If we decrease the amount of force applied to an object, and all other factors remain the same, the amount of work completed will decrease.

Option A

Explanation:

When force pushes the body to move, it shows that work acts on the object. Work is the measure of transfer in energy when a force (F) pushes the object at a distance (d). After completing the task, energy is transferred from one energy storage device to another, therefore, energy transfer = work done.

The formula for work done is given as follows and expressed in joules (J),

From the above the equation, it clearly shows that work is directly proportionate to force. When keeping the other factors as constant, decrease in work leads to decrease in force also and vice versa.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
