The volume of the water in the graduated cylinder rose
as some of the water was displaced by the table tennis
ball. Find the volume of the ball using the formula
V = Vf-V;
where Vi is the volume of the ball, Vi is the final volume
of the water, and V; is the initial volume of the water.
Record the volume of the ball in Table A of your Student
Guide.

The energy of a photon was found to be 3.38 × 10–19 j. planck’s constant is 6.63 × 10–34 j • s. which color of light corresponds to this photon?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

Consider a system with two masses that are moving away from each other. why will the kinetic energy differ if the frame of reference is a stationary observer or one of the masses?
