Answer:
Explanation:
Why are students in Hawaii required to learn the history of debate surrounding the writing of the first 10 amendments to the constitution? They were not a member of the United States at the time?
The reason they have to learn anything they can about the constitution is because they are governed by it (just as you are).
The reason you have to learn about the Earth's Systems is because currently there is a huge debate about global warming. The problem is that we are not sure what the solution might be and we've already spent billions on reducing our effect on the environment. Billions means your tax dollars (many) or that of your parents. Many scientists are not sure we should be doing anything.
You will enter the work force one day and if you get a good job, you will be taxed. You should never be unaware of what your tax dollars are spent on.
Urine is a liquid by-product of metabolism in humans and in many other animals. Urine flows from the kidneys through the ureters to the urinary bladder. Urination results in urine being excreted from the body through the urethra.

Answer:
f = 735 Hz
Explanation:
given,
Person distance from speakers
r₁ = 4.1 m r₂ = 4.8 m
Path difference
d = r₂ - r₁ = 4.8 - 4.1 = 0.7 m
For destructive interference
where, n = 1, 3,5..
we know, λ = v/f
v is the speed of the sound = 343 m/s
f is the frequency
for n = 1
f = 245 Hz
for n = 3
f = 735 Hz
Hence,the second lowest frequency of the destructive interference is 735 Hz.
The charges are the same in absolute value, so the change of potential energy is the same. That means that the change in kinetic energy is also the same. Then:
1 = Ke/Kp = m_e *v_e^2 / m_p * v_p^2, or
v_e/v_p = sqrt( m_p/m_e),
So the speed of the electron will be sqrt( m_p/m_e) times greater than the speed of the proton
