a mass is connected by a light string that passes over a pulley of mass to a mass sliding on a horizontal surface. The coefficient of kinetic friction between the mass and the surface is 0.23. There is no slippage between the string and the pulley What is the magnitude of the tension that is acting on mass m

Use the table to answer question 22 23 and 24.

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

Agraduated cylinder contains 63.0 ml of water. a piece of gold, which has a density of 19.3 g/ cm3, is added to the water and the volume goes up to 64.5 ml. calculate the mass in grams of the gold that was added to the water. explain how you got your answer.
