You have designed and constructed a solenoid to produce a magnetic field equal in magnitude to that of the earth (5.0 10-5 t). if your solenoid has 350 turns and is 31 cm long, determine the current you must use in order to obtain a magnetic field.

Jessie ran 5000 meters from the cops and an average speed of 6 meters / second before he got caught . how long did he run?

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?

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
