Which of the following is a true statement about magnetic fields

Physics
1 answer:
zaharov [31]3 years ago
8 0

a. the larger the current, the larger the magnetic field

Explanation:

The magnetic field produced by a current-carrying wire is given by the equation:

B=\frac{\mu_0 I}{2\pi r}

where

\mu_0 is the vacuum permeability

I is the current in the wire

r is the distance from the wire at which the field strength is calculated

From the equation, we notice the following points:

  • The strength of the magnetic field is directly proportional to the current in the wire
  • The strength of the magnetic field is inversely proportional to the distance from the wire

Therefore, the only correct option in the list is

a. the larger the current, the larger the magnetic field

The howler monkey is the loudest land animal and, under some circumstances, can be heard up to a distance of 8.9 km. Assume the
Airida [17]

Answer:

\frac{I}{I_0}=113.68

Explanation:

P = Acoustic power = 63 µW

r = Distance to the sound source = 210 m

Acoustic power

P=IA\\\Rightarrow I=\frac{P}{A}\\\Rightarrow I=\frac{63\times 10^{-6}}{4\times \pi \times 210^2}

Threshold intensity = I_0=1\times 10^{-12}\ W/m^2

Ratio

\frac{I}{I_0}=\frac{\frac{63\times 10^{-6}}{4\times \pi \times 210^2}}{1\times 10^{-12}}\\\Rightarrow \frac{I}{I_0}=113.68

Ratio of the acoustic intensity produced by the juvenile howler to the reference intensity is 113.68
