#### Solutions

Chapter 1.11, Problem 11E
To determine

## To find:The equation given that the statement

Expert Solution

The equation is z=ky

### Explanation of Solution

Given:

T is directly proportional to the square root y

Concept used:

If the quantities x and y are related by an equation

y=kx

For some constant k0

That is y varies directly as x or y is directly proportional to x

The constant k is called constant proportionality

Calculation:

If the quantities z and y are related by an equation

zαy

z=ky

For some constant k0

That is z varies directly as y or T is directly proportional to y

The constant k is called constant proportionality
