Answer:
moving the circuit or the magnet gives the same result
Explanation:
The faraday effect establishes that the temporal variation of imaginative flow produces an electric potential
fem = dfi / dt
the magnetic flux is
Ф = B. A = B A cos θ
suppose for simplicity that the angle is zero so cos 0 = 1
Φ = B A
By analyzing this expression, the change in magnetic flux can converge while keeping the magnetic field fixed and varying the electric field or keeping the electric field fixed and varying the magnetic field.
Consequently moving the circuit or the magnet gives the same result
Answer:
Explanation:
Speed of van, v = 28 m/s
Radius of unbanked curve, r = 150 m
Let is the angle with the vertical. In case of banking of road,
.............(1)
And
..........(2)
From equation (1) and (2) :
So, the string makes an angle of 28.07 degrees with the vertical. Hence, this is the required solution.
