Answer:
Options (A), (B), (D), and (E).
Explanation:
Density is a physical property that describes the relationship between mass and volume. This property shows whether an object will float or it will get sink. The density of substances changes with the changing temperature, as both are inversely proportional to each other.
Mathematically, density can be written as,
Density = 
ρ = 
, Where, ρ = density, m = mass, v = volume
Thus, the correct answers are options (A), (B), (D), and (E).
Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it ha

Answer:
Horizontal distance is 1.28 + 2.04 = 3.32 m
Explanation:
Given data:
from below figure
Applying Pythagoras theorem
from Snell's law
solving for x we have
x = 1.28
Horizontal distance is 1.28 + 2.04 = 3.32 m
