Question

The micrometer (1 μm) is often called the micron. (a) How many microns make up 2.4 km? (b) How many centimeters equal 2.4 μm? (c) How many microns are in 2.4 yd?

Answer 1

Answer:

(a) $2.4\times 10^9micron$

(B) $2.4\times 10^{-4}cm$

(C) $2.194\times 10^6micron$

Explanation:

We have given 1 micrometer is called 1 micrometer

So $1micron=10^{-6}m$

(A) We have given 2.4 km

We know that 1 km = 1000 m

So 2.4 km = 2400 m

As $1m=10^{6}micron$

So in 2400 m  $=2400\times 10^{6}=2.4\times 10^9micron$

(B) We have given 2.4 micrometer

We know that $1\mu m=10^{-6}m$

So $2.4\mu m=2.4\times 10^{-6}m$

As we know that 1 m = 100 cm

So $2.4\times 10^{-6}m=2.4\times 10^{-4}cm$

(C) We know that 1 yard = 0.9144 m

So 2.4 yard will be equal to $=0.9144\times 2.4=2.194m$

As $1m =10^{6}micron$

So 2.194 m $=2.194\times 10^{6}micron$
