Calculating the Planck Constant: A Helpful Guide for Physics Students

AI Thread Summary
To calculate the Planck constant, use the photoelectric effect equation KE_max = hf - φ, where φ is the work function and KE_max is the maximum energy of emitted electrons. Rearranging this equation allows you to express it in the form of a straight line, y = mx + c, where h represents the slope. By plotting the data from your experiment, you can determine the value of h. Additional guidance may be needed for those unfamiliar with the concepts. Understanding this process is essential for physics students preparing for tests.

Hello,

First time at this site really good.

So on to the point.How can i calculate the Planck constant so i can compare it with the already known number for it??its for a physics test and i can't find out ...

Thnx in advance

You can do this with the photoelectric effect. You know the equation KE_{max} = hf - \phi, where \phi is the work function of the metal and KE_{max} is the maximum energy of the emitted electrons. You need to relate that equation to that of a straight line, ie. y = mx + c, then you can calculate a value for h.
 
Because I am not that good can you help me more.It will save me

thnx
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
