If Voq doubles, abN gets multiplied by 16 .
If Voq=3, abN=81 .
(a) The average speed must you have for the second half of the trip to meet your goal is 8 km/h.
(b) The value obtained (8 km/h) is not reasonable for the second half of the distance since the first half is 48km/h.
<h3>
What is average velocity?</h3>
Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs.
average velocity = total distance / total time
v = (d)/(0.5d/v₁ + 0.5d/v₂)
where;
- v is the average velocity
- v₁ is the average velocity during the first half
- v₂ is the average velocity during the second half
90 km/h = (d) / (0.5d/48 + 0.5d/v₂)
90(0.5d/48 + 0.5d/v₂) = d
0.9375d + 0.5d/v₂ = d
d(0.9375 + 0.5/v₂) = d
0.9375 + 0.5/v₂ = 1
0.5/v₂ = 0.0625
v₂ = 0.5/0.0625
v₂ = 8 km/h
Thus, the average speed must you have for the second half of the trip to meet your goal is 8 km/h.
The value obtained (8 km/h) is not reasonable for the second half of the distance since the first half is 48km/h.

Explanation:
The figure that accompanies the question shows the wavelenghts of the photons emitted according to Balmer series transition , from energy levels (n) 3, 4, 5, and 6 to the energy level (n) 2, in hydrogen atoms.
These are the values shown in the figure
Transition wavelength of the photon emitted
nm
from n = 3 to n = 2 656 <------------- this is the value requested
from n = 4 to n = 2 486
from n = 5 to n= 2 434
from n = 6 to n = 2 410
The wavelength of a photon emitted from the n = 3 shell in hydrogen is the first data of the table, i.e 656 nm.
Using the conversion factor from nm to m that result is:
656 nm * 1 m / (10^9 nm) = 656 * 10 ^ - 9 m.
i believe it is c but i could be wrong. (i’m sorry if i am)
