Why does the rate of change of potential difference between two capacitor plates decrease as the capacitor discharges?

Current, I , is related to voltage by Ohm's law, I=V/R . As the capacitor discharges, the current will decrease as less charge is "released" from the capacitor. From Ohm's law, we would expect lowe...

A rectangle has a total perimeter of 32cm with sides of length '3x' and 'x+8'. Solve for x.

3x + x+ 8 + 3x + x + 8 = 328x + 16 = 328x = 16x = 2

Differentiate cos(2x^3)/3x

Using quotient rule y = u/v - dy/dx = (v.du/dx - u.dv/dx)/v 2 .u = cos(2x 3 ) , a = 2x 3 . du/da = -sin(a), da/dx = 6x 2 . From chain rule, we know that du/dx = du/da . da/dx, so du/dx = -6x 2 sin(2x 3 ). We...
