Question

A lecture period (50.0 min) is close to 1.00 microcentury. (a) How long is a microcentury

Answer 1

52.56 minutes

Explanation:

Time=1 micro century

We have to find the time in minutes

We know that

`1 micro=10^(-6)`

1 centrury=100 years

1 year=365 days

1 day=24 hours

1 hour=60 minutes

1 micro century=
`10^(-6)`century

`10^(-6)` century=
`10^(-6)* 100=10^(-6)* 10^(2)=10^(-6+2)=10^(-4)` year

By using the property
`a^x\cdot a^y=a^(x+y)`

`10^(-4)` years=
`10^(-4)* 365=0.0365` days

`0.0365 days=0.0365* 24=0.876days`

`0.876days=0.876* 60=52.56`minutes

Hence, 1 micro century=52.56 minutes
