Answer: [tex]1\text{ year}=8.76\times10^3\text{ hours}[/tex]
Step-by-step explanation:
Given: [tex]\text{1 hour}=3.6\times10^3\text{ seconds}[/tex]
[tex]\\1\text{ day=24 hours}...................(1)\\\text{1 year = }3.65\times10^\text{ days}[/tex]
[tex]\\\Rightarrow\ 1\text{ year}=3.65\times10^2\times24\text{ hours}...........(\text{ from (1)})\\\Rightarrow\ 1\text{ year}=3.65\times24\times10^2\text{ hours}\\\Rightarrow\ 1\text{ year}=87.6\times10^2\text{ hours}\\\Rightarrow\ 1\text{ year}=8.76\times10^3\text{ hours}................\text{In scientific notation}[/tex]
Hence, [tex]1\text{ year}=8.76\times10^3\text{ hours}[/tex]
