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 red ladybug appears red in white light, red in red light, and black in blue light. Those would be the proper selections you'd need.
Note : Be careful with speed and velocity, even the formula is same that
1. If we would like to find the velocity, we must calculate the distance from initial to final,
,
2. If we would like to find the speed, we must calculate the total distance that travelled (
.
So, in this question, because it return back to its initial point so (delta)x = 0, so average velocity is 0 m/s.

Answer:
Centrifugal Force = 45.65N
Explanation:
Given the following data;
Mass, m = 80kg
Radius = 487m
Velocity = 60km/h to m/s = 60*1000/3600 = 16.67m/s
To find the centrifugal force;
Centrifugal Force = mv²/r
Substituting into the equation, we have;
Centrifugal Force = 80*16.67²/487
Centrifugal Force = 80*277.89/487
Centrifugal Force = 2223.12/487
Centrifugal Force = 45.65N
