7. Determine the amount of potential energy of a 5.0kg book that is moved to three different

shelves on a bookcase. The height of each shelf is 1.0 m, 1,5 m, and 2.0 m.

A 1170-kg car is held in place by a light cable on a very smooth (frictionless) ramp, as shown in the figure (Figure 1). The cable makes an angle of 31.0 ∘ above the surface of the ramp, and the ramp itself rises at 25.0 ∘ above the horizontal.

The electric field in a 3.0mm*3.0mm square aluminum wire is 1.0*10-2 V/m. What is the current in the wire?

In a physics laboratory experiment, a coil with 200 turns enclosing an area of 11.8 cm^2 is rotated during the time interval 4.

Pressure can affect the density of Solids Liquids Gases Metals

Onur drops a basketball from a height of 10m on Mars, where the acceleration due to gravity has magnitude of 3.7 m/s^2. We want to know how many seconds the basketball is in the air before it hits the ground. We can ignore air resistance.

Beth made the chart shown. A 2-column table with 1 row. The first column labeled X has entries Wall clock, T V remote control, Portable music player. The second column labeled Y has entries Refrigerator, Table lamp, Hair dryer.

Which sentence states Newton's third law? If two objects collide, each object exerts a force in the same direction as the other. If two objects collide, each object exerts a force equal to and in the opposite direction of the other.

Why did the chicken cross the road.

A 98.1 kg horizontal circular platform rotates freely with no friction about its center at an initial angular velocity of 1.69 rad/s. A monkey drops a 9.29 kg bunch of bananas vertically onto the platform.
