Gases produced during the combustion of a fuel-air mixture, enter a nozzle at 200kpa, 150°c and 20m/s and leave the nozzle at 100kpa and 100°c. The exit area of the nozzle is 0.03m². Assume that these gases behave like an ideal gas with Cp = 1.15 kJ/kg. K and Y = 1:3, and that the flow of gases through nozzle is steady and adiabatic. Determine i. the exit velocity ii. the mass flow rate.

Copper has free electrons per cubic meter. a 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 a of current. (a) how much time does it take for an electron to travel the length of the wire? (b) repeat part (a) for 6-gauge copper wire (diameter 4.12 mm) of the same length that carries the same current. (c) generally speaking, how does changing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
