10. During the Winter Olympic games at Lillehammer, Norway, in 1994, Dan Jansen of the United States skated 5.00 x 10²m in 35.76 s. Suppose it takes
Jansen 4.00 s to increase his velocity from zero to his maximum velocity,
which is 10.0 percent greater than his average velocity during the whole run.
Calculate Jansen's average acceleration during the first 4.00 s.

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?

Which transition by an electron will release the greatest amount of energy? oa ob oc od
