Awooden cylinder of length l and cross-sectional area a is partially submerged in a liquid with the axis of the cylinder oriented straight up and down. the density of the liquid is rhol. if the length of the cylinder that is below the surface of the liquid is d. a. what is the buoyant force that the liquid exerts on the cylinder? (ignore the small buoyant force exerted by the air on the part of the cylinder above the surface of the b. if the cylinder floats in the position described in the previous part, what is the density of the cylinder? (ignore the small buoyant force exerted by the air on the part of the cylinder above the surface of the liquid.)

J. j. thomson’s experiment disproved the theory that an atom

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
