Plz me with my science

when you throw a ball straight toward another person during a game of catch, why does it follow a parabolic path instead of following a straight, horizontal path?

a.
because not enough potential energy exists for the ball to reach its mark.

b.
because the catcher has too little universal gravitational attraction for the ball.

c.
because gravity is the only continuous force acting on the ball.

d.
because, while two continuous forces are acting on the ball, gravity is the strongest.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
