Hey, How do I determine the instantaneous rate of change (specifically, the instantaneous current) if I don't have a functional equation? So, let's assume I have some kind of indefinable jumble and am supposed to determine the rate of change in step 5. I have to let x approach 0, but then what?
Hello, I need your help. In the task, the coordinates of the vehicle are described by the following equation: x = -(t)^2 y = 1/3 * t^3 I now need to determine the direction of the vehicle's motion at time t = 2 s. Is the direction then a vector with the first derivatives of…
Hey I've watched a lot of videos about the 4th dimension over the last few days and there's one thing I don't understand and that no one has explained yet. The 4D videos are about the fact that we 3D beings (humans) cannot imagine 4D objects, but can at most see the shadows of 4D…
Hey, I'm studying for a chemistry test but I can't find any solutions for these alkanes and I really need them! Thanks in advance 🙂
Hi, I need to calculate what percentage of an iceberg is underwater. Given the volume (1000 m³) and the density (917 kg/m³), I'm not sure. Please reply quickly, thank you in advance 😉
Hello, can anyone help me with number b? I don't quite understand what the n is.

A small v is common for speed.
A large V is customary for volumes, and U or V is also suitable for potential energy.
Note that you have to do it at speed with a vectorial size. Therefore, the v is often printed with an arrow on it or bold.
In formulae, small letters are usually used.

Little v is right. Large V is usually the volume.
“correct” is always the symbol that is associated with the physical size in the context of a task or publication, for example “an auto moves with the speed v …”
There are no overcrowding symbols except in the head of teachers who always use the same symbols and are too lazy for the context description.
v or a closer name m/s, km/h, …
Small v is correct
It is a small v. The big V is the voltage.
Formula characters and characters for a unit have nothing to do with each other.
I know, but forgot the V for the tension in the German is unusual. In English-language texts this is actually found as a formula mark.
No. V is the short form for volts, the INHEIT of the electrical voltage. Topic missed.
No, much more recently read in English, where the V is also used as a formula for tension.
@Matermace
Voltage would be “u”
U, if so 😉
Thank you, I don’t need to googlen.
You can see how little you use the reading. For this purpose, the large U is used for the voltage, the R for resistors and the I for current strengths. Ohmsh’s law.
