Answer:
Correct option : (c) period.
Explanation:
The time that is required for a vibrating object to complete one full cycle is called the time period. If f is the frequency of a wave, then the relation between the frequency and the time period is given by :
These are the characteristics of a wave. Some other characteristics are wavelength, amplitude, intensity etc. So, the correct option is (c) "period".
Coastal areas near water bodies like sea and oceans
Power = (voltage) x (current)
500 W = (120 v) x (current)
Current = (500 w) / (120 v) = 4-1/6 amperes .
Power and current are both rates.
Power is the rate of using energy ... joules per second.
Current is the rate of flowing charge ... coulombs per second.
Neither quantity depends on how long you keep it up.
They're both going on continuously while the vacuum is running.
<em>Speed of light in vacuum = 3.0 × 10⁸ m/s</em>
<em>Speed of light in water = 2.25 x 10⁸ m/s</em>
