Is my billing method correct?
So I calculated 750cos(85) and 750sin(85) and got:
750cos(85) = 65.4
750 sin(85) = 747.1
I have given the following task or list. To do this, I am now asked to calculate the maximum speed at which the piston moves downwards. What's the best way to proceed here? Unfortunately, I don't have any idea how to do it.
Hi! The fuel rods filled with uranium hexafluoride tablets are "put" into the reactor as fuel elements, where nuclear fission then takes place by slowing down neutrons – as far as I understand. 1) Isn't hexafluoride already highly radioactive? 2) Why isn't nuclear fission possible in the fuel elements alone? (Because neutrons move too fast?)…
Hello, I have to give a presentation on photovoltaics and have two questions: 1.Can photovoltaic systems/panels also be called solar systems/modules or does the term solar only refer to solar thermal systems? 2. What type of energy do PV systems use: radiant energy, simply solar energy or light energy and what type do solar collectors…
Hello, I have to prepare a presentation on the topic of wave wheels in physics with my group. My task is to research application examples from everyday life and from technology for the wave wheel. So far, I have only found a bicycle as an example on the Internet. Are there any other examples you…
No, that’s not true. The units must not be left in physics, otherwise the bill does not say anything at all.
So if a number is to mean so much Newton, then the sign for Newton must also stand there.
This also applies to angles. If an angle is meant in the angle unit degree, then you have to write the small ring. If you leave it away, you say that you mean the angle not in degrees, but in arc size and then the number means another, much larger angle.

Finally, you also have to describe which force component the two results are, that is, the horizontal and the vertical component.
That might sound pinching, but if you stick to these rules, make it easier for yourself. At the latest, you will notice it! 🙂
Yeah, that’s right. If the arguments are of sin and cos degrees (which is to be assumed here).
