A1.00-kg iron horseshoe is taken from a forge at 900∘c and dropped into 4.00 kg of water at 10.0∘c. assuming that no energy is lost by heat to the surroundings, determine the total entropy change of the horseshoe-plus-water system.

Explanation:

Given:

We have,

Now the final temperature of the system assuming that no heat is lost to the surrounding:

Now the change in heat energy:

Hence the change in the entropy of the system:

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.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
