Sublimation is the changing of a solid directly to a gas without turning into a liquid first. Where as vaporization is the liquid turning into a gas.
The energy carried by a single photon is given by
where h is the Planck's constant and f is the frequency of the photon.
The photon of our exercise has a frequency of
, therefore its energy is
The answer for this problem is False
The correct answer is:
<span>c)the object will remain in static equilibrium
In fact, Newton's second law states that the resultant of the forces acting on an object is equal to the product between the mass of the object and its acceleration.
In this problem, we have two forces of equal magnitude but acting into opposite directions, along the same line. This means that the net force acting on the object is zero, so the acceleration of the object is zero, and so the body (which is rigid, so it cannot deform) will remain in static equilibrium.</span>
