Expert Solution

Answer to Problem 46E

The fire feels the same heat as before xn=2023ft

Explanation of Solution

Given:

  H varies inversely x3 or v is inversely proportional to x3

Concept used:

If the quantities x and y are related by an equation

  y=kx

For some constant k0

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

The constant k is called constant proportionality

Calculation:

If the quantities H,w and x3 are related by an equation

  Hαwx3

  H=kwx3

For some constant k0

That is H varies inversely x3 or v is inversely proportional to x3

The constant k is called constant proportionality

  x=20ftwn=2wHn=Hkwx3=kwxn3w203=2wxn3xn3=(2×203)xn=2023ft
