In anticipation of a long 7° upgrade, a bus driver accelerates at a constant rate of 3.8 ft/s2 while still on a level section of the highway. Knowing that the speed of the bus is 62 mi/h as it begins to climb the grade and that the driver does not change the setting of his throttle or shift gears, determine the distance traveled by the bus up the grade when its speed has decreased to 50 mi/h. (Round the final answer to three decimal places.) The distance travelled by the bus up the grade is

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

The process in which the system pressure remain constant is called a)-isobaric b)-isochoric c)-isolated d)-isothermal

The quality is zero at a)-the saturated vapour state b)-the saturated liquid state c)-the saturated liquid-vapour mixture state d)-none of the states in the other answers
