What is the correct way to express a temperature interval in degrees Celsius?

AI Thread Summary
The correct way to express a temperature interval in degrees Celsius is debated, with options including C°, °C, and a subtraction format. According to a referenced Wikipedia article, both C° and °C are acceptable for temperature intervals. However, clarity is emphasized, suggesting that the distinction between temperature values and intervals is important. The final answer may depend on specific instructor or textbook preferences. Ultimately, for accuracy, it is advisable to consult educational materials for the preferred format.

A particular temperature interval, as opposed to a particular temperature value is written (a) C°, (b) °C, (c) degrees celcius minus degrees celcius (d) it makes no difference.

I am unsure as to what the question is asking.

Ooops I forgot to type in the option for c. After reading the link above provided by a PF member It says that options a and b can both be used. Therefore the answer to this question is then D. Is this correct.

It really depends on your instructor or textbook and how fussy they want to be. If you wanted to be as clear as possible, how would you write a temperature interval?
 
Just to add: Since the question calls attention to a distinction between an interval and a temperature, I suspect they want you to choose which is most accurate. Otherwise why bring it up at all? (But see what your book says.)

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
