Amoon orbits an isolated planet in deep space. which of the following forces that the planet exerts on the moon can be considered negligible?

a) the electric force
b) the force due to gravity.
c) both the electric force and the force due to gravity
d) neither the electric force nor the force due to gravity

explain

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

When an object is heated it contracts. a. true b. false

One form of energy can be another type of energy. a. created to form b. transformed into c. destroyed and then created to form
