I NEED HELP NOW Which ball (frame A or B) is moving with a higher velocity when it strikes the ground, and which ball has the greatest kenetic energy?

A: the ball in frame A had the highest velocity, and the ball in frame B has the highest kinetic energy

B: the balls in frame A and B have the same velocity, while the ball in frame B had the highest kenetic energy

C: the ball in frame B has the highest velocity and the highest kenetic energy

D: the ball in frame A has the highest velocity and the highest kenetic energy

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
