The mri (magnetic resonance imaging) body scanners used in hospitals operate at a frequency of 400 mhz (m = 106 ). calculate the energy for a photon having this frequency. for credit show all your work including correct units.

Energy,

Explanation:

It is given that,

The MRI (Magnetic Resonance Imaging) body scanners used in hospitals operate at a frequency of 400 MHz,

We need to find the energy for a photon having this frequency. The energy of a photon is given by :

So, the energy of the photon is . Hence, this is the required solution.

where is the photo and the answer choices?

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
