3- (a) what is the period of rotation of earth in seconds? (b) what is the angular velocity of earth? (c) given that earth has a radius of at its equator, what is the linear velocity at earth's surface?

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.
