Answer:
The velocity of the photo electron is .
Explanation:
Given that,
Supplied energy,
Minimum energy of the electron to escape from the metal,
We need to find the velocity of the photo electron. The energy supplied by the photon is equal to the sum of minimum escape energy and the kinetic energy of the escaping electron. So,
The formula of kinetic energy is given by :
So, the velocity of the photo electron is .
Answer with Explanation:
We are given that
a.We have to find the total dose
Total dose=
Using the formula then, we get
b.We have to find the total dose equivalent
Total dose equivalent=H=
Using the formula
H=3.1mSv
Answer:
θ=142.9°
Explanation:
d=1 *r
angle ϕ= 37.1°
the line connecting pebble and target should be tangent to a circle so
cos(180-ϕ-θ)==
∴ θ=180-ϕ-
θ= 180-37.1-0
θ=142.9°
