Answer:
Explanation:For example, you are in a bus and it goes with the velocity of 50 m/s to the east, then a truck passes you with a velocity of 60m/s to the east. ... Velocity of the moving objects with respect to other moving or stationary object is called “relative velocity” and this motion is called “relative motion”
Answer:
The object will float on the surface of water if its density is less than the equal volume of water.
Explanation:
Density:
It is define as mass per unit volume.
d=m/v
it is mostly measure in g/mL
it is represented by ρ (rho)
The density of water is one gram per cubic centimeter. If the object is less denser than water it will float. If the density of object is greater than the density of water it will sink.
Other examples:
some rocks are more denser then water so they will sink in it.
density of oil is less than vinegar, so it will float on the surface of vinegar
