An oscillator makes four vibrations in one second. What is its period and frequency?

Answers

Frequency = no. of oscillations/ time

= 4 / 1
= 4Hz

Time period = 1/ frequency

= 1/ 4

A stationary police officer directs radio waves emitted by a radar gun at a vehicle moving toward the officer. Compared to the emitted radio waves, the radio waves reflected from the vehicle and received by the radar gun have a(1)longer wavelength
(2)higher speed
(3)longer period
(4)higher frequency

Answers

Answer: The correct answer is higher frequency.

Explanation:

Doppler's effect is defined as the apparent change in the frequency of an electromagnetic wave due to the relative motion of an observer and source.

In the given problem, a stationary police officer directs radio waves emitted by a radar gun at a vehicle moving toward the officer. In this case, there will be higher frequency.

If a stationary police officer directs radio waves emitted by a radar gun at a vehicle moving away the officer. In this case, there will be smaller frequency but will have a longer wavelength.

Therefore, the radio waves reflected from the vehicle and received by the radar gun have a higher frequency.

The emitted radio waves, the radio waves reflected from the vehicle and received by the radar gun have a higher wavelength.

What is the Doppler effect?

A sudden change in the frequency due to the distance between the objects and source is explained by the doppler effect.

As the source and observer travel toward each other, the frequency of sound, light, or other waves increases or decreases.

The emitted radio waves, the radio waves reflected from the vehicle and received by the radar gun have a higher wavelength.

Hence option 4 is correct.

Whats is the definition of Parallel Circuit

Answers

A parallel circuit is one in which there's a place where the flow of current
can split up and follow different paths.

An example might be:
Two lamps plugged into the same outlet and both turned on.

Current that comes out of the outlet splits up, and parts of it flow
through each lamp.

No . of devices when connected parallely or when they don't depend on each other to conduct electricity makes a parallel circuit.

What’s the kinetic energy of the object? Use .Erica is competing in the shot put event at a track meet. She hurls a shot with a mass of 4 kilograms at a speed of 9 meters/second. The shot’s kinetic energy is joules.

Answers

The kinetic energy of an object varies directly with the square of the speed of an object. The required kinetic energy of the shot is f 162 J.

What is Kinetic Energy?

The energy possessed by an object by its motion is known as the object's kinetic energy. It depends on the speed and mass of the given object.

Given data -

The mass of shot put is, m = 4 kg.

The speed of shot put is, v = 9 m/s.

The mathematical expression for the kinetic energy of the shot put is,

$KE = (1)/(2) m v^(2)$

Solving as.

$KE = (1)/(2) * 4 * 9^(2)\n\nKE = 162 \;\rm J$

Thus, we can conclude that the required kinetic energy of the shot is of 162 J.

Answer:

We have: K.E. = mv² / 2

here, m = 4 Kg

v = 9 m/s

Substitute their values into the expression:

K.E. = (4)(9)² / 2

K.E. = (4)(81) / 2

K.E. = 324 / 2

K.E. = 162 Joules

Explanation:

In short answer: it would be K.E.=162 Joules

The atmosphere and oceans are constantly moving. Their activity is due primarily to _____. the Sun's energy the moon's gravity the earth's gravity air pressure

Answers

Answer:

It is primarily due the Sun.

Explanation:

Sun is the ultimate source of energy.

Due to the heat of Sun, the atmosphere heats up unevenly. Due to which there is a temperature difference between the two regions. As the temperature difference is maintained, the air flows, i.e., atmosphere is moving.

Similarly, water gets heat up unevenly in oceans. Due to which a temperature difference is maintained between two points in the ocean and thus the oeans are moving constantly.
