9. Calculate the horizontal force that must be applied to a 1-kg puck to make it accelerate on a horizontal
friction-free air table with the same acceleration it
would have if it were dropped and fell freely?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)

Abowling ball rolling down the lane toward the pins has gravitational potential energy. a. no b. a lot of c. a little
