Question

Find an integer which when multiplied by 2 and divide by 3 becomes (-12)

Answer 1

Step-by-step explanation:

Given: r1 : r2 = 4 : 3

To find: W1 : W2

Formulae: W = 2TdA [½]

Calculation: From formula,

Work done to blow both bubbles,

`W_1-2T(4pir_1^2); and W_2=2T(4pir_2^2)`

`W_1/W_2=(r_1/r_2)^2`

`=(4/3)^2`

=16 : 9

The ratio of work done to blow the bubbles is 16 : 9.
