Answer:
C
Explanation:
because when they are balanced they won't go anywhere only stay in the same spot

Given Information:
Inductance = L = 20 mH
Capacitance = C = 0.200 µF
Current = I = 0.100 A
Required Information:
Potential difference = V = ?
Answer:
Potential difference = 31.62 V
Explanation:
The energy stored in the electric field is given by
Ue = ½CV²
The energy stored in the magnetic field is given by
Um = ½LI²
From the principle of conservation of energy,
Ue = Um
½CV² = ½LI²
CV² = LI²
V² = LI²/C
V = √LI²/C
V = √(20x10⁻³*0.100²)/0.200x10⁻⁶
V = 31.62 V
Answer:
The sound travels differently in different medium according the density of the medium.
Explanation:
The sound travels faster in dense medium and can be heard by the vibration of the bone present in the ear. The ear plugs reduce the sound intensity in both medium water and on land (air).
In air the sound is not heard properly due to the earplugs that stops the as the vibration are not able to produce as sound is not able to reach to middle ear, but Navy researchers have discovered that sound under water is heard by the bone present behind the ear, vibrations mastoid.
