Answer:
a. on the top of Mt Everest
Explanation:
Because the closer you are to the center of the earth, the more powerful the earth's gravity is. The top of Mt. Everest is much farther away from the center of the earth than any of the other places.
Answer:F/L = μ0*I²/2πd
Explanation:
Both wires carries current of the value (I) and are separated by the distance (d).
The length of both wires is (L).
The first wire creates a magnetic field of the magnitude according to Bio-savart law
B=(Uo * I)/2πd
This magnetic field has the ability to exert a force F on the second wire.
This force (F) is given as
F=BIL* sin θ
θ here is 90 because the magnetic field is perpendicular to the length of the second wire.
Thus the value of sin 90 = 1
Hence F= BIL
But B=(Uo * I)/2πd.
We have that F= B=[(Uo * I)/2πd] x IL
Thus we have that F= [Uo* I²/2πd] x L
By rearranging, and bringing L to the left hand side of the equation, we have that
F/L = [Uo* I²/2πd]
Answer:
25 km/h
Explanation:
speed=distance÷time
125÷5=speed
125÷5=25 (then add units)
