'Frequency' is a word that often confuses some people ... for no good reason.
It just means "frequent-ness" or "often-ness" ... how often something happens.
The SI unit of frequency is the Hertz (Hz). Hz means 'per second'.
So " 13 Hz " means 13 per second.
Here are examples of frequency:
-- 780 kilohertz (on your AM radio dial)
-- 98.7 Megahertz (on your FM dial)
-- 5.8 Gigahertz
-- twice a day
-- three per week
-- every 6 months

Answer:
Option(b) is the correct answer to the given question .
Explanation:
The taste of the acids are sour due to H- ions where the taste of bases are bitter due to the OH-ions. The HP value of the acids are less than 7 where as the HP value of bases are greater than 7 .
The POH value of the acids are greater than the 7 and POH value of acids are less than the 7 . HP and the POH scale are used to find the difference between acid and the base.
- All the other options are not correct for the acids that's why these are incorrect option .
Therefore Option(b) is the correct answer .
Answer:
The pressure of water progressively increases as the depth of the water increases. The pressure increases as the depth of a point in a liquid increases. The walls of the vessel in which liquids are held are likewise subjected to pressure. The sideways pressure exerted by liquids increases as the liquid depth increases.
Answer:
Homogenity means identical and even distribution of matter in every location and isotropic means distribution that is the same in every direction. The population is inhomogeneous because it consist of different species and has an uneven distribution, however it is isotropic because the distribution is the same in every direction. if you were to cut the circular section from the center to the end, in every direction you may look it will always be the same.
