<span>The generation of electricity is done through the concert of energy conversion. A dam generating electricity from water flowing downhill is an example of how systems take advantage of energy flowing from high to low. Turbines play a huge part in generating electric power after the water passes through the spinning turbines and this water is left back to the river.</span>
Solution :
The electric field between two plates is given by
where
permitivity of free space
q = charge
A = surface area
It is given that :
the radius of the circular plates , r = 30 mm
the current, I = 0.43 mA
Therefore, Magnetic field can be found by
Density=mass÷volume
density=40.5÷15=2.7
B) scattering of light by air molecules
Air molecules have a significance size that enables the to scatter blue part of white liight from sun.
This produces the illusion that sky is blue
Answer:
Hey
muscuels should be your answer, with out gravity your musclues would become very weak. that's why astronauts on the ISS have to exercise daily.
