Answer:
D. are brought from the mantle to the surface in magma that hardens into komatiite.
Explanation:
Diamond :
It is the hardest form of carbon.The atomic atoms arrange in the cubic crystal structure and this is known as diamond cubic.Another form of the diamond at room temperature is graphite.This is used for making jewelry.This is also used in the cutting process because it has high strength.
Therefore the correct option for the diamond is D.

Answer:
a) 
b)
c)
d)= 0 and the direction of motion is equal to zero
Explanation:
a) compton shift



b) the new wavelength



![=hc[\frac{1}{\lambda'}-\frac{1}{\lambda}]](https://tex.z-dn.net/?f=%3Dhc%5B%5Cfrac%7B1%7D%7B%5Clambda%27%7D-%5Cfrac%7B1%7D%7B%5Clambda%7D%5D)
![\Delta E = 6.626*10^{-34}*(3*10^8)[\frac{1}{14.84*10^{-12}}-\frac{1}{4.8*10^{-12}}]](https://tex.z-dn.net/?f=%5CDelta%20E%20%3D%206.626%2A10%5E%7B-34%7D%2A%283%2A10%5E8%29%5B%5Cfrac%7B1%7D%7B14.84%2A10%5E%7B-12%7D%7D-%5Cfrac%7B1%7D%7B4.8%2A10%5E%7B-12%7D%7D%5D)

C)By conservation of energy, the kinetic energy of recoiling electron is equal to the magnitude of energy between the photon energy

d) the angle between the positive direction of motion

= 0
the direction of motion is equal to zero.
A drag because the lift keeps it up and the drag brings it down
