Which of these is true about the total energy in an object? can be destroyed cannot be constant cannot be transferred to other objects can be changed from one form to another

The correct answer is D. Can be changed from one form to another

Explanation:

In physics, the total energy in an object refers to the total quantity of energy that includes all the types of energies an object can have for example kinetic energy, electrical energy, gravitational energy, etc. All this energy according to the law of conservation is not created or destroyed, but instead, the total energy in an object changes from a form to another or it is transferred. For example, bulbs that contain electrical light transfer this energy to the objects in a room in the form of heat. Considering this, the statement that is true about the total energy is that it can be changed from one form to another.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

i don't know that i agree with that but what's the question ?
