The answer is the Doppler Effect
maxonik [38]3 years ago

Answer: The correct answer is Doppler effect.

Explanation:

When there is relative motion between the source and listener then there is an apparent change in the frequency of the sound wave. This phenomenon is called the Doppler effect.

Pitch depends on the frequency.

If the listener and the source are approaching each other then the frequency increases.

If the listener and the source are moving away from each other then the frequency decreases.

Therefore, the Doppler effect is the change of pitch heard when the source of the sound approaches and then moves away from a stationary person.

Anit [1.1K]

Answer:

b.only when the current in the first coil changes.

Explanation:

An induced current flow in the second coil only when there is a change in current in the first cool. A steady current will produce no change in flux (due to magnetic effect of a current) by the first coil, and according to Faraday, induced current is only produced when there is a change in flux linkage.

If it takes 600 N to move a box 5 meters, how much work is done on the box?
Anika [276]

Answer:

<h2>3000 J</h2>

Option C is the correct option.

Explanation:

Given,

Force = 600 N

Distance = 5 meters

Work = ?

Now,

Work = Force \times distance

= 600  \times 5

Calculate the product

= 3000 \: Joule

Hope this helps...

Good luck on your assignment..

Small rockets are used to make small adjustments in the speed of satellites. One such rocket has a thrust of 42 N. If it is fire
Over [174]

To solve this problem we will apply the concepts related to Newton's second law that relates force as the product between acceleration and mass. From there, we will get the acceleration. Finally, through the cinematic equations of motion we will find the time required by the object.

If the Force (F) is 42N on an object of mass (m) of 83000kg we have that the acceleration would be by Newton's second law.

F = ma \rightarrow a = \frac{F}{m}

Replacing,

a =\frac{42N}{83000kg}

a =5.06*10^{-4}m/s^2

The total speed change

\Delta v = v_f -v_0 \rightarrow v_f =\text{Final velocity and } v_0 = \text{Initial velocity } we have that the value is 0.71m/s

If we know that acceleration is the change of speed in a fraction of time,

a= \frac{\Delta v}{t} \rightarrow t = \frac{\Delta v}{a}

We have that,

t= \frac{0.71m/s}{5.06*10^{-4}m/s^2 }

t = 1403.16s

Therefore the Rocket should be fired around to 1403.16s
