Answer 2

Answer :

• 630720000 seconds.

Given :

• 20 years.

To Find :

• The Seconds in 20 Years.

Using Formula :

• $\tt Mutiply \: \: the \: \: years \: \: with \: \: value \: \: of \: \: 1yr$

Example :

• 5 year = ?

• $\underline {\bf \: we \: know \: that\: : } \\ \\ \sf 1min \: = 60sec \\ \sf \: 1hour = 60min \\ \sf \: 1day \: = 24hour \\ \sf \:1year \: = 365 \: days$

• $\sf according \: to \: formula \: : \\ \boxed{\tt \: s \times m \times h \times d} \\ \\ = \sf60s \times 60m \times 24h \times 365d \\ = \sf \: 3600 \times 24 \times 365 \\ = \sf 86400 \times 365 \\ \bf = \: 31536000$

_____Now,___________

• $\sf \: 5yr \: \times \: 31536000 \\ \sf \: \bf= 157680000$

Solution :

• 20 years = ?

• $\sf according \: to \: formula \: : \\ \boxed{\tt \: y \times 31536000} \\ \\ \sf \: 20yr \: \times \: 31536000 \\ \sf \: \bf= 630720000$

Definition :

• Seconds = the second is the duration of 9,192,631,770 periods of the radiation.

• Years = A year is the time taken by Earth to complete its orbit around the Sun. There are 365 days in a year.
