Find the work done by gas?
salantis [7]

The work done by the gas when the gas expands will be 567.65 ft-lb.

<h3>What is the work done for an isothermal process?</h3>

The Pressure is inversely proportional to the volume.

Let the initial pressure and initial volume be P₁ and V₁, and the final volume be V₂.

Then the work done by the gas will be

WD = P₁ V₁ ln (V₂ / V₁)

A quantity of the gas with an initial volume of 2 cubic feet and an initial pressure of 700 pounds per square foot.

The gas expands to a volume of 3 cubic feet.

Then the work done by the gas will be

WD = 700 x 2 x ln (3/2)

WD = 1400 x 0.405

WD = 567.65 ft-lb

The work done by the gas when the gas expands will be 567.65 ft-lb.

More about the work done for isothermal process link is given below.

Try this please, it's about arcs and angles and I'm just not sure how to do it. Thanks!
Nataly_w [17]
Check the picture below.

the segment LOJ is a diameter, and therefore the arcLCJ made by that diameter will have a central angle of 180°.

that simply means that the arcLC is 180 - 94, or 86°.

the ∡LJC is an inscribed angle that is intercepting the arcLC, and therefore, by the inscribed angle theorem, it'll be half of arcLC.
