A "8" grams box is pushed with a force of 100 N for 1m whereas opposing force is 10 N. A) Find the net work done on the box. B) Find the total work done by considering work done by each force. "

A)   Wn = 90J

B)   W1 = 100J

     W2 = 10J

Explanation:

A) The net work done on the box is calculated by using the following formula:

    (1)

F1 = 100N

F2 = 10N

d: distance on which the box is moved = 1m

You replace the values of the parameters in the equation (1):

The net work on the box is 90J

B) The total work done by each force is:

The first box does a work of 100J and the second force does a force of 10J

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.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
