How many seconds in 16 years? (Ignore leap years). show work

There are 504,576,000 seconds in 16 years.

Explanation:

To calculate the number of seconds in 16 years, let's first use simpler units since we are going to be working with large numbers.

First, calculate the number of seconds in one day (24 hours). We can do this with the common knowledge that there are 60 seconds in a minute, and 60 minutes in an hour, multiply the seconds and minutes:

Therefore, there are 3600 seconds in an hour. Since we know that there are 24 hours in a day, we can multiply the seconds by hours:

Therefore, there are 86,400 seconds in a day.

Knowing that there are 365 days in a year, we can multiply 86,400 seconds by 365 days to calculate the number of seconds in a year:

Therefore, there are 31,536,000 seconds in a year.

Since the question is asking the number of seconds in 16 years, we can simply multiply 31,536,000 seconds by 16 years:

Therefore, there are 504,576,000 seconds in 16 years.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³
