Answer:
D.Oval
Explanation:
because it is not completely circular
Work = Force multiplied by the distance(or displacement)
To calculate the gravitational force acting on an object given the mass and the acceleration due to gravity, use the following formula.
Fg = m • g
Fg = 1.3 kg • 9.8 m/s^2
Fg = 12.74 N or about 12.7 N.
The solution is C. 12.7 N.
