9. In result we analyze and summarize and ask if the hypothesis was correct.
10. Something that changes or varies in an experiment is called variable.
Ans:
Conclusion
Observation

Variable
Protons = atomic number = 11
electrons = proton number = 11
neutrons = mass number - atomic number = 23-11 = 12
The transfer of energy that occurs when a force is applied over a distance is WORK.
Hope this helps!
Convert mole to gram by multiplying the molar mass of sodium
0.500mol Na x 22.990g = 11.495g of Na
Explanation:
It is given that,
The time period of artificial satellite in a circular orbit of radius R is T. The relation between the time period and the radius is given by :
The radius of the orbit in which time period is 8T is R'. So, the relation is given by :
So, the radius of the orbit in which time period is 8T is 4R. Hence, this is the required solution.
