To the Earth in less than ten minutes.
Answer:
It covers distance of 9.15 football fields in the said time.
Explanation:
We know that
Thus distance covered in blinking of eye =
Thus no of football fields=
Answer:
The Flemings left hand rule is used to find the magnitude of a magnetic force
Explanation:
Fleming's left hand rule states that if the first three fingers are held mutually at right angles to one another, then the fore finger points into the direction of magnetic field the middle finger in the direction of current while the thumb points in the direction of force.
Mathematically
Magnetic Force F= BILsinθ
Where
B= magnetic field density Tesla
I= current
L= length of conductor
θ= angle of conductor with field
Resistance = (voltage) / (current)
Resistance = (6.0 v) / (2.0 A)
Resistance = 3.0 ohms
