When Debbie pushes the first cart she is using an applied force. An applied force is created when someone or something pushes another thing using, of course, an applied force. Now, when the second cart is being pushed by the first cart, this is also an applied force. You can tell because the first cart is being pushed using forced and this causes the second cart to be pushed using some of the force that is being transmitted to the first cart.
Debbie exerts applied force on the first cart. The first cart exert applied force on the second cart.

Answer:
900 W.
Explanation:
Given that
Electric heater 1500 W
We know that power P given as
P= V I
So the total power of 120 V and 20 A circuit
P = 120 x 20
P= 2400 W
So the power new load P'
P'= Total system power(P)- Electric heater load
P ' = 2400 - 1500
P'= 900 W
So the answer is 900 W.
You are true, Stokey. The correct choice is<em> (c)</em>.
If you think about it a little bit more, you'll realize that "side to side" is also a horizontal motion.
Anyway, the question told us that we're only talking about 2 dimensions. Well, the The measurements in the 2 dimensions are the x and the y . If there were a z measurement, that would be the 3rd dimension.
Answer:
The friction of the piano and the weight
Explanation:
Answer:
2000J
Explanation:
work done = force * distance
Work done = 100 * 20
Work done = 2000J
