Dear Student,
(A) Density = Mass/Volume = 500 gm / 350 cm3 = 1.43 gm/cm3
(B) The solid will displace a volume of water equal to it's own volume since the density of this solid is greater than the density of water.
Mass of water = Density of water x Volume of water = 1 gm/cm3 x 350 cm3 = 350 gm
(C) Relative density = Density of solid/Density of water = 1.43/1 = 1.43
(D) It'll sink in water, since density of solid is more than the density of water.

A boy throws a steel ball straight up. Consider the motion of the ball only after it has left the boy's hand but before it touches the ground and assume that forces exerted by the air are negligible. For these conditions, the force(s) acting on the ball is (are): a. A downward force of gravity along with a steadily decreasing upward force b. A steadily decreasing upward force from the moment it leaves the boy's hand until it reaches its highest point on the way down there is a steadily increasing downward force of gravity as the object gets closer to the earth c. Constant downward force of gravity along with an upward force that steadily decreases until the ball reaches it highest point on the way down there is only a constant downward force of gravity d. Constant downward force of gravity only
