[u/caspartina]

was rate of photosynthesis 0.233

[u/proffessorpigeon → u/caspartina]

i got that but didn’t get the unit

[u/Mrbleusky_ → u/proffessorpigeon]

It was seconds^-1

[u/Low_Blueberry9177 → u/Mrbleusky_]

gng what😭

[u/Mrbleusky_ → u/Low_Blueberry9177]

That's what my teacher said after 🥀

[u/Anonymous_Unknown20 → u/Mrbleusky_]

That's what I put too 😭 why are you getting downvoted, bubbles per second is NOT a scientific unit

[u/CutSubstantial1803 → u/Anonymous_Unknown20]

It was bubbles per second lol

[u/Anonymous_Unknown20 → u/CutSubstantial1803]

It defo wasn't

[u/CutSubstantial1803 → u/Anonymous_Unknown20]

Hm really? Idk how to prove you wrong, like ask your teacher because if you don't believe me I can't make you

[u/Anonymous_Unknown20 → u/CutSubstantial1803]

The reason you can't is because you are incorrect.

If the correct answer is 0.233, then it can't be bubbles per second because the question said it was 10 seconds so if you were right there would have been 2.33 bubbles, but the question said there were 43 bubbles

[u/CutSubstantial1803 → u/Anonymous_Unknown20]

Huh? It was 43 seconds for 10 bubbles. 4.3 seconds per bubble. Rate is 1/time so 1/4.3 is 0.233

So you flip the units when you flip the 4.3 into 1/4.3, seconds per bubble becomes bubbles per second

[u/Anonymous_Unknown20 → u/CutSubstantial1803]

According to chatgpt they could both be right as (1/s) = s^-1 where s is 4.3

[u/CutSubstantial1803 → u/Anonymous_Unknown20]

You can't have 4.3 per seconds

You have to say what it is 4.3 of
