C. Differentiate between the following.
1. Density and relative density of a material
2. Floating and sinking
Answers
Floating means to stay in the surface of water without drowning.
Sinking means to fall below the surface of water (drowning).
Answer:
Floating and sinking :-
An object floats when the weight force on the object is balanced by the upward push of the water on the object. ... If the weight force down is larger than the upward push of the water on the object then the object will sink. If the reverse is true then the object will rise – rising is the opposite of sinking.
Explanation:
Density and relative density of a material :-
Density is by definition the ratio of the mass and volume of a body. ... Relative density is the ratio between the density of a measuring substance and the density of some other reference substance at a given temperature (typically water).
