Yes.
In fact, from the graph we see that the threshold frequency (the minimum energy of the incoming energy needed to extract a photoelectron from the material) is (we see it because this is the frequency at which the maximum kinetic energy of the emitted electron is zero).
The incoming photon in this problem has a frequency of 8.0 E14 Hz, so above the threshold frequency, therefore it is enough to extract photoelectrons from the material.
Answer:
a
x-component
y-component
b
Magnitude
direction is
Explanation:
From the question we are told that
The first vertical distance is
The first horizontal distance is
The second vertical distance is
Generally the displacement is
x-component
y-component
Generally the helicopters displacement is mathematically evaluated as
The direction is the angle the displacement of the helicopter makes with the horizontal which is mathematically evaluated as
