Some students fire a rocket of mass 0.150kg into the air. If at the top of it's flight it has a gravitational potential energy of 150J, What height did it reach?

There are 100 cm in every meter. If a measurement is 1.67 m, what is the measurement expressed in centimeters?

In a 400-m relay race the anchorman (the person who runs the last 100 m) for team A can run 100 m in 9.8 s. His rival, the anchorman for team B, can cover 100 m in 10.1 s.

TRUE or FALSE: We are able to see an object when it emits or reflects one or more visible light frequencies.

A 3 kg ball is rolling 2 m/s. How much kinetic energy does it have?

a canary sits 10 m from the edge of a 30-m-long clothesline, and a grackle sits 5 m from the other end. The rope is pulled by two poles that each exerts a 200-N force on it. The mass per unit length is 0.10 kg/m.

Which is a use of fiber optics?

When a positively charged conductor touches a neutral conductor, the neutral conductor will:

Definition of the rule E=mc^2

A 3.7 kg block is pushed along a horizontal floor by a force modifyingabove upper f with right-arrow of magnitude 25 n at a downward angle θ = 40°. the coefficient of kinetic friction between the block and the floor is 0.26.

When one object heats another, does the temperature increase of one object always equal the temperature decrease of the other object? Explain
