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.

Which statement about covalent bonds is true

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
