A long solenoid with radius r = 7 cm and n = 3,170 turns/m carries a current i = 6. 7 a. What is the magnitude of the magnetic f
kondaur [170]

The magnitude of the magnetic field in the central area inside the solenoid, in T is 0.0267 T

<h3>Magnetic field inside solenoid</h3>

The magnetic field inside the central area of the solenoid is given by B = μ₀ni where

  • μ₀ = permeability of free space = 4π × 10⁻⁷ Tm/A,
  • n = number of turns per unit length = 3,170 turns/m and
  • i = current in solenoid = 6.7 A

Since B = μ₀ni

Substituting the values of the variables into the equation, we have

B = μ₀ni

B = 4π × 10⁻⁷ Tm/A × 3,170 turns/m × 6.7 A

B = 4π × 10⁻⁷ Tm/A × 21239 A-turns/m

B = 84956π × 10⁻⁷ T

B = 266897.15 × 10⁻⁷ T

B = 0.026689715 T

B ≅ 0.0267 T

So, the magnitude of the magnetic field in the central area inside the solenoid, in T is 0.0267 T

R + (-5r)<br><br> Please explain how it's done.
Lisa [10]

Answer:

-4r

Step-by-step explanation:

r + (-5r)

1r + (-5r)

Factor out an r

r( 1 -5)

One minus 5 is negative 4.   If you have one dollar and you borrow five dollars,  how much did you borrow?  4  but that 4 is borrowed so it is negative


r (-4)

-4r

The boys had 5 4 6 gallons of water to share throughout the day. James drank 1 1 3 5 6 1 2 gallons and Simon drank 2 3 gallon. H
dsp73

Answer:

1\frac{1}{3}

Step-by-step explanation:

Total Volume of Water = 5\frac{4}{6}

Volume drunk by James =1\frac{1}{3}

Volume drunk by Simon =\frac{2}{3}

Volume drunk by Matthew = 1\frac{1}{2}

Volume drunk by Gilbert =\frac{5}{6}

Total Volume Drunk (i.e. The Sum) = 1\frac{1}{3} + \frac{2}{3} + 1\frac{1}{2} +\frac{5}{6}=\frac{13}{3}

Volume of water Left = Total Volume of Water-Total Volume Drunk

= 5\frac{4}{6}-\frac{13}{3} =\frac{4}{3}=1\frac{1}{3}
