Question

Power (P) is measured in watts using the following formula, where w is the work in joules and t is time in seconds.
P - w/t

If 5 watts of power are created over a period of 16 seconds, how much work did it take to create the power?

A- 11 joules
B- 3 joules
C- 21 joules
D- 80 joules

Answer 1

substitute p for 5 and then substitute t for 16
5 = w/16
multiply both side by 16 and then you get your answer

Answer 2

And that would be? sorry i have to hurry i have 10 minutes left on this quiz and still have like 6 questions

Answer 3

oh well it would be d

Answer 4

and if you have any more i will just give you a direct answer so you can finish the quiz

Answer 5

okay thanks so much one second its loading im in a hurry haha

Answer 6

ok

Answer 7

\[m = \frac{ y2 - y1 }{ x2 - x1}\]
Solve for y1

Answer 8

does it give you numbers to substitute

Answer 9

this is a type your own answer in

Answer 10

and no ma'am

Answer 11

i literally have no idea

Answer 12

im sorry

Answer 13

okay i got it next one uh
solve for L
P = 2L + 2w

Answer 14

A- l = 2p - w
B- l = 2/p - w
C- l = w/2 - p
D- l = p/2 - w

Answer 15

p-2w over 2 = L the answer might be L = p-2w over 2 but its the same thing

Answer 16

oh i think it would be c

Answer 17

says its wrong

Answer 18

I think its D

Answer 19

um i think its a i really dont know

Answer 20

Answer 22

i have no idea sorry
