Question

The normal duration of I.Sc. Physics practical period in Indian colleges is 100 minutes. Express this period in microcenturies. 1 microcentury = 10−6 × 100 years. How many microcenturies did you sleep yesterday?

Answer 1

Answer:

1 micro century = 10⁻⁶ × 100 years.

= 10⁻⁴ years.

∵ 1 year = 365 days.

= 365 × 24 hours.

= 365 × 24 × 60 minutes.

= 525600 minutes.

∴ 10⁻⁴ years = 525600 × 10⁻⁴

= 52.56 minutes.

Now,

∵ 52.56 minutes is equals to the 10⁻⁴ years (or 1 micro century).

∴ 1 minutes is equals to the 1/52.56 micro century.

∴ 100 minutes is equals to the 100/52.56 micro century.

= 1.902 micro century.

∴ Normal Duration of the I.Sc. Physics Practical Periods in Indian Colleges is 1.902 micro century
