He diagram shows a person holding a bow and arrow. A person holds a bow and arrow with the arrow pulled back.
Which will most likely increase the kinetic energy in this system?

pulling farther back on the string
releasing the string
holding the arrow higher
decreasing the mass of the arrow

A( developed during the process of technology design

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.

Atemperature inversion can cause a warm air mass to move over a colder air mass. this traps the colder air mass and prevents surface air from rising. this may result in which of these? a) smog b) acid rain c) freezing rain d) a thunderstorm
