What type of power plant used heat from underground to make electricity
iren2701 [21]

That's called "<em>Geothermal</em>" energy.

"Geo ..." always means something about the Earth.

"Thermal ..." always means something about heat.

Geothermal energy is used in places where there's a lot of heat that's not too far under the ground, like in places above ancient volcanos.  

The system is built with pipes running deep down into the ground and then back up again, and then running water is pumped through the pipes.  The water picks up heat from down under and brings the heat up to the surface, where it can be used to heat homes and buildings, and turn steam turbines to generate electricity.

Geothermal is the MAIN source of energy in Iceland.

Helium gas at 20 °C is confined within a rigid vessel. The gas is then heated until its pressure is doubled. What is the final t
victus00 [196]

Answer:

586 K

Explanation:

Let P is the initial pressure.

Initial temperature, T₁ = 20°C = 293 K

Final pressure, P₂ = 2P

We need to find the final temperature of the gas.

The relation between the pressure and the temperature is as follows

P\propto T\\\\or\\\\\dfrac{P_1}{P_2}=\dfrac{T_1}{T_2}

Put all the values,

\dfrac{P}{2P}=\dfrac{293}{T_2}\\\\\dfrac{1}{2}=\dfrac{293}{T_2}\\\\T_2=2\times 293\\\\T_2=586\ K

So, the final temperature of the gas is 586 K.

An α-particle has a charge of +2e and a mass of 6.64 × 10-27 kg. It is accelerated from rest through a potential difference that
zzz [600]

Answer with Explanation:

We are given that

Charge on alpha particle=q=2 e=2\times 1.6\times 10^{-19} C

1 e=1.6\times 10^{-19} C

Mass of alpha particle=m=6.64\times 10^{-27} kg

Potential difference,V=1.97\times 10^6 V

Magnetic field,B=3.49 T

a.Speed of alpha particle=v=\sqrt{\frac{2 qV}{m}}

By using the formula

v=\sqrt{\frac{2\times 2\times 1.6\times 10^{-19}\times 1.97\times 10^6}{6.64\times 10^{-27}}

v=1.38\times 10^7 m/s

b.Magnetic force,F=qvB=2\times 1.6\times 10^{-19}\times 1.38\times 10^7\times 3.49=1.5\times 10^{-11} N

F=1.5\times 10^{-11} N

c.Radius of circular path, r=\frac{mv^2}{F}

r= \frac{6.64\times 10^{-27}\times (1.38\times 10^7)^2}{1.5\times 10^{-11}}

r=0.084 m

How much power does an Ox pulling a plow 20 m cross a field, exerting 120J of work over a period of 15 s?​
Aleksandr-060686 [28]

Answer:

8W

Explanation:

Given parameters:

Distance covered  = 20m

Work done  = 120J

Time  = 15s

Unknown:

How much power does the Ox exerts  = ?

Solution:

Power is the rate at which work is being done

  Power  = \frac{Work done }{time}  

 Power exerted by ox  = \frac{120}{15}   = 8W
