Two horizontal curves on a bobsled run are banked at the same angle, but one has twice the radius of the other. the safe speed (for which no friction is needed to stay on the run) for the smaller radius curve is v. what is the safe speed on the larger radius curve?

Why do electron microscopes have higher resolving power than light microscopes?

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 accounts for an increase in the temperature of a gas that is kept a constant volume
