A typical coal-fired power plant burns 350 metric tons of coal every hour to generate 2.6x106 MJ of electricity. 1 metric ton = 1000 kg; 1 metric ton of coal has a volume of 1.5 m³. The heat of combustion is 28 MJ/kg. Assume that all heat is transferred from the fuel to the boiler and that all the work done in spinning the turbine is transformed into electrical energy. Correct Correct answer is shown. Your answer 88.11 m was either rounded different different number of significant figures than required for this part. Part B What is the power plant's thermal efficiency? Express your answer as a percentage. VE ΑΣΦ e = ? %

If you expended 1500 watts for 3 hours, how many kilowatt-hours (kWh) would that be? Enter answer as number followed by a space and then the correct units (i.e "123 Unit").
In Arizona, photovoltaic (PV) panels can generate an average annual power of 1 MW/acre. If there are 311 sunny days per year in Arizona, but only 160 sunny days per year in Pennsylvania, how much average power (in MW/acre) could the same PV panels generate in Pennsylvania? Please include two decimal places in your answer. Note: assume that a cloudy day delivers 0 watts/acre of solar power. This is not true, but it simplifies the problem for us.
Many decisions are made on the basis of the payback period: the time it will take through savings to equal the capital cost of an investment. Acceptable payback times depend upon the business or philosophy one has. (For some industries, a payback period is as small as two years.) Suppose you wish to install the extra insulation. If energy cost $1.00 per million joules and the insulation was $4.00 per square meter, then calculate the simple payback time. Take the average for the 120 day heating season to be 15.0C.
A 400 kg satellite is in a circular orbit at an altitude of 425 km above the Earth's surface. Because of air friction, the satellite eventually falls to the Earth's surface, where it hits the ground with a speed of 1.80 km/s. How much energy was transformed into internal energy by means of air friction? Need Help? Read It
Hello, I have a physics assignment and wanted to get help with the answers. I was told to repost the question to get the remaining sub parts done. I accidentally posted a photo a few minutes ago without the instructions I just need the bottom four completed.
bacon-cheddar-double-burger meal along with A 65.0-kg mountain climber just ate a Johnny Rocket's two peanut butter milkshakes, which have 5810 Calories (5810 kilocalories). Assume she can convert these calories into energy with 100% efficiency and use the fact that 1 kcal = 4186 J. Calculate how many times she could climb up Mt. Everest - the world's tallest mountain. The height of Mt. Everest is 8840 m.
