A wheel rotates 10.0 radians in 2.5 seconds as it is brought to rest with a constant angular acceleration of -3.2 rad/s. What was the initial angular velocity of the wheel before the braking began?

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

What are similarities and differences of reflection, refraction, diffraction and absorption?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
