How do you write in scientific notation ?

Click For Summary
To express SI units in scientific notation, a common format is to use curly braces or square brackets. For example, one can write {time} = s or v [m/s] = d[m] / t[s] to denote units succinctly. This notation helps clarify the relationship between physical quantities and their respective units. The use of brackets or braces is widely accepted in scientific writing for clarity. Overall, adopting these conventions can enhance the readability of scientific expressions.

How do you write in scientific notation "the (SI) units of x are..."?
For example, the SI units of time are seconds. Is there any succinct way I can write this? Maybe it's like this:

{time} = s

?

I've seen peopel use square brackets to denote "units of"

v [m/s] = d[m] / t
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
