The answers are 6.2 x 10^18 electrons and 5.7 x 10^-12 kg respectively.
Answer:
B. 832 m/s
Explanation:
(1/2) (0.015) v^2 = (3/2) (1.5) (8.31) (278)
0.0075 v^2 = 5197.905
v^2 = 693054
v = 832.49
The momentum of the
x-ray photon is p = h/lambda . Lambda is the wavelength (0.30nm=3x10^(-9)m) and
h is Planck's constant,(h=6.62607004 × 10-34<span> m2 kg / s).The
momentum is: 2.2 x 10^(-25).</span>
The momentum can be calculated
also as: p=mv, where m is the mass of the electron and v is the speed.
So v=p/m,p is known,and
also the mass of the electron (m=9.10938356 × 10-31<span> kilograms).</span>
v=2.2 x 10^(-25)/9.10938356
× 10-31<span> kilograms=0.24 x 10^6 m/s</span>
