Answer & Explanation:
Relative age is the age of a rock layer (or the fossils it contains) compared to other layers. It can be determined by looking at the position of rock layers. Absolute age is the numeric age of a layer of rocks or fossils.
Momentum = mass times velocity
mass = 2500kg
velocity = 4.92 m/s
Therefore momentum = 2500 x 4.92
= 12300 Kg m/s
Speed = (distance covered) / (time to cover the distance)
Speed = (121 m) / (30 sec)
Speed = 4.03 m/s (about 9 mph ... pretty slow for a bobsled)
Nuclear power emits radiation.
Answer: Clouds are evaporated sea water. You should be asking "Why does the gravity on Earth pull us down and not evaporated water.
Explanation:
Answer:
Because of their mass
Explanation:
Clouds are made of water right ? so you are asking why they don't fall down if air is lighter than water .
The two biggest reasons the clouds stay in the sky are
1. Small Drops
2. Wind
Small drops of water fall more slowly than big drops, as the drops of the clouds fall thought the air, the air pushes back to them, because Small drops has less mass than large drops, clouds can only contain small drops of water.
