Two long parallel wires carry currents of 3.35 A and 6.99 A . The magnitude of the force per unit length acting on each wire is 6.03 × 10 − 5 N / m . Find the separation distance d of the wires expressed in millimeters.

d = 77.5mm

Explanation:

The expression used for calculating the force between two parallel wires carrying currents separated by a distance is;

F12 =µµol1I2L/2πd where

I1 and I2 are the currents in both wires

L is the length of the wires

d is the separation distance

F12 is the magnitude of the force between them.

µo is the constant of proportionality

The equation can be rewritten as;

F12/L = µµol1I2/2πd

F12/L is the force per unit length acting on each wire= 6.03×10^-5 N/m

I1 = 3.35A

I2 = 6.99A

µ = 1

µo = 4π×10^-7N/A²

d =?

Substituting this datas in the equation above to get the separation distance d we have;

6.03×10^-5 =1× 4π×10^-7 × 3.35 × 6.99/2πd

6.03×10^-5 = 4×10^-7×23.42/2d

6.03×10^-5 = 9.37×10^-6/2d

2d = 9.37×10^-6/6.03×10^-5

2d = 1.55 × 10^-1

d = (1.55 × 10^-1)/2

d =0.155/2

d = 0.0775m

Since 1m = 1000mm

0.0775m = (0.0775×1000)mm

d = 77.5mm

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
