There is a clever kitchen gadget for drying lettuce leaves after you wash them. it consists of a cylindrical container mounted so that it can be rotated about its axis by turning a hand crank. the outer wall of the cylinder is perforated with small holes. you put the wet leaves in the container and turn the crank to spin off the water. the radius of the container is 13.2 cm. when the cylinder is rotating at 1.70 revolutions per second, what is the magnitude of the centripetal acceleration at the outer wall?

According to the phase diagram for water, how is the state of water determined? proceed up a vertical line at any given temperature read the phase at the intersection of any given temperature and pressure at a given pressure, proceed horizontally to the s-l or l-g line

What color of light must blue light mix with to create white light? a. yellow b. white c. blue d. green

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.
