Asoftball is hit over a third baseman's head with some speed v0 at an angle θ above the horizontal. immediately after the ball is hit, the third baseman turns around and begins to run at a constant velocity v=7.00m/s. he catches the ball t=2.00s later at the same height at which it left the bat. the third baseman was originally standing l=18.0m from the location at which the ball was hit. find the angle and vo.

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 duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

the answer should be in the picture.
