Gas always expands or contracts to exactly fill whatever you put it in.
So to measure the volume of a gas, just measure the volume of the jar, the tank, the bottle, the can, or the balloon that the gas is in.
Answer:
centripetal acceleration
Explanation:
convert 1.63rev/sec to rpm by multiplying by 60
= 1.63*60=97.8rpm
Convert this to rad/sec
1rpm =π/30 rad/sec
97.8rpm = 97.8 * (π/30 rad/sec)
=10.25rad/sec
linear velocity= angular velocity *radius
radius =13.2cm=13.2/100=0.132m
v=rω
v= 0.132*10.25
v=1.35m/s
centripetal acceleration =
Distance and displacement are hardly ever equal.
Remember that 'displacement' is the straight-line distance between
the start-point and the end-point, regardless of what path you followed
on the way.
So they're equal ONLY when the trip from start to finish was completely
in a straight line.
Before a star is born, the matter that will become the star exists as a interstelar gas and dust. The stars are formed as a result of the forces:the force of gravity compresses atoms in the interstellar gas. Then the fusion reaction begins. During this fusion reaction the temperature gets extremely high and all the material evolves into a hot bright star.
