A notebook lasts 3.5 hours and requires 25 watts. Calculate the stored energy in the battery when it is fully charged?

Already have something to get, but unfortunately there are no solutions in our Ohysik book. In addition, I write an exam on Monday and want to find out if I'm ready.

25 * 3.5 = 87.5 wh

Thank you very much,

did not know it was that easy

What 25 watts per hour only? My graphics card already consumes 250 watts, how does that work?

Is just physics book lol

Can you also help me with the b)? :

calculate the time a notebook with this battery can be operated only 21W needed?

Then you did not understand what it is all about.

Still, I have more in my pear than you. That would make me think, bubiboy.

Fun was just a social experiment
