Answer:
question 1: force
question 2: velocity or inertia
question 3: 0
r1 = 5*10^10 m , r2 = 6*10^12 m
v1 = 9*10^4 m/s
From conservation of energy
K1 +U1 = K2 +U2
0.5mv1^2 - GMm/r1 = 0.5mv2^2 - GMm/r2
0.5v1^2 - GM/r1 = 0.5v2^2 - GM/r2
M is mass of sun = 1.98*10^30 kg
G = 6.67*10^-11 N.m^2/kg^2
0.5*(9*10^4)^2 - (6.67*10^-11*1.98*10^30/(5*10^10)) = 0.5v2^2 - (6.67*10^-11*1.98*10^30/(6*10^12))
v2 = 5.35*10^4 m/s

The correct answer is C. microwaves, infrared, visible, gamma rays
Electromagnetic waves arranged in order of frequencies and wavelengths form the electromagnetic spectrum. In the order of decreasing frequency we obtain the following sequence.
Gamma ray>x-ray>ultraviolet >visible light>infrared light>microwaves>radio waves.
According to the Einsteins equation, E=hf, Energy is directly proportional to frequency. the higher the frequency the higher the energy of the photon and vice-versa.
