To solve the problem, we can use Charle's law, which states that for an ideal gas at constant pressure the ratio between absolute temperature T and volume V remains constant:

For a gas transformation, this law can be rewritten as

(1)
where 1 and 2 label the initial and final conditions of the gas.
Before applying the law, we must convert the temperatures in Kelvin:


The initial volume of the gas is

, so if we re-arrange (1) we find the new volume of the gas:
Answer:
The second one
Explanation:
It caused both to change speed because they have both the same mass.
Answer:
C) 1200 rpm
Explanation:
= Diameter of bigger pulley = 24 inch
= Diameter of smaller pulley = 8 inch
= Speed of bigger pulley = 400 rpm
= Speed of smaller pulley
The relation between revolutions per minute and diameter is that they are inversely proportional.

The number of revolutions per minute of the smaller pulley is 1200 rpm
the answer on edginuity is B- Fluids (i just took the test)
Answer:
2.24kJ
Explanation:
Kinetic energy is the energy that a object possesses due to its motion.
Let kinetic Energy (KE),
Here both the Bicycle and the girl is travelling at the given speed , therefore we have to consider the total mass
according ti the definition ,
