Rocks are made up of different compounds. Gases like nitrogen, oxygen and water vapour and some non-metallic oxides react with these compounds to form new compounds and then break down into fine particles, due to breaking of bonds between the atoms, caused by the reaction of gases.This leads to break down of rocks into fine particles
Answer:
Actual velocity of the ping-pong ball= 5 m/s
Explanation:
velocity of ping pong ball because of the shot gun= 4 m/s North
velocity added to the ping-pong ball due to the wind=3 m/s
These velocities are perpendicular to each other. so we use Pythagoras theorem to find the resultant velocity of the ping- pong ball
so the actual velocity of the ping-pong ball =V= √4²+3²
V= √25
V= 5 m/s

The answer is liter hope this helped :)
Volume= h*l*w
2*3*2=12cm
You're answer is 12cm. Hope it helps!
The density of the liquid is 0.2 g/mL.
The mass of the liquid is 6 g.
The volume of the liquid is 30.0 mL.
Density = mass/volume = 6 g/30.0 mL = 0.2 g/mL
