1. ## +rep for just confirming if i'm right in a science problem

+rep for correcting me pls lol

What is the current in an electric stove element that creates 150J of heat at 240V over a 5 minute period?

G: 150J (E), 240V (V), and 5m (300s) (t)

R: Using the equation for current, I=Q/T, I know that I have the variable t, which is 300s, but not the others.
However, I can rearrange the equation of V=E/Q to Q=E/V to figure out my variable Q, my last variable needed to find the current (I)

A/S: Q=150/250
= 0.625C

I=0.625/300
= 2.083x10^-03

S: Therefore the current is 2.083x10^03.

The number does not look right at all but can someone tell if I'm doing anything wrong?

Is this physics? I came here to take a look and immediately hated my life because of what I was reading. I'm in physics in hs right now and I hate it. I'll attempt to look at it anyways

Ummmmmmmmm I think, LOL, I'm literally just skating by this unit with no idea what's going on, so I think so-- haaaaaaaahaaaa

Im sorry

Holy fuck those questions are exactly mine OMG

Well, helpful nontheless, so rep for ya

haha sweet! When it comes to science questions usually if you google the exact question there are answer online in some fashion. Sometimes they're in pdf form and a whole homework lesson is written out!

8. yea you are correct. This seems like physics 1 questions which used to be a problem at first for me. However, once you pass physics 3 (magnetism and elctromagnetics) this is really simple.
