Energy <span>due to position is potential energy</span>
<span>a) M is the big one
m is the little one
v is the speed of each of them when they impact
V = speed of mii after collision
Conservation of momentum
Mv – mv = mV
Conservation of energy
1/2Mv^2 + 1/2mv^2 = 1/2 mV^2
This pair simplify to give
M = 3m
V = 2v
So m = 0.21kg
and h = 4 . 2.7 = 10.8 m</span>Source(s):<span>Old teacher</span>
I believe the answer would be A that you move the lever away from you to load the rifle (I know since I had such a rifle). This action places a shell into the firing chamber so that it is ready to fire so makes it convenient to re-load unlike where a shell must be placed in the chamber by hand each time such as is the case with many 0.22 rifles.
Answer: The sun’s radiation consists of small, massless packets of energy called photons. They travel seamlessly through space; whenever they strike any object, the object absorbs photons and its energy is increased, which then heats it up.
Explanation:
