Question

A 4um long Bacterial cell was magnified and drawn to a dimension of 6 cm. How many times has it been magnified 1)1.5x10to the power1 2)1.5x 10 to the power 4
3)15x 10 to the power 4 4)1.5

Answer 1

The bacterial cell is magnified = $1.5\times 10^4 times$

Explanation:

Here,Length of Bacterial cell = 4um

                                               = $4\times10^-^6m$

         Dimension to which it was drawn = 6cm

                                                                   =$6\times10^-^2m$      

Magnification of cell = $\frac{6\times10^-^2m}{4\times10^-^6m}$                                        

                                 = $1.5\times 10^4$

Hence,the bacterial cell is magnified = $1.5\times 10^4 times$
