The concept to solve this problem is related to the relativistic physics for which the speed of the object in different frames of reference is related. This concept is called Velocity-addition formula
and can be written as,
Where,
u = Velocity of a body within a Lorentz Frame
v = Velocity of a second frame
u'= The transformed velocity of the body within the second frame
c = speed of light
Replacing we have to
Therefore the meteor moving with respect to the Earth to 230'700.000m/s
D) GPS, because it uses satellites that provide position and velocity data <span>

The resistance of a wire is given by
where
is the resistivity of the material, L the length of the wire and A its cross-sectional area.
In the problem,
and L remain the same, while A changes because the radius changes. The area is given by:
This means that if we double the radius (2r), the area becomes
And therefore, the new value of the resistance is
So, when the radius is doubled, the resistance becomes
of its original value.
