Answer:
u=speed, w=wavelenght, f=frequency
It's known that u=w*f => f=u/w
u=20m/s ==> f=20/0,5 => f=40 Hz
w=0,50m

B. Energy
A power company charges its customers for electricity based upon B. Energy.
<h3>
Explanation:</h3>
Kilo-watt Hours (kWh) is the unit that measures the electricity consumption of customers. Since Power is defined as the rate at which electrical energy is transferred by an electrical circuit per unit time,
![P = \frac{E}{t} \\E= P\times t](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7BE%7D%7Bt%7D%20%5C%5CE%3D%20P%5Ctimes%20t)
If energy is transmitted at a constant rate over a period of time, the total energy in kilowatt hours is the product of power in kilowatts(kW) and time in hours (h)
![1\ kWh = 3.6\times 10^6\ Joules](https://tex.z-dn.net/?f=1%5C%20kWh%20%3D%203.6%5Ctimes%2010%5E6%5C%20Joules)
ANSWER: d) 8
EXPLANATION: Two sets of two shared electrons (4 electrons total shared) = one set of a double covalent bond.
Therefore, 8 electrons total shared = two sets of double covalent bonds
