When A Light Ray Hits A Boundary,,,,, it is called refraction.
Add the KE increase and the work done against friction.
The final velocity is twice the average, or 3.0 m/s
The final KE is (1/2)*25*3^2 = 112.5 J
The friction work done is 6*3.8 = 22.8 J
hope this is correct
Because the temperature causes it to go the physical change like if water is froze the temperate just caused it to go through another state of matter another example as if the ice got melted you would need high temperature to cause this change physically. Let me know if I help or if their is anything I can change for you to understand better
No thats false. If your trying to say is true that people BELIEVED that then yes its true people believed it but if your talking about that question then its false
Answer:
11.64225 m
Explanation:A = 45 m/s – 15m/s / 6s
A = 5m/s^2
