Arocket initially at rest on the ground lifts off vertically with a constant acceleration of 2.0 ã 101 meters per second2 . how long will it take the rocket to reach an altitude of 9.0 ã 103 meters?

Time taken, t = 30 seconds

Explanation:

It is given that,

Initial speed of the rocket, u = 0

It is lifted with a constant acceleration of,

Height to be attained,

Let t is the time taken by the rocket to reach an altitude of . Using the second equation of kinematics to find it as :

t = 30 seconds

So, the time taken by the rocket to reach given height is 30 seconds. Hence, this is the required solution.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
