Calculate the capacitance of a system that stores 9.4 x 10-10 C of charge at Q
50.0 V. Use C=
AV
O A. 1.9 x 10-11 F
OB. 4.7 x 10-8 F
O C. 5.3 x 1010 F
O D. 2.1 x 107 F

A. .

Explanation:

By definition of Electric Capacitance, the capacitance of the system (), in farads, is described by the following formula:

(1)

Where:

- Electric charge, in coulombs.

- Voltage, in volts.

If we know that and , then the capacitance of the system is:

The correct answer is A.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.
