Aprojectile is launched horizontally off a cliff. if the projectile is launched with more velocity, the time it spends in the air will

If the projectile is launched horizontally the time it remains in the air will remain constant even if we increase the horizontal velocity.

Explanation:

The vertical displacement will be the same irrespective of the horizontal velocity assuming the projectile is launched from same height. The formula for vertical displacement is given by:

where, y = vertical displacement, t = time,

g = acceleration due to gravity,

= Initial vertical velocity

Since, projectile is launched horizontally, therefore

so the equation becomes

The above equation shows that time spend in air is not dependent on horizontal launched velocity as there is no horizontal velocity in the formula therefore the time in air will remain constant even if we increase the horizontal velocity.

the plateau is likely to turn into a desert do to corrosion.

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.
