A 64-kg skater initially at rest throws a 5.0-kg medicine ball horizontally to the left. Suppose the ball is accelerated through a distance of 1.0 m before leaving the skater's hand at a speed of 7.0 m/s . Assume the skater and the ball to be point-like, the surface to be frictionless, and ignore air resistance. Use a vertical y-axis with the positive direction pointing up, and a horizontal x-axis with the positive direction pointing to the right.
A) Determine the acceleration of the ball during the throw.
B) Determine the acceleration of the skater during the throw.

where is the circuit diagram ?

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.
