The gas is in a rigid container: this means that its volume remains constant. Therefore, we can use Gay-Lussac law, which states that for a gas at constant volume, the pressure is directly proportional to the temperature. The law can be written as follows:

Where P1=5 atm is the initial pressure, T1=254.5 K is the initial temperature, P2 is the new pressure and T2=101.8 K is the new temperature. Re-arranging the equation and using the data of the problem, we can find P2:

So, the new pressure is 2 atm.
I think its A I hope this help thank you!!
Answer: Just a few examples are the tension in the rope on a tether ball, the force of Earth's gravity on the Moon, friction between roller skates and a rink floor, a banked roadway's force on a car, and forces on the tube of a spinning centrifuge. Any net force causing uniform circular motion is called a centripetal force.
Answer:
The speed is 
Explanation:
From the question we are told that
The length of the wire is 
The mass density is 
The tension is 
Generally the speed of the transverse cable is mathematically represented as

substituting values


Answer:
W = 7.5 J
Explanation:
W = KE
W = ½mv² = ½0.6(5²) = 7.5 J
