The one with the larger mass would pull the halved mass one toward it
As the moon gets further and further away, the gravitational force between the Earth and the Moon decreases. Because the Moon is not being attracted but being pushed away from the Earth. If the gravitational force would have increased, the moon would come closer and closer to the Earth.
Tidal waves
nothing. It is impossible for that to happen. They are both the same things.
Nebula are an accumulation of gas particles. Bearing in mind that there untold billions of atoms in the cosmos. Any two atoms have a gravitational attraction between them. they come together, thus attracting more gas particles by gravitational attraction. These gas particles become so crowded that they begin to glow, (the nebula). The analogy, is a dance hall/disco; maybe two people will statr to dance. Eventually a lot more people arrive on the dance floor, and it becomes hot and crowded. Under further gravitational attraction these hot crowded gas particles keep accumulating into a hot glowing ball. Because partiucles are now so crowded nuclear fusion starts, and releases energy. Hence a Star/Sun. Because this process takes billions of years we do not instantaneously see it going on. NB All stars are nuclear reactors in space.
there is nogravity on moon so it will not go down
The force will increase fourfold.
It will also be halved as circumference = 2Ï€r
Nothing, the force in question IS gravitational attraction.
the attraction between the electron and the protons has to be broken
It will be a quarter of what it was.
The wavelength would double.
There will be a force of attraction between them.
circumference would be halved, area would be one fourth of original , andvolume would be one eighth of original.
Kinetic energy will also be halved. Because kinetic energy is equal to 1/2 mv2
Nothing. But the current is halved.
If you removed energy from neon gas, there would be a decrease in motion and more attraction between the particles.
It is halved. 48/12 = 4 48/24 = 2
