Forced undamped vibrations

In mechanical engineering, vibration is expressed as the term that occurs due to an object's backward and forward movement about a point of equilibrium. Generally, there are three types of vibrations which are,

Question

What is Q? How did they get this answer break down simply for someone who does not understand?

5. A mechanical oscillator with a quality factor of 2 comprises a mass of 50 g attached
to a spring of stiffness 3250 N/m. When the mass is subject to an oscillating driving
force of magnitude 20 N, the resultant frequency of oscillation of the system is 50 Hz.
a). Calculate the value of the mechanical resistance, Rm, for the system.
b). What percentage of the maximum power is dissipated in the system when is it
driven to oscillate at 50 Hz?
c). State whether the system is underdamped, critically damped or overdamped when
the driving force is turned off and justify your answer.

I asked bartleby to solve this question earlier, it gave me AI answer which is completely different to what's shown in this answer. I don't know which one is correct now. I have attached screenshots of the AI answer. Can you clarify which is correct. Also I previously asked about pv diagram and you said ' the curve in the explanation is correct', did you mean in your explanation or the one I showed as an example? Please advice
Please Explain the answer,Thanks
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
