Calculate the number of seconds in a day, a week, and a month, stating the answers using SI prefixes.

Here are the solutions to the numerical problems:

.1: Calculate the number of seconds in a (a) day (b) week (c) month and state the answers using SI prefixes.

a) Seconds in a day:

Step 1: Convert days to seconds.

$$1 \text{ day} = 24 \text{ hours} \times 60 \text{ minutes/hour} \times 60 \text{ seconds/minute}$$ $$1 \text{ day} = 86400 \text{ s}$$

Step 2: Express in scientific notation and apply SI prefix (kilo, k = $10^3$).
