Question

Ok, this is sort of science & math soo....

Calculate power using the following variables. Force= 50 N, Distance= 10 m, Time= 25 seconds. What is the power?

Answer 1

answer choices

10 watts
20 watts
50 watts
100 watts

I really dont get this question!

Answer 2

I'm doing the same thing, and am stuck on step 3... @levinelevine should help: :-)

Three steps...

step 1: multiply newton by meter to get joules = 50 J

step 2: Divide energy into time and you will get the rate of power (Watts) that is used.
50(J) / 25(S)=2(mW)/0.002(W)

step 3: ?

Answer 3

20 watts, this is physics not chem dude

Answer 4

so step 3 was.... multiply by 10000

Answer 5

F*distante=work, WOrk/time=power. watt =newton*m/t

Answer 6

nwetons*m=joule;joule/s=watt

Answer 7

yes.ok... @wseekay physics and chem are substantially different by the way! :-)
