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.

if a certain car, going with speed v1, rounds a level curve with a radius r1, it is just on the verge of skidding. if its speed
schepotkina [342]

Answer:

The correct answer is 4R1

Explanation:

According to the given scenario ,the radius of the tightest curve on the same road without skidding is as follows:

As we know that

Centeripetal Acceleration is

= v^2 ÷ r

In the case when velocity becomes 2 times so the r would be 4 times

So, the radius of the  tightest curve on the same road without skidding is 4R1

Consider Compton Scattering with visible light.A photon with wavelength 500nm scatters backward(theta=180degree) from a free ele
JulijaS [17]

Answer: 4.86(10)^{-12}m

Explanation:

The Compton Shift \Delta \lambda in wavelength when photons are scattered is given by the following equation:

\Delta \lambda=\lambda' - \lambda_{o}=\lambda_{c}(1-cos\theta) (1)  

Where:  

\lambda'=500 nm=500(10)^{-9} m is the wavelength of the scattered photon

\lambda_{o}  is the wavelength of the incident photon

\lambda_{c}=2.43(10)^{-12} m is a constant whose value is given by \frac{h}{m_{e}.c}, being h=4.136(10)^{-15}eV.s the Planck constant, m_{e} the mass of the electron and c=3(10)^{8}m/s the speed of light in vacuum.  

\theta=180\° the angle between incident phhoton and the scatered photon.  

\Delta \lambda=2.43(10)^{-12} m (1-cos(180\°)) (2)

\Delta \lambda=4.86(10)^{-12}m (3)  This is the shift in wavelength

Last week we investigated the black hole at the center of our galaxy, with massMX= 8.5×1036kg. An object whose size is on the or
swat32

Answer:

d=2.38*10^{13}m

Explanation:

We know the mass of the hole, so we define as,

M_x= {8.5*10^{36}}kg

For which centripetal force is equal to gravitational force

\frac{mv^2}{r}=\frac{GMm}{d^2}

Angular velocity is equal to v/r,

w^2r=\frac{6.67*10^{-11}*8.5*10^{36}}{d^2}

As r=1 and w=1, we clear to d,

d^2=5.6695*10^{26}m

d=2.38*10^{13}m

What is the term for the depth of the water needed to float a boat?
mina [271]
<span> The term for the depth of the water needed to make a boat afloat is called the draft of the boat. It can be measured as the distance from the water surface down the lowest point of the vessel. It can be imagined as the submerged portion of the boat during navigation.</span>

A car's acceleration is 3m/s2. If the car started at rest and it only took 10s for the car to reach this acceleration, what is t
Grace [21]

Answer:

30m/s

Explanation:

From law of motion equation

Vf= Vi + at

Where Vf= final velocity

Vi= initial velocity=0(the car started at rest)

a= acceleration= 3m/s2

t= time= 10s

Then substitute into the equation to get the final velocity.

Vf= 0+(10×3)

Vf= 30m/s

Hence, the car's final velocity is 30m/s
