Hey guys, i'm at 10 grade at school i have a physics question about stress tension and young modulus ? Please this is my questio
makvit [3.9K]
Use the eq. of Young modulus Y=(F/A)/(∆l/lo)
dimana ∆l is the elongation of wire, lo is its initial length.
So ∆l = (F/A)lo/Y.
∆l = (1000N/(6.5 × 10^-7 m^2))×(2.5m)/(2.0 × 10^-11 N/m^2)
Use calculator to finish it.

The unit of current, the ampere, is defined in terms of the force between currents. Two 1.0-meter-long sections of very long wir
Paha777 [63]

Answer:

1.6 x 10^{-7} N

Explanation:

If the force between two actual wires has this value, the current is defined to be exactly 1 A.

The force between two parallel wires carrying current can be defined as,

F=  μI_{1} I_{2} L/ 2πd

where,

current I_{1} = 1Amp

current I_{2} = 2amp

Length 'L'= 1m

distance 'd'= 2.5m

permeability of free space 'μ'= 4πx10^{-7} N/m

Putting the above values in the equation,

F=( 4πx10^{-7} x 1 x 2 x 1 )/ 2πx2.5

F= 1.6 x 10^{-7} N
