Two wires are made of the same material but the second wire has twice the diameter and twice the length of the first wire. When the two wires are stretched, and the tension in the second wire is also twice the tension in the first wire, the fundamental frequency of the first wire is 730 Hz. What is the fundamental frequency of the second wire? Answer in units of Hz.

Explanation:

For frequency in a wire , the expression is

n = , n is frequency , T is tension , m is mass of wire per unit length

 r is radius of the wire

For first the expression can be written as

730 =

For second wire

n =  length = 2l , tension = 2T , radius = 2r .

Dividing

n / 730 = 1 / 2 √2

= 1 / 2.828

n = 258.13 Hz

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
