Answer:
b. The horizontal component of the normal force acts toward the center of the circle.
Explanation:
When a car on a banked turn move with just the right speed so that the frictional force is zero, a component of the normal force -which is always perpendicular to the surface- acts as the centripetal force on the car. This is because the normal force now has a horizontal component, and this component supplies the centripetal force.
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
It’s coming in contact with more air molecules than I would if it was in a ball because there is less surface area
