A power station that burns coal as its fuel has a mean power output of $3000\,\text{MW}$. Every day, coal is delivered by $20$ trains. The station’s efficiency in changing the thermal energy given out by the coal into electrical energy is $26\%$. When $1.0\,\text{kg}$ of coal is burned, it releases $33\,\text{MJ}$ of thermal energy. What mass of coal is carried by each train?
- A$2.5 \times 10^4\,\text{kg}$
- B$6.3 \times 10^4\,\text{kg}$
- C$1.5 \times 10^6\,\text{kg}$
- D$3.0 \times 10^7\,\text{kg}$
