Which of the following sources of pollution would be the most difficult to track and regulate?
Answers
Lawn fertilizer runoff can be the most difficult to track and regulate since it may have spread in the soil and was washed away together with the water particles.
Pollution is an ecological disturbance and turmoil that ruins and endangers life either in land or sea, even air.
Three types of pollution exist:
Water pollution
Air pollution
Land pollution

f=4/2
f=2m/s
Hope this helps
Answer:
f = 0.5 Hz
v = 8 m/s
Explanation:
f = 1/T
f = 1/(2) = 0.5 Hz
v = λf
v = (2)(4) = 8 m/s

Answer:
E = h ν = h c / λ energy of photon
E = 6.62E-34 * 3.00E8 / 8.00E-7
E = 6.62 * 3.00 / 8.00 * e^-19 J
=2.5E-19 J

Frequency is the inverse of the time period. The frequency of the wave will be 0.02.
What is the frequency?
Frequency is defined as the number of cycles per second. The time to make one complete cycle is frequency.
Frequency = 1 / period
F= 1 / T
F=1/50 sec
F=0.02 Hz.
Hence, the frequency of the wave will be 0.02.
To learn more about frequency refer to:

in either direction between frequency and period.
(Frequency) times (Period) = 1 .
So Frequency = 1 / period
= 1 / (50 seconds)
= (1/50) per second
= 0.02 per second
= 0.02 Hertz

Answers
Answer;
-The energy needed to split an atom into separate protons, neutrons, and electrons
Explanation;
E = mc² The equation is derived directly from Einstein’s Special Theory of Relativity .
Each of the letters of E = mc2 stands for a particular physical quantity. Writing them out in full we get:
Energy = mass × the speed of light squared
In other words: E = energy (measured in joules, J), m = mass (measured in kilograms, kg), c = the speed of light (measured in metres per second, ms-1), but this needs to be squared.
Explanation :
Einstein's equation is given by :
..............(1)
m is the mass
c is the speed of light
The energy needed to split an atom into separate protons, neutrons, and electrons can be calculated by using equation (1).
The energy needed to split the nucleus into separate protons and neutrons is called nuclear binding energy.
The energy needed to remove an electron from an atom is called ionization energy.
The energy needed to add an electron to an atom is called electron affinity.
So, the correct option is (A).
