Learning Goal: To practice Problem-Solving Strategy 30.1 Electromagnetic Induction. A coil of wire contains N turns and has an e

Helen [10]

Answer:

Time interval for which magnetic field reduced to ZERO is given as

$t = \frac{NB_0\pi a^2}{RI}$

Explanation:

As we know that the flux linked with one coil is given as

$\phi = B_0 A$

$\phi = B_0(\pi a^2)$

now total flux of all coils is given as

$\phi = NB_0\pi a^2$

now let say the flux is reduced to ZERO after time "t"

so as per Faraday's law EMF induced in the coil is given as

$EMF = \frac{NB_0\pi a^2 - 0}{t}$

now the current in the coil is given as

$I = \frac{EMF}{R}$

$I = \frac{NB_0\pi a^2}{Rt}$

so the time interval is given as

$t = \frac{NB_0\pi a^2}{RI}$

How are the variables speed and velocity different? how are they similar

victus00 [196]

Answer:

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.
