Answer:
<h3>Because one Coulomb of charge is an abnormally large quantity of charge, the units of microCoulombs (µC) or nanoCoulombs (nC) are more commonly used as the unit of measurement of charge. To illustrate the magnitude of 1 Coulomb, an object would need an excess of 6.25 x 1018 electrons to have a total charge of -1 C.</h3>

F = ma
4 = 40a
a = 0.1 m/s
v = u + at
-10 = 65 - 0.1t
t = 750s = 12.5 min
Current is defined as the rate of charge flowing a point every second. Having a current of 1 Ampere signifies 1 Coulomb is flowing in a circuit every second. It is measured by the use of an ammeter which is positioned in series to the component to be measured. The current in the problem is calculated as follows:
I = 2.0 x 10^-4 C / 5.0 x 10^-5 s
<span>I = 4 A</span>
1.) The rain will erode the concrete that's why sometimes you see marks in concrete surfaces.
2.) The streams, creeks, rivers, and etc, would overflow or flood and make new bodies of water but then when it dries up the water will dry up.
