Answer:
The energy becomes 4 times greater.
Explanation:
We know that the energy of a wave is proportional to the square of its amplitude
E ∝ Amplitude^2
Since the original amplitude = 0.5 m
and the new amplitude becomes = 1 m
We are doubling the amplitude. This means that the new energy will be affected by a factor of 4
E_new ∝ (2*Amplitude)^2 =
E_new ∝ 4*(Amplitude)^2
E_new = 4*E
Answer:If the object's speed increases.
Explanation:
If the object's speed increases, then its kinetic energy will increase. If the kinetic energy increases, the change in kinetic energy will be positive.
The units of velocity is :
meter per second (m/s)
