A piston in a gas supply pump has an area of $400\,\text{cm}^2$. This pump forces the gas against a constant pressure of $3000\,\text{Pa}$. For part of the stroke, the piston travels $25\,\text{cm}$ in one direction. What amount of work is carried out by the piston in this motion?
- A30 J
- B$3.0 \times 10^3\,\text{J}$
- C$3.0 \times 10^5\,\text{J}$
- D$3.0 \times 10^7\,\text{J}$
