The number of repetitions per second is called the frequency and is the inverse of the period. The period, T, is normally measured in seconds, and the frequency, ν, in Hertz. When the oscillations<span> (or vibrations) affect the material around them a </span>wave <span>is formed which transports energy away.</span>

Answer:
Sinkhole lakes in Florida typically occur in areas with a thin layer of soil overlying limestone, hi areas with impermeable clay soil, a lake might be perched (the lake level is maintained naturally above groundwater level, Fig. 3). The shapes of sinkhole lakes often show how they are formed....

Answer:
The current in any one of the resistors is 1 A.
Explanation:
It is given that, four 20 ohm resistors are connected in parallel. In parallel combination of resistors, the voltage across each and every resistor is same while the current divides. The equivalent resistance of all resistors is given by :


Current flowing in the entire circuit can be calculated using Ohm's law as :
Current, 

I = 4 A
Since, in parallel combination current divides. So, current flowing in all four resistor divides and is 1 A. Hence, this is the required solution.
