A bullet is fired straight upward from a certain height h with an initial velocity of 40m/s. If ittakes 10sec to reach the ground what is the height h?

Which accounts for an increase in the temperature of a gas that is kept a constant volume

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.

What is part of a line has one endpoint and continues in one direction?
