The weight of air measured in units of force per area is called
a. air viscosity
b. air pressure
c. air resistance
d. relative pressure

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)

The amount of work done is determined by 2 factors. describe an example of work (using the scientific definition) list the 2 factors that determine the amount of work done.
