Answer:
a
The current that would be produced is
b
Yes this arrangement can be used to cancel out earths magnetic field at points well above the Earth's surface.This is because this current loop acts as a magnetic dipole for point above the earth surface
c
No this arrangement can not be used to cancel out earths magnetic field at points on the Earth's surface .this because on the earth surface it shifts from its behavior as a magnetic dipole
Explanation:
From the question we are told that
The magnetic moment of earth is
The radius of earth generally has a value of
Magnetic moment is mathematically given as
A is the area of the of the earth(assumption that the earth is circular ) and this evaluated as
Now making the subject in the above formula
Answer:
500 cm
Explanation:
Diameter of Milky Way =
Here, this distance is equal = 25 cm
Distance between the Andromeda galaxy and Milky Way is 2 million ly
Hence, the plates would be 500 cm apart
answer
60.1667
explanation
there are four main kinematic formulas that we use in physics
= final velocity
= initial velocity
a = acceleration
t = time
x = displacement
we use an equation based on what information we have
in this question, we have initial velocity (0), final velocity, (38), displacement (12), and we want to find acceleration
so we use the equation that includes
which is this equation
rearrange to solve for a
