Answer:
0.29D
Explanation:
Given that
F = G M m / r2
F = GM(6m) / (D-r)2
G Mm/r2 = GM(6m) / (D-r)2
1/r2 = 6 / (D-r)2
r = D / (Ö6 + 1)
r = 0.29 D

Answer:
Speed, S = 0.5m/s
Explanation:
Given the following data;
Distance = 30 meters
Time = 1 minute = 60 seconds
To find the speed;
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
Substituting into the above formula;
Speed, S = 0.5m/s
Dependent variable is your answer.
