I believe your answer is C. my friend!
The temperature of the substance giving off the heat decreases while the temperature of the substance receilving the heat increases. they leach what is called equlibrium point where heat energy can longer be exchanged hence equql temperature. this isThermal physics

Explanation:
Given that,
Amplitude, A = 2.5 nm
Wavelength,
The speed of the wave, v = 36 m/s
At time t = 0 the left end of the string has its maximum upward displacement.
(a) Let f is the frequency. So,
(b) Angular frequency of the wave,
(c) The wave number of the wave
