Answer:
The work done depends upon the <u> Force</u> applied and <u>Displacement</u> produced.
Explanation:
Definition: Work is said to be on a body only if a force acting on it causes a displacement in its direction
.
In other words we can say it is the product of force and displacement
Formula:
Unit:
The unit of work is Joule.
So, work depends on the force applied and the displacement caused by the applied force.
If force is applied and there is no displacement, then work is 0
.
Example: Pushing a wall does no work.
Work is positive if force applied and displacement is in same direction.
Work is negative if force applied and displacement is in opposite direction.

Hope this helps. Have a great day.
Answer:
Different types of hot or cold items can be stored in a thermos and power cannot enter or exit the system when the thermos lid is tightly closed
Explanation:
Closed systems are those that do not interact or do not exchange energy with the environment that surrounds them, that is why internal temperatures and conditions are maintained.
The human body is an open system, that is, it would be the opposite of the thermos since we constantly exchange energy with the environment through sweating, emission of gases, urine, feces, and the ingestion of food.
Thermoses are systems specially created to maintain a medium, it will be maintained if its lid is hermetically closed to prevent heat leakage or entry in situations of cold fluids.
