1) The angular size of the Moon and Sun need to be very close.
2) Alignment of the Sun, Moon and Earth in that order (or reverse)
3) For you to be at the exact spot where the shadow of the moon passes.
Yes, energy is required to produce any sound. When an object vibrates, it transfers energy to the surrounding air molecules, creating sound waves that we hear. Whether it's a voice, a musical instrument, or a machine, energy is needed to initiate and sustain these vibrations.
A bicycle does not produce energy on its own; instead, it converts the rider's pedaling motion into mechanical energy to propel the bike forward. The energy required to pedal a bike comes from the rider's muscular effort.
The energy usage per kilogram varies depending on the specific energy source or process in question. For example, the energy required to produce a kilogram of steel is different from the energy used to produce a kilogram of rice. It is important to consider the specific context or application when calculating energy usage per kilogram.
Nuclear energy has the potential to produce the most energy among alternative sources due to its high energy density and efficiency. Wind and solar energy are also significant sources of renewable energy but may be limited by factors such as weather conditions and size of installations.
When certain conditions are met in a system, such as increasing the height or mass of an object, more potential energy is stored in the system. This means that the system has the capacity to do more work or produce more energy when those conditions are present.
A Star will produce its own light, through the nuclear fusion of hydrogen, which releases vast amounts of energy. Planets are not large enough for the required conditions to occur for this reaction, so they don't produce energy in this way.
Not exactly, but there are enormous reserves of nuclear fuel available. This is because a small amount of uranium, for example, or of deuterium, produce a large amount of energy.
The nuclear fission of the isotope 235U, with thermal neutrons, release 202,5 MeV per atom - an enormous quantity of energy.

One horsepower (HP) is equivalent to about 746 watts of mechanical power. To produce one horsepower of mechanical energy, the electrical energy required depends on the efficiency of the motor converting electrical energy to mechanical energy. For example, if a motor operates at 90% efficiency, approximately 830 watts of electrical energy would be needed to produce one horsepower. Thus, the electrical energy required varies with the efficiency of the system used.
Yes they can but the energy required to produce oil is out of proportion to the energy we will receive

Gas generators are used to produce enormous amounts of energy. Therefore, they are used when there is need for such energy in cases like rockets launch or other similar take offs.
