A block of copper with mass 0.500 kg is heated to 400. degrees Celsius from 290. degrees Celsius. The specific heat capacity of copper is 387 J/ (kg*C°). The heat absorbed by the copper block is 7.74 E5 J
7.74 E4 J
5.61 E4 J
2.13 E5 J
2.13 E4 J

2.13 E 4 J

Explanation: Heat absorbed = mass * specific heat capacity * change in temperature

= 0.5 * 387 * (400 - 290) J

= 0.5 * 387 * 110 J = 21285 J = 2.13 E 4 J

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
