What is the constant of proportionality for m=32•g

lina2011 [118]

Answer:

∴ Constant of Proportionality is 32

Step-by-step explanation:

Here Given;

$m=32\times g$ (equation-1)

$\frac{m}{g}=32$ (equation-2) (divide with 'g' on both side)

We know,

The Constant of Proportionality equation is given;

$y=k\times x$ (equation-3)

Where 'k' is known as Constant of Proportionality.

Comparing equation-1 and equation-3;

$y=m$ and $x=g$

Now equation-2 become;

$k=\frac{y}{x}$

Plug $y=m$ and $x=g$ in above equation;

$\frac{m}{g}=k$ (equation-4)

By comparing equation-2 and equation-4;

$k=32$

So Constant of Proportionality is 32
