630.15 kelvin, 312.05 kelvin
0.29 m/s is the speed of this wave.
How can we determine a wave's speed?
Given: The wave's traveling wavelength is () = 35 cm
The wave's period (t) is 1.2 seconds.
The wave's frequency is 0.833 Hz.
We must ascertain a wave's wave speed.
Formula for wave speed is 35 x 0.833 (wavelength x frequency).
= 29.167 cm/sec
= 0.29 m/sec
As a result, the wave's speed is 0.29 m/s.

The engine's efficiency is (35J)/125J) = 28% .
Do you have a different question to ask ?
Yes, but the velocity of the bullet would have to be much higher. Because momentum is defined as p=mv, for a bullet, which has a much, much smaller mass than a car or a truck, to have the same value for p,
