Answer:

1.6\times 10^{-7} N

2.4\times 10^{-7} N

Explanation:

i_{1} = 1 A

i_{2} = 4 A

r = distance between the two wire = 5 m

F = Force per unit length acting between the two wires

Force per unit length acting between the two wires is given as

F = \frac{\mu _{o}}{4\pi }\frac{2i_{1}i_{2}}{r}

F = (10^{-7})\frac{2(1)(4)}{5}

F = 1.6\times 10^{-7} N

r'} = distance of each wire from the midpoint = 2.5 m

Magnetic field midway between the two wires is given as

B = \frac{\mu _{o}}{4\pi } \left \left ( \frac{2i_{2}}{r'} \right - \frac{2i_{1}}{r'} \right \right ))

B = (10^{-7}) \left \left ( \frac{2(4)}{2.5} \right - \frac{2(1)}{2.5} \right \right ))

B = 2.4\times 10^{-7}

If a raindrop is 0.05 cm3 in volume, what would the volume of an avogadro number of raindrops be?
zhenek [66]
If a raindrop is 0.05 cm^3 in volume, then <span> the volume of an Avogadro number of raindrops be 3.011 x 10^22 cm^3. To calculate this value, we simply multiply the volume given to Avogadro's number which </span><span>represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23.</span>
