<span>when a wave causes vibration in a nearby object that matches the frequency of the wave, the phenomenon that occurs is called resonance.
It produces a sound of larger amplitude as a result of vigorous vibration of the body.

Number of Washers . . . Total Mass . . . Total Force . . . Ratio
1 ................................................0.6 kg ................5.9 N ........... 9.83 N/kg
2 ................................................1.2 kg ...............11.8 N ............ 9.83 N/kg
3 ................................................1.8 kg ..............17.6 N ............. 9.78 N/kg
4 ...............................................2.5 kg .............24.5 N ............. 9.80 N/kg
5 ...............................................3.2 kg ..............31.4 N ............. 9.81 N/kg
The ratios are listed in the table.
The ratio seems to be constant, and not depend on the number of washers or the total mass. It's always about 9.8 Newtons per kilogram of mass. There must be something special about that number.
The answer is option A "particle model." A particle model is the model that shows the movement and speed in substances. For example, in a solid the particles wouldn't have any movement, a liquid the particles are moving around slow, and a gas the particles are moving around quick.
Hope this helps.
A net force is the sum of all forces acting on an object. A net force is capable of accelerating a mass. For instance, if the wheels of a car push it forward with 5 Newtons<span> and drag is </span>3 Newtons<span> , the net force is </span>2 Newtons<span> , forward.</span>
