It depends on what you consider necessary. Leaving your computer on will not hurt a thing. The internet is contrived of millions of computers that stay on all the time. If you are looking to conserve energy, then it would be necessary.
Well he has the spiritual energy to, but he doesn't have the relentlessness necessary to do such a thing. Sooo no. He can't.
To calculate energy, you can use the formula: Energy (Joules) = Power (Watts) * Time (seconds). This formula considers the power input over a certain period of time to determine the total energy output. Alternatively, you can also calculate energy using mass and speed with the formula: Energy (Joules) = 0.5 * Mass (kg) * Speed (m/s)^2.
Any animal (Including human beings). Plants live and need a source of energy but they dont "eat." They use photosynthesis.
It is not necessary that our life forms on planet earth require energy only from sun. Plants can photosynthesize and survive under artificial light. The only thing is we don't have an alternative source of energy.
No, energy will transfer between any adjacent bodies, moreover, a medium is not necessary for energy to transfer between objects at all. That would be a little thing called radiation.
No. Specific heat capacity (c) is used in to calculate energy when matter is not undergoing a phase change [Q = mc(delta)T]. Heat of fusion (HF) is used to calculate energy when matter is either melting or freezing [Q = m(HF)].
necessary means if do you think you should be doing that or do you feel that your doing the right thing "do you feel that's necessary"
The same thing as energy is the capacity to do work or cause change.
A device called a calorimeter measures thermal energy by determining the amount of heat released or absorbed during a chemical reaction or physical change. It can also calculate the specific heat capacity of a substance.
Because its an important thing
by eating you get energy from the food
