How much energy does a computer (P=130) uses in 10 hours?
Though you have not mentioned the unit of P, however, my best guess is that you meant 130Watt.
So,
A Watt is a unit of power,that is energy per unit of time,a watt is a Joule per second,130 W is then 130 Joules/s.
Therefore, in 10 hours it will use 130W*10hours*3600s,(an hour has 3600 seconds),that is 4680000Joules
Hope this helps :)
2A. How much mass-energy is there in a 130 g sandwich? 2B. If said sandwich was travelling at a speed of 0.6c, how much kinetic energy does it have? 2C. Protons in the LHC are accelerated until their mass-energy is 8TeV (8 x 10^ 12 eV). If protons have a rest mass of 938MeV/c^2 (9.38 x 10 ^8 ev/c^2), how fast are they going in terms of c? Your answer should include three digits that are not 9
