Identify the incorrect statement about a single motor unit.- fine motor skills depend on the development of small motor units.- the smaller the number of muscle fibers, the more precise the movement.- muscle fibers of one motor unit intermingle with the fibers of another motor unit.- some motor units include as many as 2000 muscle fibers.- the more neurons involved, the more powerful the contraction.

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

Acoal-fired plant generates 600 mw of electric power. the plant uses 4.8 x 10^6 kg of coal each day, and the heat of combustion of coal is 3.3x 10^7 j/kg. the steam that drives the turbines is at a temperature of 300° c, and the exhaust water is at 37° c. (a) what is the overall efficiency of the plant for generating electric power? (b) how much thermal energy is exhausted each day? (c) what is the change in entropy of the universe for this heat engine? (d) using the same heat reservoirs, what is the maximum possible (carnot) efficiency for a heat engine?

Which is the most accurate name for the ionic compound cas?
