A woman with mass m is standing on a platform and holding onto a light rope attached to a hook in the ceiling. A second rope, also attached to the hook, is being held by a man with larger mass M on a second platform. The ropes are the same length, and the ropes are initially horizontal. The two people start from rest and swing toward each other. They meet at the lowest point of their swings, and grab onto one another, swinging upward until the ropes make an angle of 28.9° with the vertical. Find the value of the ratio m M .

are there options? cause you ain’t. real specific

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
