The universal gravity formula is <span>F = G(Me)(Mm)/r^2. Lets use this formula to help us calculate what would happen if the Moon was twice as big.
</span><span>Mn = new mass = 2*Mm
</span><span>Fn = G(Me)(Mn)/r^2
</span><span>Fn = G(Me)(2Mm)/r^2
</span>Fn = 2*G(Me)(Mm)/r^2
<span>Fn = 2*F
</span>So 2 times the force it was before. The force should be the same, but you never know the moon and space as well know it can work in very mysterious ways.
Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
If earth was not tilted on a axis, we wouldn't have any seasons. we wouldn't have seasons because the axis tilts us towards or away from the sun, and if you're tilted torwards the sun the sun you would have summer. if you're tilted away from the sun, you have winter. if there was no axis, the temperature would be the same all around the earth, so therefore we would not have seasons.
hopefully this helps
<h2>
The rank is : .</h2>
We need to rank the objects according to the magnitude of their momentum.
We know momentum ,{ here m is mass and v is velocity }
Momentum of object A ,
Momentum of object B ,
Momentum of object C ,
Now, we can rank them in order of their magnitude of momentum .
.
Hence, this is the required solution.
