The image above shows two opposite forces acting on a rope. what can we say is true if the forces on each side of the rope is doubled to 150 newtons? a) it cannot be determined without knowing which man is stronger. b) the forces are not balanced, because one man is standing taller than the other. c) the forces are balanced. but, the forces acting on the rope have increased and the rope’s motion is affected. d) the forces are balanced. thus, there is no change in forces acting on the rope and the rope’s motion is not affected.

Find the magnetic field a distance r from the center of a long wire that has radius a and carries a uniform current per unit area j in the positive z direction.

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
