Answer:
F = 1.2 10⁵ N
Explanation:
Force is defined by
P = F / A
F = P A
The area is
A = π r²
the radius is half the diameter
r = d / 2
A = π d²/4
we substitute
F = P π d²/4
let's calculate
F = 145 10⁶ π (3.25 10⁻²)²/4
F = 1.2 10⁵ N
Answer:
The rotation of Earth on its axis causes electric currents to form a magnetic field which extends around the plane
Explanation:
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents.
