Len [333]

Answer:

D. Nothing will happen; the seesaw will still be balanced.

Explanation:

D. Nothing will happen; the seesaw will still be balanced. Since both toruqes or momentums respect to the center have changed in the same amount (one-half their original distance) the seesaw will remain balanced, if the children change distance in a different amount then it will be out of balance

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.

two objects each weighing 2kg are lifted through the same distance in 4s and 1s respectively. which scenario requires more work?
Shalnov [3]

i believe it would be the same because time doesn't matter when calculating total work done.

Work=FxD

F=force

D=distance

A ball of mass 0.3 kg is released from rest at a height of 8 m. How fast is it going when it hits the ground? (Gravity being equ
docker41 [41]

Answer:

Explanation:

Mass doesn't matter here because when something is falling, gravity plays fairly; an elephant falls at the same rate of acceleration as does a feather. What DOES matter is everything pertinent to the y-dimension of free-fall:

a = -9.8 m/s/s

v₀ = 0 (since the ball was held before it was dropped)

v = ??

Δx = -8 m (negative because the ball drops this far below the point from which it was released).

Putting all this together in one equation:

v² = v₀² + 2aΔx and filling in this equation:

v² = (0)² + 2(-9.8)(-8) and

v² = 156.8 so

v = 12.5 which rounds to 13 if you're using 2 sig figs, and rounds to 10 if you're only using 1 (which you should be, according to the way the numbers have been given in this problem)
