6. Water, in a closed system, enters the 90° elbow at ଵ= 7 fps and pressure pଵ= 12 psi. Find the x- and ycomponents of the force on the elbow. 13 in 9 in ଵ ଶ pଵ pଶ Force (x-direction) = Force (y-direction) =

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

There are two-speed cameras, one in an are where the speed limit is 30 km/h and another where the speed limit is 50 km/h. in which will there be a smaller time interval between the photographs? explain your answer.
