The time taken by light to reach pluto will be 5.6 hours.
<h3><u>Explanation</u>:</h3>
The light is a electromagnetic wave that has the highest velocity and same velocity as all other electromagnetic radiations existing in this universe. The light takes about 8.2 seconds to reach from sun to earth. So lets check howmuch time does light take to reach pluto from sun.
The speed of light was calculated to be 
m/s. This is the speed of each and every electromagnetic waves.
The distance of pluto from sun is huge. On an average it's 
km or 
m.
So time taken by light to reach from sun to pluto will be 
seconds. Or actually 5.6 hours.
earthquakes produce both body and surface waves which is the fast sesmic wave!!
hope this helps!!
Answer:
The problem will be because:
- <u>The error in the construction of the bridge will be actually 40 cm</u>.
Explanation:
When you, as an engineer, listen about a scale 1/20, it means that for each 1 cm in the model, it will be 20 cm in the real footbridge (20 times upper to the scale model), then how the error in the model is 2 cm, the real error is 40 cm, in this case, imagine that you didn't know that the bridge will have an error of 40 cm, which is approximately 1,31 ft, <em><u>from a side of the bridge you begin with the correct measure, and the other side you use the measure with the error of the 40 cm, the result is that when you going to finish the bridge in the center, this won't match, making more expenses to correct that big error</u></em>.
