What force (in N) must be exerted on the master cylinder of a hydraulic lift to support the weight of a 2100 kg car (a large car) resting on the slave cylinder

Complete Question:

What force (in N) must be exerted on the master cylinder of a hydraulic lift to support the weight of a 2100 kg car (a large car) resting on the slave cylinder ? The master cylinder has a 2.00-cm diameter and the slave has a 24.0-cm diameter

Explanation:

Given

--- mass

--- diameter of the large cylinder

--- diameter of the slave cylinder

To do this, we apply Archimedes' principle of buoyancy which implies that:

Where

Calculating the area of the master cylinder.

Calculating the area of the slave cylinder.

Substitute these values in:

Multiply both sides by

The force exerted on the slave cylinder (F2) is calculated as:

Substitute 20580 for F2 in

Hence, the force exerted on the master cylinder is approximately 142.92N

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
