Physics homework?
Can someone help me with my physics homework? I don't understand the 20.
Thank you!

I've done tasks a) and b), but I don't understand task c). Why does spring stiffness depend on the length?
Can someone tell me where these 8V come from for the Kps
So momentary or still tied to the theory of relativity?
Does the solubility of solids in water depend on pressure? If I dissolve sugar in water at 1 bar at 50˚C, can I dissolve the same amount at a lower temperature with less air pressure? After all, the molecules are separated by a greater distance.
The table value for the molar enthalpy of vaporization of water refers to the normal boiling point at 100°C and is 40.7 kJ/mol. But why do we need this 40.7 kJ/mol when the boiling point has already been reached, at which the vapor pressure corresponds to normal atmospheric pressure? At that point, the water already…
Speed is distance per time. So see how much distance has been traveled in what time (the gradient of the straight line, Delta s / Delta t)
