1/ Two strings made of the same material are subjected to the same tension (therefore the speed of sound will be the same in the two strings) but have different lengths. The first rope, A, is 80 cm long and the second, B, is 60 cm long. They are vibrated at various frequencies to produce standing waves.

Consider the first six partials of the two strings and determine which of the partials of string A will have the same frequency as one of the partials of string B.

Expert Solution

Here,
Length of string A
Length of string B
Speed of sound by string A
Speed of sound by string B

The fundamental frequency in string A:

Six partial frequencies of string A:

The fundamental frequency in string B:

Six partial frequencies of string B:

From the above calculation, we can see that only one partial has the same frequency from both strings. Frequency of string A and frequency of string B are the same.

Consider two wires made of the same material: 1) If both wires have the same radius, but wire 1 is half the length of wire 2, what is the resistance of wire 1 in terms of wire 2? 2) If both wires have the same length, but wire 1 has three times the radius of wire 2, what is the resistance of wire 1 in terms of wire 2?

13.18 Two piano strings with the same mass and the same length are to be tuned to 440 Hz (A on the equal temperament scale). One string, with a tension of 300 N is already tuned to 440 Hz. The second string frequency is 435 Hz. a) Should the tension of string 2 be increased or decreased to tune the frequency to 440 Hz? b) How much must the tension of string 2 be changed to change the frequency from...

Two metals of equal mass with different heat capacities are subjected to the same amount of heat. Which undergoes the smaller change in temperature (You must explain/justify your answer)? a) The metal with the higher heat capacity undergoes the smaller change in temperature. b) The metal with the lower heat capacity undergoes the smaller change in temperature. c) Both undergo the same change in temperature. d) You need to know the initial temperatures of the metals. e) You need to...

. A rectangular steel bar is subjected to a fluctuating load from 30 kN tension to 30 kN compression. The bar is 30 mm wide and 7 mm thick with a hole in the middle that is 4 mm in diameter. Find the fatigue and yield factor of safety if the steel is cold-drawn AISI 1040. If the fatigue factor nf<1 and ny>1 then that means that the system will fail at a finite number of cycles. If that is...

10. Two conducting loops of the same diameter, #1 made of copper and #2 made of aluminum wires of the same length and cross-sections are placed on the horizontal surface in a uniform magnetic field directed vertically up. The magnetic field vanishes suddenly. A) While the magnetic field is decreasing, the direction of induced emf force as viewed from above in these loops is: a. Clockwise b. Counterclockwise c. Different for copper and aluminum d. Zero B) The magnitude of emf in loop #1 is...

An isotropic sample of a material is subjected to a compressive stress of 230 MPa in the x direction. However, it is confined so that the sample cannot deform in the y and z directions. Data: Young’s modulus of the block E = 46 GPa Poisson ratio υ = ⅓ Height = 0.5 m Width = 0.5 m Length = 0.5 m Calculate these stresses in the y- and z-directions (in MPa to 2 decimal places) Calculate the strain in...

Take two identical closed strings, both tracing out exactly the same path in space. These two strings are coincident everywhere. Call this state I. Take a single closed string following exactly the same closed path as in the first case, but not closing just yet. The string goes around exactly the same path once again before closing in on itself. Two cycles around the same closed path. Call this state II. String field theory tells us unambiguously states I and...

1. Implement the function calculate_score that consumes three parameters, two strings and a list. The strings will each be ONE character and will represent a nucleotide. The list will be a nested int list representing a 4x4 score matrix. This function will return the value (int) from the nested int list at the location of the two referenced nucleotides. a. An example call to calculate_score would be calculate_score(“A”, “T”, score_matrix). If we look at the alignment score table in the...
