I believe you mean 6.02*10^7 but you want to shift the decimal 7 times to the right which would be 60200000 (:

The correct answer would be B. The first level contains two and the second level contains six holding a total of eight, the reason eight aren't just in one row is because only two fit in the first row.
Answer:
Therefore,
The speed of the wave on the longer wire is 95 m/s.
Explanation:
Given:
For Short wire, speed is

Let length of Short and Longer wire be
such that

To Find:
Speed on the longer wire
Solution:
The speed of a pulse or wave on a string under tension can be found with the equation,

Where,
= Tension on the wire
L = Length of Sting
m = mass of String
So here we have,
= same

Therefore,
......equation ( 1 )
And
.......equation ( 2 )
Dividing equation 1 by equation 2 and on Solving we get

Therefore,

Therefore,
The speed of the wave on the longer wire is 95 m/s.
