Assuming 27000 MWh of electricity consumption from the VT power plant and 35% efficiency for this power plant, but only 3% transmission loss since the transmission distances are much shorter, calculate the amount of coal (tons) required for the VT on-campus electricity generation assuming a fuel mix of 30% coal/70% natural gas based on energy

How does convection affect our atmosphere? our layers of earth? our oceans?

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

Argon, neon, and xenon are examples of
