110V x 3.2A = 352W

352W x 5h = 1,760Wh

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.

Calculate the speed for a car that went a distance of 125 kilometers in 2 hours time.
laila [671]

The speed of the car was exactly 125 km per 2 hours.

In a more familiar unit,  125km/2hr = 62.5 km/hr.

If all the mechanical energy is converted into heat that stays in the water. How much of a rise in temperature occurs in a 90.0
vodka [1.7K]

If all the mechanical energy is converted into heat that stays in the water. 0.21˚C rise in temperature occurs in a 90.0 m waterfall.

The total kinetic and potential energy is known as mechanical energy. According to the principle of mechanical energy conservation, mechanical energy is constant in an isolated system when only conservative forces are acting on it.

The mechanical energy of water is converted into heat energy.

P.E = mgh = m x 9.8 x 90.0

P.E = 882 m.

Let rise in temperature θ

Heat energy = mass × specific heat × temperature change

Heat energy = m x s x θ

specific heat = 4186 J/(Kg *˚C)

m x s x θ =  882 m

m x 4186 x θ = 882 m

θ = 0.21˚C.
