Will two sounds of 50 db constitute a sound of 100 db . Explain

1 answer:

6 0

Two sounds of 50 db each will NOT constitute a 100 db sound. This is because, the relation that relates levels of sounds is a logarithmic relation and not a direct relation of addition. <span>Each 10 dB increase in sound makes the sound 10 times louder.
</span>This means that, for 50 db, the resultant sound level will be <span>twice as loud is an increase of 10Log (2) = 3.01dB
</span>
The final sound level = 50 + 3.01 = 53.01 db

Find the perimeter of the rectangle if each block represents one foot(show your calculation)

iren2701 [21]

I'm pretty sure that the "block" of which you speak is one in a pattern
of them that covers the drawing you have of the rectangle, and now
I need to explain something to you:

The REASON for printing that drawing next to the question that you
partially copied is that the drawing has information that's needed to
answer the question with, and rather than repeat all that information
in the question, it just says "LOOK AT THE DRAWING !"

In fact, the whole point of the question may not be just to remind you of
what "perimeter" means. It's more likely that the purpose of this problem
is to make you pick the information you need off of a drawing.

Either way, if you'll kind of "read between the lines" of the part of the
question that you DID copy, it should be pretty obvious to you that nobody's
going nowhere in the direction of a solution without SEEing the drawing.

So my bottom-line conclusion regarding a solution for this problem is:
Not possible with the given information.

If the Sun suddenly turned off, we would not know it until its light stopped coming. How long would that be, given that the Sun

Yuliya22 [10]

Answer:

8.33 minutes

Explanation:

First let us find out how much time it takes for the light for the sun to reach the earth

Distance between Earth and Sun is 1.5×10¹¹ m

Speed of light = 3×10⁸ m/s

$\text{Time taken}=\frac{1.5\times 10^{11}}{3\times 10^8}\\\Rightarrow \text{Time taken}=500\ seconds$
