A string has a linear density of 8.5 x 10-3 kg/m and is under a tension of 280 N. The string is 1.8 m long, is fixed at both ends, and is vibrating in the standing wave pattern shown in the drawing. Determine the a. speed.
b. wavelength
c. frequency of the traveling waves that make up the standing wave.

a)  

b)  

c)  

Explanation:

From the question we are told that:

Linear density

Tension

Length of string

a)

Generally the equation for Speed of travelling wave is mathematically given by

b)

From the Drawing

Wavelength is given as

c)

Generally the equation for Frequency of travelling wave is mathematically given by

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
