Which expression is dimensionally consistent with anexpression that would yield a value for time-1? (v is velocity, x is distance, and t istime)
a. v/x
b. v2/x
c. x/t
d. v2/t
e. x/v

Explanation:

Here we need to find an expression that would yield a value for time⁻¹

We know that

              Velocity = Displacement ÷ Time

              v = x/t

Option A :

               Option A is correct

Option B :

               Option B is not correct

Option C :

               Option C is not correct

Option D :

               Option D is not correct

Option E :

               Option E is not correct

Option A is the correct answer.

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

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.
