Abowling ball encounters a vertical rise of h = 0.612 m on the way back to the ball rack. if the translational speed of the ball is 3.81 m/s at the bottom, what is its translational speed at the top?

How does the image distance (di) of a convex lens compare with the image distance of a concave lens? a. the image distance of the convex lens is positive, and that of the concave lens is negative. b. both are negative for a virtual image. c. both are positive for a virtual image d. the image distance of the convex lens is negative, and that of the concave lens is positive.

Which notation is used to represent an alpha particle? a. b. c. d.

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.)
