We have that for the Question "Write an expression for the <em>magnitude </em>of charge moved, Q, in terms of N and the fundamental charge e" it can be said its equation is

From the question we are told
Write an expression for the <em>magnitude </em>of charge moved, Q, in terms of N and the fundamental charge e
<h3>An E
xpression for the <em>magnitude </em>of charge moved</h3>
Generally the equation for the <em>magnitude </em>of charge moved, Q is mathematically given as

Therefore

We use v=IR and assuming the resistance doesn’t change we can also say that the voltage and current (I) are directly proportional which means the voltage also decreases by 1/2
Answer:
Precipitation amounts
Explanation:
Meteorologists are scientists whose job is to predict different weather weather conditions. They study the atmosphere of the earth thoroughly so as to make a clear and concise weather forecast.
Meteorologists makes it possible for people to get information on possible rainfall or sunshine, it also enable people to know about a possible hurricance occurrence.
Meteorologists make use of a variety of tools to predict the weather, they include: wind vanes, barometers, anemometers, rain gauges, thermometer, hydrometer, Campbell Stokes Recorder,Transmissometer.
Answer:
The transmitted intensity through all polarizers is 
Explanation:
According to Malu's law the intensity of a polarized light having an initial intensity
is mathematically represented as

Now considering the polarizer(The polarizing disk) the equation above becomes

Where n is the number of polarizers
Substituting
for the initial intensity 3 for the n and 20° for the angle of rotation
