The collision between a photon or a bundle of energy and an electron is known as the Compton Effect in which there is a transference of energy and momentum by the photon to the recoiling electron. It must be noted that both energy and momentum are being conserved during this elastic collision. After such phenomena, the photon acquires energy (represented by hf/) and the electron also has acquired a kinetic energy (represented by K).
Answer:
Explanation:
From A to B
distance traveled with velocity 
in time 
from B to C
distance traveled is 0.5 d with 
and 
velocity for half-half time
divide 1 and 2 we get
Now average velocity is given by
taking common
I think its C. because metal is a good conductor of heat
I hope this helps ^-^
let me know if im wrong
