Compare the image formed by a concave and convex mirror.

an aqueous solution started at pH=4.50, but with the addition of an acid reduced to 3.70. at the end the total V = 125.77mL. Solid SrCO3 was added (MM=147.63 g/mol) to reestablish the original pH. what mass of base is required. enter you answer in scientific notation

Draw your own theoretical potential energy diagram that have the

following (5 points):

• Total mechanical energy

• Maximum displacement / position (at least one)

• Turning point (at least one)

• Equilibrium points (at least two)

Be sure to label the x and y axes of your graph. The line of the graph can

assume any shape, as long as the rules for drawing the potential energy

diagram are followed.

A basketball is shot through the air, hitting the backboard of a hoop. During the shot, the basketball was travelling at 8 m/s, and right after hitting the backboard, the basketball travels 1 m/s in the opposite direction. The mass of a standard basketball is 590g.

a. Find the kinetic energy of the basketball before hitting the backboard (2pts)

b. Find the kinetic energy of the basketball after hitting the backboard (2pts)
