Answer:
1.59 Tesla per second
Explanation:
Given that
Radius of the conductor loop, r = 1 m,
Maximum induced emf to the loop, e = 5 V,
We take an assumption, we assume that the rate which the magnetic field is changing is dB / dt.
We then go ahead to apply Farady's law of electromagnetic induction
e = rate of change of magnetic flux
e = dФ /dt
e = A * dB / dt, on substituting we see that
A = πr²
A = π * 1²
A = π, plug in the value for A
5 = 3.14 * dB / dt
dB / dt = 5/3.142
dB / dt = 1.59 Tesla per second
Answer:
magnitude

Direction
Opposite to the velocity of aircraft
Explanation:
As we know that the initial speed of the aircraft when it land on the ground is

now the final speed of the aircraft when it covers 705 m on runway is given as

so here we know that

so now we can say that



It has to be used because you can not visually see them
Answer:

Explanation:
Here two charges are placed at distance "d" apart
now the net value of electric field at some position between two charges will be ZERO
so we will have
electric field due to charge 1 = electric field due to charge 2

Let the position where net field is zero will lie at distance "r" from q1

now we will have

now square root both sides

now we have

so we have
