1. Two very small slits are positioned a distance of 4.15 nm from each other. A relativistic stream of protons is directed at these slits. (a) If these protons have a relativistic kinetic energy that is equal to eight times their rest energy, then what is the distance a screen must be placed in front of the slits in order for the distance between the central maximum and the m

Use the data provided to calculate the gravitational potential energy of each cylinder mass. round your answers to the nearest tenth. 3 kg: kj 6 kg: kj 9 kg: kj

Polly is pushing a box across the floor with a force of 30 n. the force of gravity is –8 n, and the normal force is 8 n. which value could describe the force of friction if polly could not move the box?

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
