Answer:
The energy of a single photon of X‑rays is
Explanation:
From the question we are told that
The mass of the tissue is
The amount of energy delivered is
The wavelength is
Generally the energy of a single photon is mathematically represented as
Where h is the Planck's constant with values
and c is the speed of light with values
Substituting values
Converting this to electron volt we have
The magnitude of the kinetic friction force, ƒk, on an object is. Where μk is called the kinetic friction coefficient and |FN| is the magnitude of the normal force of the surface on the sliding object. The kinetic friction coefficient is entirely determined by the materials of the sliding surfaces. hope it helps
