How many x-ray photons per second are created by an x-ray tube that produces a flux of x rays having a power of 1.00 W? Assume the average energy per photon in 78.0 keV.

The correct solution is "".

Explanation:

Given:

Power,

P = 1.00 W

Time,

t = 1 sec

Average energy,

E₀ = 78.0 KeV

Or,

    =

    =

As we know,

⇒

or,

⇒        

⇒      

⇒            

b.

explanation:

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
