∙ 12y agoIt is "required" in the sense that an electron leaving a photo-electric metal "must" have a stopping potential. However, measuring the stopping potential -- the size of the voltage that will perfectly match the energy of such an electron -- gives results that can only be explained by the existence of photons.

Einsteins equation of photo electric effect?
1. hv=hvo + 1/2mvo2here h= plank's constantv= cut off wavelengthvo=cut off frequencym= massvo=stopping potential
Does friction affect stopping distance?
Yes, friction affects stopping distance. The greater the friction the lower the stopping distance; the lower the friction the greater the stopping distance.
What is the stopping time for 30 mph?
Stopping Distance = about 75 feet.
How the steepness of a slope affects stopping distance?
The steeper the slope, the longer the stopping distance is.
How is energy stored in a compressed spring?
The matter in a spring is in a form that wants to bend back into shape when bent. This is called elasticity. When you compress the spring, it wants to spread itself out again, but because you won't let it, it has that energy stored inside of it, waiting to be used. This kind of energy is called potentail energy. Potential energy can exist for two main reasons... if something is above the ground and something is stopping it from falling, it will have potential enrgy. The energy it had to fall is waiting to be used as movement or kinetic energy. This is gravitational potential energy. The spring had potential energy of postion, so the position it was in had potential energy. When you release he spring, it will let out the enrg as movement. The farther you compress the spring, the more energy it will have.
On a motorcross bike the FRONT brake supplies how much of the potential stopping power?
65% - 75%
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
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.

Why are kenetic and potential energies the same?
they are not the same. kinetic energy is energe that an object has due to its motion. potential energy is stored and held in the readiness. for example kinetic energy would be like a bowling ball knocking over bowling pins. unlike kinetic energy, which is the energy of motion, potential energy is stored and may be used later on like a car stopping at a red light.
Does friction affect stopping distance?
Yes, friction affects stopping distance. The greater the friction the lower the stopping distance; the lower the friction the greater the stopping distance.
On a Motocross bike the front brake supplies how much of the potential stopping power?
between 60 - 75%. Depends on how much weight is biased toward the front wheel and how much brake pressure is applied.
What is the distance your vehicle travels while stopping?
This distance your vehicle travels while stopping is?total stopping distance
How do you say stopping in Spanish?
"to stop" is "parar"... if you want to say "I am stopping" it is "estoy parando." "we are stopping" is "estamos parando"
