Answer:
595.73 X 10⁻⁶ V.
Explanation:
The magnetic field is towards the north with dip angle equal to 65 so the horizontal component of earth's magnetic field will be
H = 50 X 10⁻⁶ Cos 65 = 21.13 x 10⁻⁶ T.
length of rod L = 1.45 M
Velocity of rod = 70 km / h = 19.444 m /s
Since the top of the antenna rod is to have positive polarity , current induced in it will be from down to up . Magnetic field is towards the north .
To cut magnetic flux perpendicularly , rod should move towards the east .
We can easily get this direction by applying Fleming's right hand Rule.
Induced emf = H L v
= 21.13 x 10⁻⁶ X 1.45 X 19.444
= 595.73 X 10⁻⁶ V.
Two 3-ohm resistances in series have 6 ohms of resistance. The battery makes no difference. They don't even have to be in a circuit at all ... the two resistors could be in a box on the shelf. If they're connected in series, then they make 6 ohms.
