Object A has a positive charge of 3.0 x 10-6 C. Object B has a positive charge of 9.0 x 10-6 C. If the distance between A and B is 0.015 m, what is the force on A?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Alarge box of mass m is pulled across a horizontal frictionless surface by a horizontal rope with tension t. a small box of mass m sits on top of the large box. the coefficients of static and

Aforklift raises a box above the floor and does 2,000 j of work. if the forklift motor consumes 3,000 j of electrical energy from the battery to raise the box, what is the efficiency of the lift?
