Answer:
Explanation:
The equation for this is the one for the Law of Momentum Conservation which says that the momentum before the collision of the balls has to be the same after the collision because momentum cannot be created or destroyed. For us in particular:
and filling in:
[(4.0)(6.0) + (2.0)(0)] = [(4.0 + 2.0)v] and
24 + 0 = 6.0v and
24 = 6.0v so
v = 4.0 m/s to the right
Answer:
You will discover that at high altitude, there is cold and the opposite is experienced when you go deep down the sea. However, the reason elevation affects climate and temperature gets colder is this. As you go higher up, the atmosphere experiences less pressure.
Explanation:
25 x 10^-5
= 0.00025
25 cm
= 0.00025 km
Answer:
m = 1.531kg
Explanation:
F = mg
m = F/g
m = 15/9.8 = 1.531kg (Approximately)
Yes, this is accurate. While "dark matter" might exist, it is still more of a theory, it is not yet defined properly. As far as we truthfully know, the entire universe is just matter and energy.
