Answer:
The relative density of the second liquid is 7.
Explanation:
From archimede's principle we know that the force that a liquid exerts on a object equals to the weight of the liquid that the object displaces.
Let us assume that the volume of the object is 'V'
Thus for the liquid in which the block is completely submerged
The buoyant force should be equal to weight of liquid
Mathematically
Thus for the liquid in which the block is 1/7 submerged
The buoyant force should be equal to weight of liquid
Mathematically
Comparing equation 'i' and 'ii' we see that
Since the first liquid is water thus 
Thus the relative density of the second liquid is 7.
Answer:
The principle of superposition which is also called superposition property,states that when two or more waves of the same type cross at some point, the resultant displacement at that point is equal to the sum of the displacements due to each individual wave.
Explanation:
<span>You can use one or more of your five senses to make observations during an inquiry activity.
we have nervous system which has special sensory system, we have sensory organs and senses, the five senses are touch, smell, hearing, sight and taste. every sense is related to an organ, like we can touch with hands, hear with ears, sight is related to eyes, we can smell with nose and taste with tongue.
