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.

Why stopping potential is negative?
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.
What is stopping potential?
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.
What is the stopping potential formula used to calculate the minimum voltage required to stop the emission of electrons in a photoelectric experiment?
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.
What is the stopping potential equation used to calculate the minimum voltage required to stop photoelectrons emitted from a metal surface?
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.
How do you find retardation if speed and stopping time is given?
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.

On a motorcross bike the FRONT brake supplies how much of the potential stopping power?
65% - 75%
How many feet does it take to stop at 55mph?
The stopping distance at 55 mph varies based on factors like vehicle type, road conditions, and braking efficiency. On average, it takes about stopping distance of stopping distance of 200-250 feet to come to a complete stop, which includes both the reaction distance (the distance traveled while the driver reacts) and the braking distance. If you consider a reaction time of about 1.5 seconds, this adds roughly 120 feet to the total stopping distance.
What is stopping voltage?
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.
How much potential stopping power does the front brake supply on a motocross bike?
65 to 70 % depending on the type of pad material (late models only) Frt brakes are for stopping, rear brakes are for slowing.
What is the overall stopping distance of a car travelling at 100km an hour?
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
What happens to the stopping distance as tyres get old and worn?
I need to find that out to and it is 2020 :(
What are the characteristics of an scientists?
stopping to ask,and starting to find or discover about what they donot know.
How does light intensity affect the stopping potential?
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.
