Water pours into a fish tank at a rate of 0.3 cubic meters per minute. how fast is the water level rising if the base of the fish tank is a 2 meter by 3 meter rectangle?

Explanation:

As we know that the dimensions of the base of the tank is given as

now the base area is given as

now we know that volume of the liquid filled in the tank is given as

now we will differentiate it with respect to time both sides

here we know that

now we have

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
