Explanation:
Given that,
Altitude 
We need to calculate the radius
Where, R = radius of the earth
h = radius of altitude
Put the value into the formula
(a). We need to calculate the period of the orbit,
Using formula of period
(b). We need to calculate the speed of the satellite
Using formula of speed
Put the value into the formula
(c). We need to calculate the acceleration of the satellite
Using formula of acceleration
Put the value into the formula
Hence, This is the required solution.
Answer:
h = 1.22 m
Explanation:
Given:
Pressure in the vein = 12200 Pa
Specific gravity of the liquid = 1.02
now,
the pressure due to a fluid is given as:
P = pgh
where,
P is the pressure,
ρ is the density of fluid = specific gravity x density of water = 1.02 x 1000 kg/m³
ρ = 1020 kg/m³
g is the acceleration due to the gravity = 9.81m/s²
h is the height
thus,
h = P/pg =
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.
