The magnetic north pole of the earth's magnet is in the geographic south pole.
- There are two magnetic and geographic poles each, north and south
- The two geographic poles are the locations where the earth's axis of rotation passes through which is imaginary
- The magnetic north and south poles are not the same as the geographic north and south poles
- In a compass, the needle points to the magnetic north pole
- By convention, the magnetic north pole corresponds to the geographic south pole
- The magnetic south pole corresponds to the geographic north pole
- The magnetic field lines of a magnet start from the magnetic north pole and end at the magnetic south pole
The magnetic north pole of the earth's magnet is the geographic south pole.

Answer:
v = 17.71 m / s
Explanation:
We can work this exercise with the kinematics equations. In general the body is released so that its initial velocity is zero, the acceleration of the acceleration of gravity
v² = v₀² - 2 g (y -y₀)
v² = 0 - 2g (y -y₀)
when it hits the stone the height is zero and part of the height of the seagull I
v² = 2g y₀
v = Ra (2g i)
let's calculate
v =√ (2 9.8 16)
v = 17.71 m / s
The Milky Way galaxy is the one that the sun is a member of, and it contains
our solar system. We're in it, and you can't get much closer than that.
The Milky Way is known to be bigger than your average galaxy, but it's
probably not correct to say that it contains the 'most' stars of any galaxy.
The estimate for the Milky Way is only a few hundred billion stars.
The electrostatic force between two charged object is given by:
where
k is the Coulomb's constant
q1 and q2 are the charges of the two objects
r is the separation between the two objects
We see that the force is inversely proportional to the square of the distance:
. Therefore, if the distance is doubled, the force decreases by a factor 4, and the new force will be:
and it will still be a repulsive force, since the two balloons have charges of same sign.
