Answer:
a) Fₓ = 23.5 N
b) Net force = Fₓ
Explanation:
An image of the question as described is attached to this solution.
From the image attached, the forces acting on the box include the weight of the box, the normal reaction of the surface on the box, the applied force on the box and the Frictional force opposing the motion of the box (which is negligible and equal to 0)
a) From the diagram, the horizontal component of the force is
Fₓ = 25 cos 20° = 23.49 N = 25 N
b) Again, from the diagram attached, doing a force balance on the box, in the horizontal direction, we obtain
Net force = Fₓ - Frictional force
But frictional force is 0 N
Net force = Fₓ

Check Explanation
Explanation:
This is a question that is as a result of an experimental procedure.
The Phet simulation is put on the settings given in the question;
- select Oscillate
- Select No End
- Use the parameters in parentheses by sliding the bars for Amplitude (1.00 cm), Frequency (1.40 Hz)
- Damping (none)
- Tension (highest)
I'll attach an interface of the Phet simulation to this solution.
Once all of these settings have been fixed, the simulation gives a wave pattern whose wavelength can be read from the ruler attached to the background of the simulation.
The wavelength is the distance from crest to crest or from trough to trough.
From the simulation example I have attached, the distance from crest to crest is from the green indicator on one crest to the green indicator on the next crest, that is about 5 to 5.1 cm
The velocity of a wave, v, is related to the frequency, f, and wavelength, λ of the wave through
v = fλ
For the photon, the velocity of the wave is the speed of light,
v = c = (3.00 × 10⁸) m/s
The wavelength computed from the simulation = λ = 5.1 cm = 0.051 m
c = fλ
frequency = (c/λ) = (3.00 × 10⁸) ÷ 0.051 = (5.88 × 10⁹) Hz
So, this step can be used to obtaim rhe required frequency of the photon, just follow these steps and use the calculation method too. You should be able to obtain the frequency of the photon in your experiment.
Hope this Helps!!!
