Answer:
The possible frequencies for the A string of the other violinist is 457 Hz and 467 Hz.
(3) and (4) is correct option.
Explanation:
Given that,
Beat frequency f = 5.0 Hz
Frequency f'= 462 Hz
We need to calculate the possible frequencies for the A string of the other violinist
Using formula of frequency
 ...(I)
...(I)
 ...(II)
...(II)
Where, f= beat frequency
f₁ = frequency
Put the value in both equations


Hence, The possible frequencies for the A string of the other violinist is 467 Hz and 457 Hz.

Answer:
a) yield strength
    
b) modulus of elasticity
strain calculation
 
strain for offset yield point
 
                               =0.0046-0.002 = 0.0026
now, modulus of elasticity 
   
 
     = 184615.28 MPa = 184.615 GPa
c) tensile strength
  
d) percentage elongation
 
e) percentage of area reduction
  
                             
 
        
             
        
        
        
The statement which is true of a wave that’s propagating along the pavement and girders of a suspension bridge is A. The wave is mechanical, with particles vibrating in a direction that is parallel to that of the wave, forming compressions and rarefactions.
