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:
Boron and selenium are important minerals that help your body to form bone and absorb calcium better – helping to support bone health and integrity.

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
![\theta = tan ^{-1}[ \frac{48}{20}]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20tan%20%5E%7B-1%7D%5B%20%5Cfrac%7B48%7D%7B20%7D%5D)
=> ![\theta = tan ^{-1}[ 2.4 ]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20tan%20%5E%7B-1%7D%5B%202.4%20%5D)
=>
