A freely falling object is dropped from rest, what is its speed after falling 1 second? 2 seconds? 3 seconds? 10 seconds?

The tangential speed on the outer edge of a rotating carousel is dependent on the carousel's rotational speed and the distance from the center of rotation to the outer edge.

It can be calculated using the formula: tangential speed = radius × angular speed

Where the radius is the distance from the center of rotation to the outer edge, and the angular speed is the rate of rotation measured in radians per second.

The carousel's rotational speed of a carousel refers to the rate at which it completes one full revolution, and it is usually measured in units of revolutions per minute (RPM) or radians per second (rad/s). The faster the carousel rotates, the higher the outer edge's tangential speed. The rotational speed of a carousel can be controlled by adjusting the power source that drives it, such as an electric motor.

1 For a sound wave, the pitch is determined by which wave characteristic?

A - Frequency

2 Which of the following waves cannot be transmitted through a vacuum?

C - Sound waves

3 Which of the following could be the value of a wavelength that is found in the visible region of the electromagnetic spectrum?

B - 5 × 10^-7 m

4 Sophie is trying to measure the speed of sound. She stands 24.0 m away from a wall and claps repeatedly, changing the frequency until the echo synchronized with her claps. If she calculates the speed of sound as 325 m • s-1 how long did she wait between claps?

The time between her claps and the echo is twice the time it takes for the sound to travel from her to the wall. Therefore, the time between her claps is:

time = distance/speed = 2 x 24.0 m/325 m/s = 0.148 seconds (to three significant figures).

So the answer is 0.148, without units and correct to three significant figures

Answer:

I. The angle θ increases, and the pattern expands away from the bright center

II. The angle θ increases, and the pattern expands away from the bright center

Explanation:

The given information are;

The light used to produce a diffraction pattern = Blue light

The formula for refraction is given as follows;

d × sin(θ) = n·λ

Where;

d = The inter slit distance

θ = The angle to the maxima

n = Number to the integer next fringe

λ = Light wavelength

The wavelength of blue light is between 450 and 495 nanometers

Therefore;

I. When we switch to yellow light

The wavelength of yellow light is between 590 and 560 nanometers, which is an increase in wavelength, given that d, the inter slit distance is held constant, the angle θ increases, and the pattern expands away from the bright center

II. Decrease the slit width

When the slit width is decreased, and the wavelength remains the same, the angle θ increases, and the pattern expands away from the bright center.

Answer:

The amount of power will be increased.

Explanation:

If the work remains constant but the time is reduced the power increases. Since power is defined as the relationship between work overtime. By means of the following equation, we can see this relationship.

\(P=W/t\)

where:

P = power [Watts]

W = work [J] (units of joules)

t = time [s]

Let's assume with an example the above written.

If we have an electric motor that exerts a work of 950 [J], and the time used is 5 [s], the power is:

\(P = 950/5\\P = 190 [W]\)

Now if we want to accelerate the work done and use 2 seconds for the time, we will have:

\(P=950/2\\P=475 [W]\)

We want to see how maintaining the work constant but reducing the time in which it occurs affects the power. We will see that the power increases.

We define power as the amount of work done per unit of time.

So we can compute power as the quotient between the work done and the time in which it is done.

So, if we reduce the time in which the work is done, then the denominator is smaller, thus, the power will be larger.

This means that maintaining the work constant, and reducing the time in which it is done, increases the amount of power exerted.

The acceleration of the skateboard from its initial velocity to the final velocity over the given time is 0.6m/s².

Motion is simply the change in position of an object over time.

From the First Equation of Motion;

v = u + at

Where v is final velocity, u is initial velocity, a is acceleration and t is time elapsed.

Given the data in the question;

To determine the acceleration of the skateboard, we substitute our given values into the expression above.

v = u + at

10m/s = 4m/s + ( a × 10s)

( a × 10s) = 10m/s - 4m/s

a × 10s = 6m/s

a = 6m/s ÷ 10s

a = 0.6m/s²

Therefore, the acceleration of the skateboard from its initial velocity to the final velocity over the given time is 0.6m/s².

Calculate the potential temperature of air at 50mb and 250 K using the formula: potential temperature = temperature * (Reference Pressure / Current Pressure)^(R/Cp).the potential temperature of the air at a pressure of 50mb and a temperature of 250 K is approximately 369.25 K.

To calculate the potential temperature of air at a pressure of 50mb and a temperature of 250 K, you can use the formula for potential temperature:

Potential temperature = Temperature * (Reference Pressure / Current Pressure)^(R/Cp)

In this case, the reference pressure is typically taken as 1000mb, the gas constant for dry air (R) is approximately 287 J/(kg·K), and the specific heat at constant pressure (Cp) is approximately 1005 J/(kg·K).

Plugging in the values, we get:

Potential temperature = 250 K * (1000 mb / 50 mb)^(287/1005)

Simplifying the calculation:

Potential temperature = 250 K * 20^(0.2856)

Using a calculator, we can find that 20^(0.2856) is approximately 1.477.

So, the potential temperature of the air is:

Potential temperature = 250 K * 1.477

Calculating this, we find that the potential temperature of the air is approximately 369.25 K.

Therefore, the potential temperature of the air at a pressure of 50mb and a temperature of 250 K is approximately 369.25 K.

MACHOs, or Massive Compact Halo Objects, are a type of dark matter candidate consisting of large, non-luminous celestial bodies.

MACHOs are thought to be made up of baryonic matter (protons, neutrons, and electrons), but they do not emit or reflect enough light to be easily detected.

They are theorized to reside in the halo region surrounding galaxies like the Milky Way.

Examples of MACHOs include black holes, neutron stars, and brown dwarfs. Due to their massive size and gravitational influence, they are considered as potential contributors to the unaccounted mass in the universe, known as dark matter.

The average velocity or displacement of a particle for the first time interval is Δs / Δt = 6 cm/s.

Solution:

As we know that displacement is calculated in centimeters and the unit of time is second.

The average velocity for the first interval [1,2] is given

Δs / Δt = s (t2) - s (t) / t2 - t1

Δs / Δt = 2sin2  π  + 3cos 2 π -  ( 2sin π + 3cos π ) / 2 - 1

Δs / Δt = 2(0) + 3(1) - 2(0) - 3 (-1) / 1

The vertical force exerted by the tower on the pin at A is 924 lb by understanding the principles of tension and equilibrium is essential in engineering and designing transmission towers.

The tension in the wire AB, which is 924 lb, is equal to the vertical force exerted by the tower on the pin at A. This is because in a state of equilibrium, the sum of all vertical forces acting on the tower must be balanced. The tension in the wire AB provides the vertical support necessary to counteract the tower's weight and maintain equilibrium.

In this scenario, the tower is held by three guy wires, with AB being one of them. The tension in AB is the only vertical force acting on the pin at A since the other guy wires (BC and BD) are anchored by bolts at points B, C, and D respectively. The tension in the wire BC and BD will have horizontal components that cancel each other out, resulting in no net vertical force on the pin at A.

Therefore, the tension in AB, which is 924 lb, is the vertical force exerted by the tower on the pin at A.

In a system of guy wires supporting a tower, the tension in each wire plays a crucial role in maintaining stability and equilibrium. By distributing the forces properly, the tower can withstand external loads and remain structurally sound.
