Questions in this quiz (4)
1A wooden block of mass 0.60 kg is on a rough horizontal surface. A force of 12 N is applied to the block and it accelerates at 4.0 m.s^–2.
What is the magnitude of the frictional force acting on the block?- AA 2.4 N
- BB 9.6 N
- CC 14 N
- DD 16 N
2A horizontal force of 90N is used to push a box across a horizontal floor. The frictional force on the box is 50N.
What is the gain in kinetic energy of the box when it is moved through a distance of 6.0m?- AA 240 J
- BB 300 J
- CC 540 J
- DD 840 J
3A positive charge experiences a force F when placed at point X in a uniform electric field.
The charge is then moved from point X to point Y.
Distances r and s are shown on the diagram.
What is the change in the potential energy of the charge?- AA decreases by Fs
- BB increases by Fs
- CC decreases by Fr
- DD increases by Fr
4A submarine is in equilibrium in a fully submerged position.
What causes the upthrust on the submarine?- AA The air in the submarine is less dense than sea water.
- BB The sea water exerts a greater upward force on the submarine than the weight of the steel.
- CC The submarine displaces its own volume of sea water.
- DD There is a difference in water pressure acting on the top and bottom of the submarine.
