Question

How many years older will you be 1.00 gigasecond from now? (Assume a 365-day year.)

Short answer

You will be 31.7097 years old from now at 1 giga second.

Step-by-step solution

Determining 1 giga second

Here,

In Physics there are many value which are very big when we write it into standard unit form. Like mass of earth in kg or distance between two galaxies in km.

To make this quanity easy to write we use preface numbers which is multiple of ${10}^x$. Here the value of x can be 3, 4, 9 etc

1 giga means ${10}^9$, 1 mega means${10}^6$

Given data

Time given = 1 giga second

= 1 x ${\mathbf{10}}^{\mathbf{9}}$Second

Calculation of year in 1 gigas second

In one day there are 24 hours. In each hour we have 60 min. Each 1 minutes are made of 60 seconds. So it can be said that in 1 day thereare 24 x 3600second.

Such 365 days will be there in a year so ..

Number of second in 1 year

= 3600 x 24 x 365

=31536000 Second

1 year old in 31536000 Second

? year old in 1000,000,000 Second

Number of year in1 giga second=$\frac{1000,000,000}{31536000}$

Number of year in 1 giga second=31.7097 years

Therefore it is concluded that you will be 31.7097 years old from now at 1 giga second.
