<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>
Answer:
14 seconds
Explanation:
Distance covered by sports car is measured with 21*t where t is time.
Distance covered by police is measured with at^2/2(t-time, a-acceleration) as it doesnt have starting velocity. If the distances are equal(police catches sport car)
then we have 21t=3/2*t^2 Solving this equation we get t=14 & t=0;
excluding the starting point we have 14 seconds

Answer:
Convection
Explanation:
Three methods of heat transfer they are conduction, convection, and radiation.
The conduction heat transfer take places in the solid materials.
Convection heat transfer take place in the moving fluid like air,water etc.
Radiation heat transfer take place in the form of electromagnetic waves.Every body which have temperature above absolute zero ,emits radiation.
Therefore the answer is --
Convection
