Conserved
Explanation:
The first law of thermodynamics states that energy in a systems is "conserved".
This law is the law of conservation of energy of energy. It states that:
"in an isolated system, energy can neither be created nor destroyed but it is transformed from one form to another".
- This simply shows that energy is conserved in an isolated system.
- In an isolated system, there is no exchange of energy with the environment.
- Also, energy is neither formed nor destroyed but transformed.

A or C , they both fit but i don’t know the right answer lol
Answer:7.93 m/s
Explanation:
Given
mass of ball
Mass of hanging ball
Length of string
Maximum angle turned
is the initial velocity of ball 1 and 0 is the initial velocity of ball 2
For Perfectly elastic final velocity of ball 1 and 2 is given by
where and are the velocity of 1 and 2 before collision
thus
By energy conservation on second ball we get
Kinetic energy=Potential Energy
thus
Answer:
1.55 h
Explanation:
Let the time to spend over dinner be t.
Since I need to spend 10.8 h for the whole trip, then I have 10.8 - t hours left to drive.
Speed = distance/time
The distance is 549 and maximum speed is 65 mi/h.
