8. The amount of water pressure you experience while swimm your weight the area of the pool. the volume of the water in the pool. how deep you are in the water. Which of the following is NOT

State the magnitude and direction of the total force on the object (puck, car, ball, and boat

Objects 1 and 2 attract each other with a electrostatic force of 72.0 units. If the distance separating objects 1 and 2 is changed to one - halved the original value (i. e, halved), then the new electrostatic force will be

Two rocks collide in outer space. Before the collision, one rock had mass 11 kg and velocity ‹ 4250, - 2950, 2500 › m/s. The other rock had mass 6 kg and velocity ‹ - 700, 2150, 3700 › m/s.

A 0.43 m long and 0.43 m wide loop is moved at a constant velocity of 0.15 m/s into a perpendicular constant magnetic field of 0.31 T. Calculate the magnitude of the induced voltage in the loop.

given that a car's distance from a stop sign t seconds since it started moving is represented by d=t2-2t determine the car's average speed over each interval of elapsed time

A ball hits a wall. What is true about the magnitude of the force experienced by the ball compared with the force experienced by the wall? OA. The ball experiences more force than the wall. OB. The ball experiences less force than the wall.

A swimmer jumps from a waterfall thats is 8.5 m high from the lake below. How fast must he run horizontally to dive 2.5m away from the base of the waterfall?

What happens (as far as energy goes) when a molecule of gas strikes the wall of a container?

The boom of a fire truck raises a fireman (and his equipment - total weight 280 lbf) 60 ft into the air to fight a building fire.
