Atemperature of a 50kg block increases by 15 degrees celsius when 337,500 j of thermal energy are added to the block. what is the specific heat of the object? show your work

Akg a of 55 m at an of 11 ? . if is at 98 km/h,be ?

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)

Efficiency is the ratio of to for a system a)power in to power in b)power in to power out c) power out to power out d) power out to power in
