An Otto cycle has the lowest temperature at 290 K and the lowest pressure at 85 kPa. The highest temperature is 2400 K and combustion adds 1200 kJ/kg as heat transfer. This cycle is used in a 2.4 L engine, running at 1800 RPM. How much power does it produce?
What power is dissipated in a single light. A proton is fixed in place. An electron is released from rest and allowed to collide with the proton. Then the roles of the proton and electron are interchanged, and same experiment is repeated. Which is ..
An electron beam in an oscilloscope is deflected by the electric field produced by oppositely charged metal plates. If the electric field between the plates is 2.75 105 N/C directed downward, what is the magnitude and direction of the force on eac..
The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656 nm (red) and 486 nm (blue). Light from a hydrogen lamp illuminates a diffraction grating with 460 lines/mm , and the light is observed on a screen 1.7 m b..
