Unless if all forces cancel each other out , the object will no longer be in equilibrium
Answer:
1. The period is 1.74 s.
2. The frequency is 0.57 Hz
Explanation:
1. Determination of the the period.
Spring constant (K) = 30 N/m
Mass (m) = 2.3 Kg
Pi (π) = 3.14
Period (T) =?
The period of the vibration can be obtained as follow:
T = 2π√(m/K)
T = 2 × 3.14 × √(2.3 / 30)
T = 6.28 × √(2.3 / 30)
T = 1.74 s
Thus, the period of the vibration is 1.74 s.
2. Determination of the frequency.
Period (T) = 1.74 s
Frequency (f) =?
The frequency of the vibration can be obtained as follow:
f = 1/T
f = 1/1.74
f = 0.57 Hz
Thus, the frequency of the vibration is 0.57 Hz

Well, there aren't actually ANY that apply, because you haven't listed any. But I've lived a long time, and I remember hearing about electromagnetic waves and things that use them, so I can list a FEW of them for you:
-- radios
-- TVs
-- garage-door openers
-- TV remotes
-- cell phones
-- smart phones
-- GPS
-- walkie-talkies
-- car headlights
-- lava lamps
-- toasters
-- LEDs
-- light bulbs
-- fluorescent light tubes
-- police radios
-- Doppler weather radars
-- CB radios
-- ham radios
-- neon signs
-- eyeglasses
-- microscopes
-- telescopes
-- gas stoves
-- electric stoves
-- wood stoves
-- microwave ovens
-- tanning beds
-- cameras
-- lasers
-- CD recorders and players
-- DVD recorders and players
-- Bluray recorders and players
-- movie cameras
-- movie projectors
-- reading lamps
-- candles
-- whale-oil lamps
-- kerosene lanterns
-- flashlights
-- campfires
-- coffee percolators
-- heat lamps
-- cordless phones
These are just the ones I can think of right now off the top of my head. There are a lot of others.
A car slowing as it reaches a traffic light, because it is the only option with acceleration/ deceleration.
And forces require the mass of the object AND the acceleration.
