The stopping potential can be found by measuring the maximum kinetic energy of the emitted photoelectrons and then using the equation KE = eV, where KE is the maximum kinetic energy, e is the charge of an electron, and V is the stopping potential. By rearranging the equation, the stopping potential can be calculated as V = KE/e.
The stopping potential is negative because it represents the work done by the stopping voltage to prevent the electrons from reaching the anode. This negative potential halts the kinetic energy of the electrons, causing them to return to the cathode.
The stopping potential is the potential (energy/unit charge) or (Joules/Coulomb) that must be applied to stop the electrons from being ejected from the surface when the light is shone on it.
The stopping potential formula is V hf/e, where V is the stopping potential, h is the Planck constant, f is the frequency of the incident light, and e is the elementary charge. This formula is used to calculate the minimum voltage needed to stop the emission of electrons in a photoelectric experiment.
The stopping potential equation is V hf - W, where V is the stopping potential, h is the Planck constant, f is the frequency of the incident light, and W is the work function of the metal surface. This equation is used to calculate the minimum voltage needed to stop photoelectrons emitted from a metal surface.
Retardation can be found by dividing the change in velocity (initial speed minus final speed) by the stopping time. Retardation represents the rate at which an object slows down.

65% - 75%
The stopping voltage where the current goes to zero is proportional to the KE of the electron. Simply detecting a photocurrent doesn't tell you the electron's energy. You could try and find the photon energy where the PEE just barely works, but what if you don't have a continuously-tunable light source? (which most people don't). But a retarding potential is easily tuned.
65 to 70 % depending on the type of pad material (late models only) Frt brakes are for stopping, rear brakes are for slowing.
you're a tool. dependant upon inertia, stopping surface, braking potential, weight. lots of factors. a car may have ABS or not. this affects the final distance
Riding a fixed gear bike without brakes can be risky because you have less control over your speed and stopping. Safety considerations include the need for advanced bike handling skills, increased risk of accidents, and the potential for collisions. It is important to be aware of your surroundings, anticipate potential hazards, and always have a plan for stopping safely.
It doesn't, from the equation E = h*f (E is energy, h is Planck's constant, f is frequency) you can clearly see that energy is a function of frequency, not amplitude (intensity). Therefore, it doesn't even matter what the relationship between stopping potential and energy is, because it will only depend on frequency, which is sufficient knowledge to answer this question.
I need to find that out to and it is 2020 :(
stopping to ask,and starting to find or discover about what they donot know.
