Two 1.60cm×1.60cm plates that form a parallel-plate capacitor are charged to ± 0.711nC . What is the potential difference across
lina2011 [118]
The surface charge density:
S(igma) = Q / A
A = 1.6 * 10^(-2) * 1.6 * 10^(-2) = 2.56 * 10^(-4) m²
The electric field:  E = S / E(psilon) o 
E = 0.711 * 10^^(-9) / ( 2.56 * 10 ^(-4) * 8.85 * 10 ^(-12) ) = 
= 0.3138 * 10 ^6 = 3.138 * 10^5 V/m
a ) Δ V = E d
Δ V = 3.138 * 10^5 V/m* 1.2 * 10^(-3) m = 376.56 V
b ) When d = 2.40 mm:
Δ V = 3.138 * 10^5 V/m * 2.40 *10^(-3) m = 753.12 V

I need help figuring out 121+2=9(-6-7P)+4P
Alex_Xolod [135]
Hi,


Work:


Equation;

121 + 2 = 9( - 6 - 7p) + 4p

First add up numbers and distribute 9 over parenthesis.

123  =  - 54 - 63p + 4p

Second: collect like terms.

123 =  - 54 - 59p

Move variable 59p to left side and change its sign.

59p + 123 =  - 54

Then move constant 123 to right side and change its sign.

59p  =  - 54 - 123

Calculate the difference.

59p =  - 177

Divide both sides of equation by 59.

p =  - 3


Hope this helps.

Negitive 8 over 2 divided by 6 over negitive 3 = ??????
solmaris [256]

when you didve fractions flip the second one over and multiply

 so -8/2 divided by 6/-3 will become

-8/2 times -3/6

then multiple straight across so -8 x -3 = 24

over 6 time 2 = 12

 so you get 24/12 which equals 2

PLEASE HELP!!! What is the slope parallel to 5x + y = 3, please show me step by step, will give the brainliest for this answer.
Andreas93 [3]

Answer:

-5

Step-by-step explanation:

First, put the equation into the form y = mx +b (where m is the slope and b is the y-intercept)

This would look like:

5x + y = 3\\y = -5x + 3

This means the slope is -5.

Parallel lines always have the same slope, so the slope of the parallel line is also -5
