23.5 DEGREES is the answer.
B strength training I think that’s the answer
Answer:
The energy of photon, 
Explanation:
It is given that,
Voltage of anode, 
We need to find the maximum energy of the photon of the x- ray radiation. The energy required to raise an electron through one volt is called electron volt.

e is charge of electron


So, the maximum energy of the x- ray radiation is
. Hence, this is the required solution.
Answer:
Part a)

Part b)

Part c)

Explanation:
Part a)
Moment of inertia of the system about an axis passing through B and C is given as




Part b)
Moment of inertia of the system about an axis passing through A and C is given as




Part c)
Moment of inertia of the system about an axis passing through the center of the square and perpendicular to the plane of the square
