Part 1)
here we know that supply took 10 s to reach the ground
so here we will have
Part 2)
Here all the supply covered horizontal distance of 650 m in 10 s interval of time
so here we can say
Answer:
Explanation:
First we need to find the capacitance of the capacitor.
The capacitance is given by:
Where is the air permittivity, which is approximately 8.85 * 10^(-12)
The radius is 12/2 = 6 mm = 0.006 m, so the area of the capacitor is:
So the capacitance is:
The time constant of a rc-circuit is given by:
So we have that:
Answer:
Cars moving at constant speed on a circular race track
Explanation:
Stars and gas in the galactic disk moves in a roughly circular path about the center of the galaxy
