speed is the magnitude of velocity which is given as 90 km/hr and it does not change. only the direction change , the direction at any time is given by the tangent to the circle at that time and location.
from the diagram , at north side, the velocity is directed in west direction
Answer:
I believe the answer is that the light with the higher frequency refracts more than light with a lower frequency
Explanation:
Answer/Explanation:
The highest point of potential energy is A, when the ball rolls down the hill potential energy decreases and kinetic energy decreases, but the total energy is constant no matter what. This means the energy does not go away but instead is transferred to a different form.
A: most potential and least kinetic
B: losing potential gaining kinetic
C: losing more potential and gaining more kinetic
D: most kinetic and least potential
E: Gaining potential and losing kinetic
F: Gaining more potential and losing more kinetic
G: more potential than kinetic but not the most potential
