Answer:
A) Φ = 0
, B)  T = 7.76 s
Explanation:
A) to find the value of the phase constant replace the value
           0 = a sin (b (0- 0) + Φ)
            0 = sin Φ
            Φ = sin⁻¹ 0
            Φ = 0
B) the period is defined by time or when the movement begins to repeat itself
So that the sine function is repeated when the angle passes 2pi
             b (x- ct) = 2pi
If we are at a fixed point x = 0
            b c t = 2pi
             t = 2π / bc
Let's calculate
             T = 2π / (33.05 245)
             T = 7.76 s

(D) The gravitational force between the astronaut and the asteroid. 
Reason : 
All the other forces given in the options, except (D), doesn't account for the motion of the astronaut. They are the forces that act between nucleons or atoms and neither of them accounts for an objects motion.
