Hey there!

Let's think of this with a simpler example. Let's say one package is 4 pounds and one is 2 pounds. How many times heavier is the first than the second?Well, two, because the first package is double the weight of the second package! It's twice as heavy! And to get to that number, we divide four by two!

So, in our actual problem, we just divide 3.92 (bigger package) by 2.8 (smaller package).

3.92÷2.8=1.4

So, the first package is 1.4 times heavier than the first one!

Have a wonderful day!

In an optical fibre, the power drops by a factor of 10 approximately every 30 km. If the transmit power is 0. 35 W, how far will
IgorC [24]

Answer:

  • 30000 km

Step-by-step explanation:

First convert the transmit power into μW, considering 1 W = 1000000 μW:

  • 0.35 W = 0.35*1000000 μW = 350000 μW

Find how many factors of 10 the power dropped:

  • 350000 / 350 = 1000

Find the distance:

  • 1000*30 km = 30000 km
