I think it is a, b, and e. Hope it helps! :)
For Part A.
The absolute value of vector A is
<span>|A | = 6
This is simply the square root of the sum of the squares of the coordinates.
For Part B
Do the same thing as in Part A
| B | = </span>√14
<span>
Part C
Simply subtract the corresponding elements resulting in
(-3, 2, 7)
Part D
</span>√62
<span>
Part E
Yes</span>
C
The wavelength of the light produced by the laser is determined by the Composition of the active medium
Explanation:
As stipulated by Bohr's theory, different atoms have different and unique absorption and emission spectra that can also be used to identify them. The electrons of the atoms when excited (the enter an inversion state), using specific photons of electromagnetic waves, they move up energy levels. When the electrons move back to their ground state, they release the same wavelength of photons. The photos then excite other atoms and the amplification continues. Therefore the lasing medium is the main determinant of the wavelength of the laser beam.
For example, the use of argon fluoride as an active medium produces lasers of 193 nm in wavelength and the use of nitrogen produces laser of

Answer:
Only magnetic field present
Explanation:
Since, the positively charged particle does not speed up or slow down, but it does deflect in the downward direction. This means only magnetic field is present.
This is because electric field changes the velocity and magnetic field changes the direction.
The magnetic force F is given by
F = qvBsinθ
Where, q = charge magnitude, v = velocity of charge, B = strength of magnetic field. and θ =the angle between the directions of v and B.
