Answer:Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
D, because you are pulling on the rope. :)
Answer:
The critical angle for a diamond in air is 24 degrees, while the critical angle for glass is 41 degrees.
Explanation:
Rays exiting the material at an angle less than the critical angle will be refracted, and rays incident on the interface at greater than the critical angle will be totally reflected back inside the material.
The answer would be -pitch-
Hope this helps
Have a great day/night
