Space shuttle orbiting the earth
Answer:
Explanation:
Exact numbers are those numbers which are known with 100% certainty or accuracy . Numbers having decimal are generally not exact because they are a part of long drawn decimal number after rounding off to certain places after decimal.
On the basis of this definition we can say as follows
speed of light is 2.99792 ×108 . Here the number quoted is not an exact number because it is a rounded off figure of speed of light to five digits after decimal .
Similarly density of mercury too is rounded off to two digits after decimal
so it is also not a exact number.
There are 3600 s in 1 h . Here 3600 s is an exact number because one hour has been defined as 3600 s . It is not measured by any instrument.
In 2003, the United States had 50 states. Here 50 is an exact number .
Answer:
follows are the responses to the given question:
Explanation:
The kinetic energy of every object moving. 
any entity lifted against the strength of gravity stores elastic potential of gravity.
Its total power of an independent device stays constant underneath the Mass conservation on Energy and it is, the kinetic energy plus potential energy is just like a fixed 
. So, if KE improves, it is valid that PE declines.
If the PE is now at least then KE has been at the highest. It is also valid that KE is reduced as PE is increased as well as the maximum PE, the minimum KE.
Answer: a tadpole is the first or second step into the evolution for a frog
Explanation: a frog starts with the egg then it becomes a tadpole for 6 to 12 weeks before it can start going out the water.
