Answer:
B. Two waves have displaced in opposite directions
Explanation:
Interference occurs when two waves meet at a point in space. When this occurs, two extreme conditions can occur:
- if the two waves are in phase (=displacement in the same direction), the amplitude of the resultant wave is equal to the sum of the amplitudes of the two waves:
A = A1 + A2
and this condition is called constructive interference
- if the two waves are in anti-phase (=displacement in opposite directions), the amplitude of the resultant wave is equal to the difference of the amplitudes of the two waves:
A = |A1 - A2|
and this condition is called destructive interference. Note that if A1=A2, the amplitude of the resultant wave is zero.
Answer:
a) CI^- ⇒ CI2 + 2e^-
b) 4.2 * 10^9 amperes
c) 1.4 * 10^10 watts
Explanation:
Given data:
Annual production of C12 = 45 millions tons per year
Typical plant operational percentage = 90%
Operating voltage of a cell = 3.4 v
A) Half-cell reaction for oxidation chloride to form chlorine
CI^- ⇒ CI2 + 2e^-
B) Calculate the total current worldwide needed to generate the global supply of CI 2
Total current = 
= 
= 4.2 * 10^9 amperes
Q = charge , t = time
C ) Calculate electrical power need to produce global supply of chlorine using electrolysis
P = V*I
= 3.4 * 4.2 * 10^9
= 1.4 * 10^10 watts
Atoms from two different elements may have the same number of neutrons, but never the same number of protons. The number of protons is unique to the element and represents the atomic number.
Explanation:
If force or distance is increased, then amount of workdone will also increase.
These magnetic reversals, in which the direction of the field is flipped, are believed to occur when small, complex fluctuations of magnetic fields in the Earth's outer liquid core interfere with the Earth's main dipolar magnetic field to the point where they overwhelm it, causing it to reverse.
