at the bottom of a liquid depends only on the vertical….. of the liquid.
a) height
b) depth
c) area
d) volume
Explanation:
According to Archimedes’s
principle the buoyant force acting on an
object fully or partially submerged in a fluid is equal to the weight of the
fluid displaced by the object.
For every object whether it floats or sink depends on the
object’s……….relative to the fluid.
a) volume
b) area
c) pressure
d) density
