an unknown metal with a mass of 135.0 grams was heated in boiling water and then allowed to come to thermal equilibrium with 80.0 grams water that was 22.0 degrees celsius before the metal was added. the ending temperature of the water was found to be 41.0 degrees celsius. what was the temperature change of the metal and water?

what was the answer?

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.

not too sure thinking all accelerations are pointed down
