P=F/A
Force= P * A = (2000 x 3) N = 6000N
Explanation:
A=b+d that is the way to rewrite the equation
Answer:
Lithium
Explanation:
The equation for the photoelectric effect is
where
is the energy of the incident photon, with
h being the Planck constant
c is the speed of light
is the wavelength of the photon
is the work function of the metal (the minimum energy needed to extract the photoelectron from the metal)
is the maximum kinetic energy of the emitted photoelectrons
In this problem, we have
is the wavelength of the incident photon
is the maximum kinetic energy of the electrons
First of all we can find the energy of the incident photon
Converting into electronvolts,
So now we can re-arrange the equation of the photoelectric effect to find the work function of the metal
So the metal is most likely Lithium, which has a work function of 2.5 eV.
Answer:
i think its the golgi body tbh
Explanation:
hope this helps
An educated guess about something. (What might happen in the future)
