AI Thread Summary
To determine the number of electrons emitted from the cathode each second, one can divide the number of photons striking the cathode per second by the charge of an electron, approximately 1.6 x 10^-19 coulombs. However, the resulting number may not seem realistic, indicating potential issues with the calculations or assumptions made. Understanding the current between the cathode and anode can also provide valuable insight into the electron emission rate. The user is seeking clarification on the appropriate equations and methods to accurately calculate this value. Accurate calculations are essential for a correct understanding of electron emission in this context.

Hi all, I realize the subsequent question is likely to be quite simplistic; therefore I apologise in advance and I hope I am not offending fellow users. Here’s the question: “How many electrons are emitted from the cathode each second?”
How would I go about answering this question?

I have previous calculated the energy of a photon and the number of photons striking the cathode each second.

Thank you in advance for any help provided :)

Homework Statement


Here’s the question: “How many electrons are emitted from the cathode each second?”
How would I go about answering this question?
I have calculated the energy of a photo using E=hf and I also have calculated the number of photons striking the cathode each second.



Homework Equations


I am not sure of the equation for this problem as I am unable to locate it in my current Physics literature/I have also been unable to locate a relevant equation on the internet.


The Attempt at a Solution


Would I divide the number of photons striking the metal per second by the charge of an electron? Therefore: (number of photons striking cathode each second)/1.6*10-19...

The numebr I obtain doesn't seem very realistic ;\.

Thank you :).

Do you know the current between the cathode and anode?

Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
