Answer:

The correct option is b

Explanation:

Generally the induced voltage in an inductor is mathematically represented as  

        V = L *  \frac{\Delta I }{\Delta t}

Now  \frac{\Delta I }{\Delta t}  is the change in voltage with respect to time , when this is zero i.e when the current is not changing(what this means is when current is constant ) the induced voltage becomes    

        V = L * 0

=>     V = 0 \ V

Hence if the current is not changing with respect to time there will be no induced voltage

Considerable scientific work is currently under way to determine whether weak oscillating magnetic fields such as those found ne
slega [8]

Answer:

\epsilon = 2.96 \times 10^{-11} \ V

Explanation:

given,

magnetic field strength =  1.40 ✕ 10⁻³ T

frequency of oscillation = 60 Hz

diameter of RBC = 7.5 μm

EMF = ?

\epsilon = NBA\omega

\epsilon = NB(\pi\ r^2)\ (2\pi f)

\epsilon = NB(\pi\ (\dfrac{d}{2})^2)\ (2\pi f)

\epsilon = (1)\ 1.4 \times 10^{-3}(\pi\ (\dfrac{7.5 \times 10^{-6}}{2})^2)\ (2\pi\times 60)

\epsilon = 2.96 \times 10^{-11} \ V

maximum emf that can generate around the perimeter of the cell \epsilon = 2.96 \times 10^{-11} \ V

A 10248 kg car is pulled by a low tow truck that has an acceleration of 2.0m/s what is the net force on the car
Ksenya-84 [330]

Answer: 20496N

Explanation:

The formula to calculate the net force will be given as:

Net force = Acceleration × Mass

Since 10248 kg car is pulled by a low tow truck that has an acceleration of 2.0m/s, the net force would be:

= 10248 × 2

= 20496N
