Sl. No.	Unit	Value in Seconds
1.	1 Minute	60
2.	1 Hour	3,600
3.	1 Day	86,400
4.	1 Month	2,600,000
5.	1 Year	32,000,000
6.	10 Years	3,20,000,000

Answer 1

1. 1 minute = 60 s

= 60 × 10¹ s

= 6 × 10¹ s

2. 1 hour = 3,600 s

= 36 × 10² s

= 3.6 × 10 × 10² s

= 3.6 × 10³ s

3. 1 day = 86,400 s

= 8.64 × 10² s

= 8.64 × 10² × 10² s

= 8.64 × 10⁴ s

= 8.6 × 10⁴ s

4. 1 month = 2,600,000 s

= 26 × 10⁵ s

= 2.6 × 10 × 10⁵ s

= 2.6 × 10⁶ s

5. 1 year = 32,000,000 s

= 32 × 10⁶ s

= 32 × 10⁶ s

= 3.2 × 10 × 10⁶ s

= 32 × 10⁷ s

6. 10 years = 320,000,000 s

= 32 × 10⁷ s

= 32 × 10 × 10⁷ s

= 3.2 × 10⁸ s
