Answer:

Resonance

Explanation:

In Physics when an object experience an applied force of certain frequency that matches the natural frequency of the object a phenomena called resonance occurs. When a force is applied at resonant frequency the system will oscillate at a higher amplitude as compared to the scenario when the same force is applied at a different frequency.

Answer: The correct answer is resonance.

Explanation:

Resonance occurs when the applied frequency on the object is equal to its natural frequency.

This is the reason why the soldiers are told not to march on the bridge. Otherwise, it will collapse. As the applied frequency on the bridge will equal to natural of the bridge.

Therefore, the correct option is resonance.

Consider two transformers. Transformer A has 300 turns on its primary and 500 turns on its secondary. Transformer B has 250 turn

rusak2 [61]

Answer:

Secondary voltage on second transformer is 200 volt.

Explanation:

It is given two transformer

Let us consider first transformer.

Number of turns in primary $N_p=300$

Numb er of turns in secondary $N_s=500$

Now consider second transformer

Number of turns in primary $N_p=250$

Number of turns in secondary $N_s=1000$

Now it is given that same voltage of 50 volt is applied to primary of both the transformer.

For second transformer

$\frac{N_p}{N_s}=\frac{V_p}{V_s}$

$\frac{250}{1000}=\frac{50}{V_s}$

$V_s=200volt$

So secondary voltage on second transformer is 200 volt

When an object accelerates, what about its motion changes? Question 1 options: Speed must change, but not velocity. Both speed a

QveST [7]

Answer:

The velocity must change but not speed.

Explanation:

Velocity is defined as the displacement by time. Whereas speed is expressed as the distance between two successive positions of the body to the time interval it took to travel.

Velocity, V = D / t m/s

Speed, s = d /t m/s

Velocity is a vector quantity that has a magnitude and direction.
The speed is a scalar quantity having only the magnitude.
At any instant of time, the magnitude of the velocity is always equal to the magnitude of the speed. The magnitude of velocity, |v | = magnitude of speed, |v |. The magnitude is always positive
The acceleration of a body is defined as the rate of change of velocity to time.

a = (v - u) / t m/s²

If a body is accelerating, It varies its velocity with respect to time.
In case of uniform circular motion, the speed remains constant, but the velocity changes continuously.

So, in the case of circular motion if an object accelerates, velocity must change but speed remains constant.
