Question

(e) What do you understand by the term orbit? What is the shape of the orbit of the Earth?
(f) After how many years would a student born on 29th February celebrate his birthday? Give reasons.​

Answer 1

Answer:

e)An orbit is the path that an object takes in space when it goes around a star, a planet, or a moon. ... For instance: “The earth orbits around the Sun.” The word 'revolves' has the same meaning, but 'rotates' is the spin of the object. Many years ago, people thought that the Sun orbits in a circle around the earth.

f)A person born on February 29 may be called a "leapling", a "leaper", or a "leap-year baby". Some leaplings celebrate their birthday in non-leap years on either February 28 or March 1, while others only observe birthdays on the authentic intercalary date, February 29
