Question

D?

Answer 1

@Vocaloid

Answer 2

good

Answer 3

c = q/v, you're given charge and voltage, find c

Answer 4

B

Answer 5

check your calculations again

(4*10^(-10))/ 250 = ?

Answer 6

A

Answer 7

perfect

Answer 8

A

Answer 9

because it would be the inverse

Answer 10

the question is talking about charge, potential energy is directly (not inversely) proportional to charge

Answer 11

U = kqq/r what would you need to increase q by to increase the potential energy by a factor of 16?

Answer 12

in order for U to be 16 times as much as it was before, what would we need to multiply the equation by?

Answer 13

4

Answer 14

keep in mind we are multiplying only one charge

if we take U = kqq/r^2 and multiply both sides by 16

16U = 16*kqq/r^2

which means we need to multiply one of the charges by 16 to increase the potential energy

Answer 15

so b

Answer 16

good

Answer 17

D

Answer 18

keep in mind if KE is decreasing what must be happening to the speed?

Answer 19

I know its either c or d

Answer 20

So c because it is slowing down

Answer 21

good

Answer 22

D

Answer 23

well done

Answer 24

B

Answer 25

i multiplied both values given to get the amount of work that is done

Answer 26

yeah that's right

Answer 27

C

Answer 28

close but not quite, it's not two point charges that are being separated

Answer 29

OH D

Answer 30

well done

Answer 31

could you explain this to me, I dont understand

Answer 32

it's a units question, what are the units of electric potential?

Answer 33

C

Answer 34

good so C = your answer
