Thenks and mark me brainliest :)
Hello,
I believe they are a lever and a wedge.
I hope this helps!
1. U = Q + W
U = -500 + 1000
U = 500 J
2. The first law of thermodynamic is about the law of conservation of energy where energy in should be equal to energy out.
3. It is the windmill that does not transform energy from heat to mechanical instead it is the transforms the opposite.
4. In a heat engine, work is used to transfer thermal energy from a hot reservoir to a cold one.
5. 5.00 × 10^4 J - 2.00 × 10^4 J = 3.00 × 10^4 J
6. To increase the work done, we raise the temperature of the cold reservoir.
Answer:
a) 
b) 
Explanation:
From the exercise we know that
From dynamics we know that the formula for average velocity is:
a) For the three intervals:
b) The average velocity for the entire motion can be calculate by the following formula:
