Answer:
ΔH = 33.17m
Explanation:
By knowing the amount of time it takes the rocket to travel the horizontal 27m, we will be able to calculate the height when x=27m. So:
where 
Solving for t:
t=0.72s
Now we calculate the height of the rocket:
If the wall was 11m-high, the difference is:
ΔH = 33.17m
En términos simples, una articulación (donde dos o más huesos se unen) forma el eje (o fulcro), y los músculos que cruzan la articulación aplican la fuerza para mover un peso o resistencia. Las palancas suelen estar etiquetadas como de primera, segunda o tercera clase
As it stands, none of the choices is correct.
I have a hunch that you copied either #3 or #4 incorrectly.
One of those ... either choice-3 or choice-4 ... is supposed to say "<u><em>Conductors</em></u> allow electrons to flow through an object by conduction". that would be the correct choice.

depends on what cell you are talking about a cell like a cell phone or a cell like a small room in which a prisoner is locked up or in which a monk or nun sleeps.<span><span>

Please ignore my comment -- mass is not needed, here is how to solve it. pls do the math
at bottom box has only kinetic energy
ke = (1/2)mv^2
v = initial velocity
moving up until rest work done = Fs
F = kinetic fiction force = uN = umg x cos(a)
s = distance travel = h/sin(a)
h = height at top
a = slope angle
u = kinetic fiction
work = Fs = umgh x cot(a)
ke = work (use all ke to do work)
(1/2)mv^2 = umgh x cot(a)
u = (1/2)v^2 x tan (a) / gh
