Answer: A
Explanation: Any short-duration exercise that is powered primarily by metabolic pathways that do not use oxygen. Examples
of anaerobic exercise include sprinting and weight lifting.
Answer:
Explanation:
at collision, m has a velocity of √2gR
The center of mass of the system has a velocity of
m(√2gR) + 3m(0) = (m + 3m)v
v = ¼√2gR
The stationary mass (3m) will depart at twice the system center of mass velocity
v(3m) = ½√2gR ANSWER B
The relative velocity before the collision will be the negative of the relative velocity after the collision.
v(m) = ½√2gR - √2gR = -½√2gh ANSWER A
m will rise to a height of v²/2g = (-½√2gR)²/2g = 0.25R
Answer:
0.50 m tall
Explanation:
To see the full height of the child the height of the mirror should be half of the height of the child
As it id given that the height of the child is 1 meter so the height of the mirror is 
As it is a rule that to see the full any object the height of the mirror should be half of the height of the object
I think it would be atomic energy, which would most likely be in very short waves to affect the protons.
