Aski tow operates on a slope of angle of length .the rope moves at a speed of and provides power for riders at one time, with an average mass per rider of
.
q)
estimate the power required to operate
thetow.

The power required to operate the tow is 30817.76 watts.

Explanation:

It can be assumed that,

The mass of the rider, m = 71 kg

Slope with the horizontal,

No of riders are 53

Speed of the rope, v = 11.7 km/h = 3.25 m/s

We need to find the power required to operate  the tow. It is equal to the work done per unit time or it is equal to the product of force and the velocity.

F is equal to the weight of 53 riders as,

P = 30817.76 Watts

So, the power required to operate the tow is 30817.76 watts. Hence, this is the required solution.

i'm thinking more like energy

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.
