Answer:

Acceleration will be equal to 3689.16m/sec^2

Explanation:

We have given initial height h = 1 m

Time instant t = 1.2 m-sec = 0.0012 sec

Initial velocity u = 0 m/sec

From third equation of motion we know that v^2=u^2+2gh

So v^2=0^2+2\times 9.8\times 1

v = 4.427 m/sec

We have to find the acceleration

Acceleration is time rate of change of velocity

So acceleration a=\frac{v}{\Delta t}=\frac{4.427}{0.0012}=3689.16m/sec^2

So acceleration will be equal to 3689.16m/sec^2

What is the main determining factor in defining boundaries between layers of earth's atmosphere?
konstantin123 [22]
The main determining factor in defining boundaries between layers of earth's atmosphere would be temperature changes in these layers. Temperature is one essential property that varies in the atmosphere. Based from this variation, the atmosphere is divided into four major layers and further to three smaller layers -  troposphere, tropopause, the stratosphere,  stratopause, the mesosphere, mesopause, and the thermosphere.The troposphere is the layer that is nearest to the surface of the Earth. It is the part where humans, plants and animals survive. Also, it is the warmest layer of the atmosphere. And as we go higher the atmosphere, the temperature would drop making it much cooler.

The table below shows the right ascensions of two stars at a location.
noname [10]
Star 1 - 4 hours right ascension
 Star 2 - 3 hours right ascension
 Subtracting hours right ascension
 4 hours right ascension - 3 hours right ascension = 1 hours right ascension.
Thus,
 star 1 will rise 1 hour before star 2
