Answer: A tidal force is related to gravity, but it isn't the same thing. It's really the difference between the the strength of gravity at two locations. The gravitational attraction between two objects (say the Earth and the Moon) decreases with distance.

The tidal force acting on an astronomical body, such as the Earth, is directly proportional to the diameter of that astronomical body and inversely proportional to the cube of the distance from another body producing a gravitational attraction, such as the Moon or the Sun.

Answer:

Gravity is the force that keeps us standing. It keeps us from floating, like you do when you are in space, away from gravity.

Tidal Force - The tidal force is a force that stretches a body towards and away from the center of mass of another body due to a gradient (difference in strength) in gravitational field from the other body

Hopefully this helps!!! ;)

The magnets point North when the Earth's magnetic field has (p2)<br><br>need some help :)

<h2><u>EARTH'S MAGNETIC FIELD</u></h2>

The magnets point North when the Earth's magnetic field has?

<h2><u>ANSWER</u></h2>

I think the best answer for this question is Magnetic Reversal or Geomagnetic Reversal.

In geomagnetism, the term "geomagnetic reversal" also known as 'flip', is the process by which the North pole becomes South pole and the South pole transforms into North pole.

<h2><u>THE MAGNETIC REVERSAL</u></h2>

The reversals happen on rare occasions when iron molecules start moving towards the opposite direction as other iron molecules around them within the Earth's spinning outer core.

What would happen if we didnt have mitochondria ? ( paragraph)

slamgirl [31]

Basically, the cell wouldn't be able to "breathe," as the mitochondria is where the respiratory functions of the cell happens. No energy would be produced, and then the cell would stop moving and die.
