Energy is the capacity to do some type of work
Zero maximum force (N) or field strength (N/C). ... minimum /maximum field strength.
Answer:
C. The gravity acceleration is in the same direction as the force of gravity, and thus toward the center of the earth.
Explanation:
[ More info.- It doesn't affect the body when it is at the rest, and when it is in motion, it acts toward the center of the Earth and it's component is known as "Centripetal force" ]

In order to calculate the weight, we may simply use:
W = mg
W = 30 * 9.81
W = 294.3 N
The sum of the reaction force and the upward component of child pulling will be equal to total downward force. The force acting downwards is the weight. Therefore:
R + 12sin(45) = 294.3
R = 285.82 N
The acceleration can be found using the resultant force and the mass of the sled. The resultant force is:
F(r) = pulling force + pushing force - friction
F(r) = 12cos(45) + 8 - 5
F(r) = 11.48 N
a = F/m
a = 11.48 / 30
a = 0.38 m/s²
Answer:
from the formula of work done =Force *Distance 500*100=50000
