A wire is stretched between two posts. Another wire is stretched between two posts that are four times as far apart. The tension
Elena-2011 [213]

Answer:

Therefore,

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

Explanation:

Given:

For Short wire, speed is

v_{s}=190\ m/s

Let length of Short  and Longer wire be L_{s}\ and\ L_{l} such that

L_{l}=4\times L_{s}

To Find:

v_{l}=?  Speed on the longer wire

Solution:

The speed of a pulse or wave on a string under tension can be found with the equation,

v=\sqrt{\dfrac{F_{T}\times L}{m}

Where,

F_{T} = Tension on the wire

L = Length of Sting

m = mass of String

So here we have,

F_{T} = same

L_{l}=4\times L_{s}

Therefore,

v_{s}=\sqrt{\dfrac{F_{T}\times L_{s}}{m} ......equation ( 1 )

And

v_{l}=\sqrt{\dfrac{F_{T}\times L_{l}}{m}  .......equation ( 2 )

Dividing equation 1 by equation 2 and on Solving we get

\dfrac{v_{s}}{v_{l}}=\sqrt{\dfrac{L_{s}}{L_{l}}}

Therefore,

v_{l}=v_{s}\sqrt{\dfrac{4\times L_{s}}{L_{s}}}=190\times 2=380\ m/s

Therefore,

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

Explain what happens to the total mass of a mixture when it is separated?
SIZIF [17.4K]
The total mass of the mixture would not change.

Think about it as a mix of marbles. Suppose you have a group of 10 marbles. 5 marbles are red, and 5 marbles are blue. If you separate the marbles into 2 different groups by color, you still have 10 marbles in total, but they are separated and no longer a mixture of colors.
