A 1.5 m long fishing line rated as “20 lb test” that can stand a force of 20 lb (88.96 N) is attached to a sinker with a mass of 0.25 kg. What is the maximum speed that the sinker can be rotated without breaking the line? Someone please help

Contrast the force of gravity between these pairs of objects a 1 kg mass and a 2 kg mass that are 1 m apart and two 2 kg masses that are 1 m apart

What word chemical equation describes cavendish’s experiment with zinc?

Which statement is true? a) the work done to lift an object 6 meters is greater than the gravitational potential energy it gains. b) the work required to push an object is less than the work required to pull an object the same distance. c) the work required to raise an object to a height is equal to the gravitational potential energy the object gains. d) the work done against gravity to lift an object straight up is greater than the work required to roll it up a ramp.
