Complete Question 
For each of the following scenarios, describe the force providing the centripetal force for the motion:
a. a car making a turn
b. a child swinging around a pole
c. a person sitting on a bench facing the center of a carousel
d. a rock swinging on a string
e. the Earth orbiting the Sun.
Answer:
Considering a 
     The force providing the centripetal force is the frictional force on the tires \
           i.e  
     where  is the coefficient of static friction
 is the coefficient of static friction 
Considering b
    The force providing the centripetal force is the force experienced by the boys  hand on the pole 
Considering c 
      The force providing the centripetal force is the normal from the bench due to the boys weight 
Considering d 
      The force providing the centripetal force is the tension on the string 
Considering e
       The force providing the centripetal force is the force of gravity between the earth and the sun

Highest energy photon absorbed: 
Explanation:
An atom is said to be (positively) ionised when it absorbs a photon, and as a consequence, an electron becomes energetic enough to escape the atom, leaving an excess of positive charge behind.
In order for the electron to escape, the energy of the absorbed photon must be exactly equal to the (negative) energy of the level in which the electron lies.
For an hydrogen atom, the energy levels are given by

where this energy is measured in electronvolts, and n is the number of the energy level.
Since the energy is negative, this means that the electron which requires most energy is the one lying in the ground state (n=1). Therefore, for an electron in the ground state, the most energy that can be absorbed from the incoming photon is

Converting into Joules, this is equal to
