As one goes far away from the Earth, the density of air
B. becomes less
C. remains constant
D. increases twice.
A ferry boat floats in seawater because its density is
When a body floats in a liquid:
A. its weight is less than the upthrust on it
B. its weight is greater than the upthrust on it
C. its weight is equal to the upthrust on it
D. its volume is equal to the volume of liquid displaced.
When a body floats in water:
A. It displaces its own volume of water.
B. The mass of the water displaced by the body is equal to its own mass
C. It weighs the same as in air
D. The downthrust is more than the upthrust.
