How do you find stopping potential?
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 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.
What is the stopping time for 30 mph?
To calculate stopping time, you need to know the deceleration rate of the vehicle. Without this information, it is impossible to determine the stopping time accurately. Different vehicles will have different stopping times at the same speed depending on their deceleration capabilities.

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.
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 are the safety considerations and potential risks associated with riding a fixed gear bike with no brakes?
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.
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.
Is ringing in the ears a potential side effect of quitting smoking?
Generally not. If ringing in the ears has occurred at the same time as stopping smoking, this is more likely to be concidental than not.
What is a sentence with the word stopping?
The stopping distance is increased on wet roads.There was no stopping the killer.The plane will be stopping at Dubai airport for refuelling.
