Gravity is a force between any two objects with mass. Why doesn't a person feel a gravitational force between him/herself and another person?A) A person doesn't exert a gravitational force.

B) The two gravitational forces cancel each other out.

C) The gravitational forces of people is so small it is
overshadowed by that of Earth.

D) There are so many people we are actually balanced by all the different gravitational forces.

Answers

The answer would be C. The gravitational force between two bodies however it is too small that it is overshadowed by that of earth. Gravitational force is the weakest force of all. Each body with a mass exerts a gravitational force onto each other but this value is so small that it can be neglected.

When 10 N force applied at 30 degrees to the end of a 20 cm handle of a wrench, it was just able to loosen the nut. What magnitude of the force would require to just loosen the nut, if the force apply perpendicularly at the end of the handle

Answers

Answer:

5N

Explanation:

To get the magnitude of the force would require to just loosen the nut, if the force apply perpendicularly at the end of the handle, we will have to resolve the force perpendicular to the wrench. Torque is the turning effect of a body or force about a point. It is similar to moments.

Torque = Force * radius

Note that the force must be perpendicular to the wrench. On resolving the force perpendicularly to the wrench, we will have to resolve the force to the vertical.

Fy = Fsinθ

Fy = 10sin30°

Fy = 10 * 0.5

Fy = 5N

Torque = Fy * r

Given Fy = 5N and r = 20cm = 0.2m

Torque = 5 * 0.2

Torque = 1Nm

Hence the magnitude of the force would require to just loosen the nut, if the force apply perpendicularly at the end of the handle is 5N
