Adeer is running from a mountain lion when it encounters a fence that is 1.50 m high. seeing the fence, the deer jumps, leaving the ground at a speed of 13.0 m/s and angle of 29.0º when it is a distance of 2.50 m from the fence. (a) by how much does the deer either clear or miss clearing the fence? (b) just before reaching the fence, is the deer rising or falling through the air?

Explanation:

Given

Initial Velocity (u)=13 m/s

angle

distance between fence and deer=2.5 m

We consider deer jump similar to projectile motion

equation of trajectory

Thus deer will cross the fence with an difference in its jump and fence

1.5-1.148=0.351 m

so deer rises during when it is over fence

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

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.
