Determine (a) the net power developed in kW (b) the back work ratio, and (c) the thermal efficiency of the cycle . You may assume air to behave like an ideal gas.
A material that you are working with has a band gap of 4 eV but it is opaque (doesn't transmit light) because it contains many pores. Explain the mechanism for low light transmission in this material.
A typical car under hard braking loses speed at a rate of about 6 m/s2. The typical reaction time to engage the brakes is 0.50 s. A local school board sets the speed limit in a school zone such that all cars should be able to stop in 5.0 m. What m
