Answer:

The correct solution is "5\times 10^{-4} %".

Explanation:

The given values are:

Pressure,

\Delta P=7\times 10^5 \ N/m

for copper,

B=14\times 10^{10} \ N/m

As we know,

The Bulk Modulus (B) = \frac{\Delta P}{-\frac{\Delta V}{V} }

or,

The decrease in volume will be:

= (\frac{\Delta V}{V})\times 100 \ percent

then,

= \frac{\Delta P}{B}\times 100 \ percent

On putting the values, we get

= \frac{7\times 10^5}{14\times 10^{10}}\times 100 \ percent

= 5\times 10^{-4} \ percent

a transmission-line cable, of length 3 km, consists of 19 strands of identical copper conductors, each 1.5 mm in diameter. becau
Ivan

the resistance of the cable is 582.9 ohms

we are given the length of the cable which is  3 km,  of  1.5 mm in, the diameter  and resistivity of copper which is 1.72 m

The formula  we are referring to for calculating the resistance of the  cable is

R = ρl/A.

As there are 19 strands of copper conductors, so the resistance will be

R = 19( ρl/A)

Here  ρ is the resisitivity =  1.72 , l is the length  = 3(1+0.05)*10³3= 3150 m

A=pie/4(1.5 x 10⁻³)^2 =1.766 x 10⁻⁶ =1.766 x 10^-6

Substituting the values in the formula  we  get

R = 19 ( 1.72*3150 )/1.766 x 10⁻⁶

 = 582.9 ohm
