The final volume of the gas is 144.25 L
Explanation:
For an ideal gas kept at constant pressure, the work done by the gas on the surroundings is given by
where
p is the pressure of the gas
is the initial volume
is the final volume
For the gas in the cylinder in this problem,
p = 2.00 atm
And we also know the work done,
W = 288 J
So we can solve the equation for , the final volume:

Answer:
I will explain the concept of magnetic field and how it can be calculated.
Explanation:
The formula for magnetic field at the center of a loop is given as
B = μI / 2R
where B is the magnetic field
R is the radius of the loop
I is the current
and μ is the magnetic permeability of free space which is a constant 4π ×
newtons/ampere²
If the magnetic field at the center of the loop is 0, then μI = 0
I = 0 which means there will be no current flow in the loop.
