7 km)^2 + (11 km)^2

d^2 = 49 km^2 + 121 km^2

d^2 = 170 km^2

Taking the square root of both sides, we get:

d = sqrt(170) ≈ 13.0 km (rounded to the nearest tenth). option(c)
