I would say the answer is 3 because by falling technically the ball would be kind of moving in the air. Plus potential energy is when for example a soccer ball isnt moving
F=nmv
where;
n=no. of bullets = 1
m=mass of bullets=2g *10^-3
V=velocity of bullets200m/sec
F=1
loss in Kinetic energy=gain in heat energy
1/2MV^2=MS∆t
let M council M
=1/2V^2=S∆t
M=2g
K.E=MV^2/2
=(2*10^-3)(200)^2/2
2 councils 2
2*10^-3*4*10/2
K.E=40Js
H=mv∆t
(40/4.2)
40Js=40/4.2=mc∆t
40/4.2=2*0.03*∆t
=158.73°C
Answer:
the answer is the spinning of the moon lets us see different amounts of light
Explanation:
you wanna know why uh yes ok lets cut to the magic so when the moon.
[Any unit of mass] divided by [any unit of volume]
is a perfectly good unit of density.
Probably the most widely used unit is (gram / cubic centimeter).
But it could just as well be (metric tonne / cubic parsec) .
