Answer:
Explanation:
When coin is at a height and rest, it only has potential energy( by the virtue of its position). While the coin is falling its potential energy changes into kinetic energy. This means that its potential energy is decreasing and kinetic energy increases. just before its hits the ground kinetic energy is maximum and potential energy becomes zero.
When it hits the ground all its kinetic energy is converted into heat.
<span>The force that opposes the movement of an object through
water is called drag. This is a type of frictional force. This force normally
depends on the density and the viscosity of the fluid in question. The liquid
which has more density and more viscosity or stickiness will produce a greater
amount of drag force on an object than a fluid that is less dense and less
viscous in nature. River water normally
has less drag than that of sea water. </span>
Answer
For conductors in series 1/2+1/3+1/6=1
And in parallel 2+3+6= 11
For the combination of series and parallel you get 2+11=13
