Writw the following statements using symbols of variation 1).The weight(W) of a piece of iron varies directly as it's volume (V)
Answers
Given : Statement
The weight (W) of a piece of iron varies directly as its volume (V).
To Find : Write the statement using symbols
Solution:
The weight (W) of a piece of iron varies directly as its volume (V).
=> W ∝ V
W = Weight
V = Volume
∝ symbol of proportionality
W = dV
where d is constant of proportionality and is density here
The weight (W) of a piece of iron varies directly as its volume (V)
W ∝ V
Additional Info:
Direct variation if a variable increases then other variable also increases with a constant factor y = kx
inverse variation if a variable increases then other variable decreases with a constant factor xy = k
Joint variation is a relationship between atleast three variables, where one variable varies directly with all other variables.
y = kxz
Combined Variation is a relationship between three or more variables where it is in direct variation with few variable and in inverse variation with other variable y = kx/z
