A copper wire 1.0 meter long and with a mass of .0014 kilograms per meter vibrates in two segments when under a tension of 27 Ne
Furkat [3]

Answer:

the frequency of this mode of vibration is 138.87 Hz

Explanation:

Given;

length of the copper wire, L = 1 m

mass per unit length of the copper wire, μ = 0.0014 kg/m

tension on the wire, T = 27 N

number of segments, n = 2

The frequency of this mode of vibration is calculated as;

F_n = \frac{n}{2L} \sqrt{\frac{T}{\mu} } \\\\F_2 = \frac{2}{2\times 1} \sqrt{\frac{27}{0.0014} }\\\\F_2 = 138.87 \ Hz

Therefore, the frequency of this mode of vibration is 138.87 Hz

Solar winds have an influence all the way to about 160 AU from the Sun. About how many kilometers is that?
Mumz [18]

Answer: A. 24,000,000,000 km

Explanation: An Astronomical Unit  commonly abbreviated as AU is the average distance between Earth and the Sun and is about 150 million kilometers.

Astronomical unit is mainly used to measure distances within our solar system.

1 AU is equal to  150\times 10^6 km

Thus 160 AU  is equal to \frac{150\times 10^6}{1}\times 160=24000\times 10^6km=24000000000km
