Question

W varies directly with u and inversely with d, in your equation use k as the correct constant of proportionality

Answer 1

Answer:

$W=\frac{u}{d}$

Explanation:

The definition of directly and indirectly proportional is mentioned below.

Directly proportional:

• On increasing of a quantity if the other quantity increases with the same rate then they are directly proportional to each other. The sign for directly proportional is ∝.
• If x is directly proportional to y then x ∝ y

Indirectly proportional:

• On increasing of a quantity if the other quantity decreases with the same rate then they are directly proportional to each other.

• If x is indirectly proportional to y then x ∝ 1/y

Further Explanation:

It has been given that W varies directly with u and inversely with d. So, from the above mentioned definitions, we have

$W\propto\frac{u}{d}$

Removing the proportionality sign and add a constant k

$W=\frac{u}{d}$

Therefore, the required equation is

$W=\frac{u}{d}$

Answer 2

The equation is given as W varies directly with u and inversely with d, then the equation is written as:
W = k1u
here k2 is the proportionality constant.
and p = k2$\frac{1}{d}$here k2 is the proportionality constant.
Thus, combining both equations we get, p = K$\frac{u}{d}$where K = K1*K2, is the proportionality constant.
