Yes, heat can be used as a form of energy to perform work.
It is what will need to perform work! The cell in our body need nutrient and energy to perform wook
work is not by the force . work is done by the body against or for the force. since work is force x displacement it will be 265x2.40 =636 N .and since work is done for the gravity work done will be -ve so it will be -636 N .
The key factor that enables objects to perform work is energy.
That is called the "efficiency" of the device.
In science, energy is defined as the capacity to perform work.
Scientist describe energy as ability to do or perform work.
Energy is the ability to do work. The more energy something has, the more work it can do. Energy is required to perform any kind of work, and the amount of energy available determines the capacity to do work.
Energy is the capacity to do work. In order for force to do work, there must be a transfer or transformation of energy within a system. So, energy is needed for force to perform work.
Efficiency.
The answer is efficiency.
