Two blocks with a mass of 2 kg collide in an elastic collision. The initial velocity of Block 1 is 10 m/s. Block 2 is traveling at 2 m/s in the same direction as Block 1. What is the final momentum and kinetic energy of Block 2? A final momentum: 2 kg x m/s, final kinetic energy: 1 J
B. final momentum: 20 kg x m/s, final kinetic energy: 10 J
C final momentum: 90 kg x m/s, final kinetic energy: 20 J
D. final momentum: 22 kg x m/s, final kinetic energy: 101 J​

b

explanation:

bc its just b

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
