Find the change in internal energy, AU, if Q = 2.5 Joules and W = -30.5
Joules. *

33 J

Explanation:

Using first law of thermodynamics

Q= W + U

2.5 = -30.5 + U

U = 2.5 + 30.5

U = 33 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.
