Answer:
0.29 kg m² / s
Explanation:
Angular momentum is the product of moment of inertia and angular velocity.
L = I ω
For a solid cylinder, I = ½ m r².
L = ½ m r² ω
L = ½ (2.0 kg) (0.25 m)² (4.7 rad/s)
L = 0.29 kg m² / s
This is true. Gravity is constantly pulling on anything and everything (even light!), no matter how far away it is from another object.
Answer:
I think the SI unit of A is m^2/s
Ocean waves and sound waves are : mechanical wave. A and B aren't right at all. and C is wrong because they aren't electromagnetic.
Mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.
Hope this help
