Why is centrifugal force is a fake force?​

Physics
1 answer:
mash [69]3 years ago
5 0

Answer:

We say fictitious because the actual source of the centrifugal acceleration is somewhat indirect and the experience one has results from the unbalanced forces acting on the reference frame, not a force. Note, it is an acceleration not a force. For instance, imagine yourself on a swing.

Different between conventional and non conventional energy sources​
masha68 [24]

CONVENTIONAL SOURCE OF ENERGY:

The conventional sources of energy are generally non-renewable sources of energy, which are being used since a long time. These sources of energy are being used extensively in such a way that their known reserves have been depleted to a great extent.

At the same time it is becoming increasingly difficult to discover and exploit their new deposits. It is envisaged at known deposits of petroleum in our country will get exhausted by the few decades and coal reserves are expected to last for another hundred years. The coal , petroleum, natural gas and electricity are conventional sources of energy.

>Conventional sources of energy are not abundant, present in limited quantity, e.g. coal, petroleum, natural gas.

>conventional source have been in use for a long time.

>conventional source aren’t refill continuously. They are formed over a million years.

>Conventional source are called non-renewable fuel sources of energy.

> Conventional source are mostly used industrial and commercial purposes.

NON-CONVENTIONAL SOURCE OF ENERGY:

Energy generated by using wind, tides, solar geothermal heat and biomass including farm and animal waste as well as human excreta is known as non-conventional energy. All these sources are renewable or inexhaustible and do not cause environment pollution. More over they do not require heavy expenditure.

> Non-conventional sources of energy are abundant in nature, e.g. solar energy, wind energy, tidal energy, bio-gas from biomass etc.

>Non-Conventional source are development phase over the past few years.

>Non-conventional source are continuously fill by natural processes.

>Non-conventional source are called renewable source of energy.

>Non-conventional source are mostly used for household purposes.

Apart from height above ground, what does the amount of gravitational potential energy that an object has on earth depend on?
damaskus [11]

Answer:

Gravitational potential energy is due to the position of an object above Earth's surface. The object has the potential to fall due to gravity.

Explanation:

Gravitational potential energy depends on an object's weight and its height above the ground (GPE = weight x height). hope this helps you :)

Based on einstein's theory of gravity, if the sun and its mass were suddenly to disappear, earth would:________
g100num [7]

Based on Einstein's theory of gravity, if the sun and its mass were to suddenly disappear, earth would stay in its current orbit for a few minutes before taking off into space.

<h3>What would occur to our world if the sun were to suddenly vanish?</h3>

The Earth would be drawn to a new center of gravity if the sun disappeared. Earth's gravity would change, as would that of the rest of the solar system, and Earth would begin to drift into space since there would no longer be a steady source of energy from the sun. It is a foolish dream to think that life could exist without the sun forever. Humans could be able to survive for a while in some sort of base, such as a nuclear-powered dome.

The good news is that there wouldn't be many living things for the radioactive waste to endanger; however, there also probably wouldn't be any liquid water to cool the power system. All photosynthetic species, including plants and algae, would die if just the sun's light persisted.
