Answer:

Explanation:
Given that,
The wavelength of x ray, 
We need to find the energy if a photon on the x-rays. The formula for the energy of the photon is given by :



So, the energy of a photon of the X-rays is
. Hence, this is the required solution.
Answer A, low energy and long wavelength.
Answer:
1500 Joules
Explanation:
Work = Force x Distance
When multiplying by 10 you simply shift all the digits to the
left and append a 0 to the end.
so 150 x 10 = 1500 Joules
Yes it was. All the creator wanted to do was go into space
