Sunita, a Science student, was coming from school to her home. On the way she saw prayers were being done at various place. From Yamuna bridge she saw many people were taking dip in the Yamuna river. When she reached home, she was hungry. She asked her mother to give food, but she refused syaing solar eclipse is occurring and would not cook food till eclipse get over. When she tried to take milk, she found Tulsi leaves in it. Mother again disallowed her to eat or drink anything till the eclipse is completed. She tried to perceive her mother that solar and lunar eclipse are the natural phenomenon and has no ill effect on anyone. But she was not ready to listen anything and advised her not to be unorthodox. She became frustrated and felt embrassed at the superstitions of people and went to study.
a.  What are the values shown by Sunit?
b. Time period of a planet around the Sun is 11.6 years. How far is the planet from Sun? The distance between Sun and earth is 1.5x108 km.

Dear student,
Sunita was unorthodox and was more inclined towards Science.
Tp= 11.6 yrTe = 1 yrre = 1.5×1011T2 = kr3Tp2Te2=r3pr3erp=(TpTe)2/3×rerp=(11.61)2/3×1.5×1011rp=7.68×1011m
