Producing nuclear energy is far more environmentally friendly than burning fossil fuels. That is the main benefit.
The main risk is radiation. If the nuclear waste is not properly disposed of, it can leak radiation into the environment. Fortunately, this is not an issue since there are ways to deal with it. There is also the risk of a disaster like the Chernobyl incident, however that was mostly due to faulty reactor construction. However, reactors today are built to avoid such issues.
<u>Answer:</u> The amount of time needed for 1 mole of electrons to pass through the lamp is 12.33 hrs.
<u>Explanation:</u>
We are given:
Moles of electron = 1 mole
According to mole concept:
1 mole of an atom contains 
number of particles.
We know that:
Charge on 1 electron = 
Charge on 1 mole of electrons = 
To calculate the time required, we use the equation:
where,
I = current passed = 2.17 A
q = total charge = 
t = time required = ?
Putting values in above equation, we get:
Converting this into hours, we use the conversion factor:
1 hr = 3600 seconds
So, 
Hence, the amount of time needed for 1 mole of electrons to pass through the lamp is 12.33 hrs.
Answer:
<em>7.2 N</em>
Explanation:
length of wire L = 240 m
current I = 500 A
field strength B = 3 x 10^-5 T
magnetic force on a current carrying conductor F is given as
F = BILsin∅
The wires are perpendicular with field therefore sin∅ = sin 90° = 1
therefore,
F = BIL = 3 x 10^-5 X 500 X 240 = 3.6 N
<em>If the wire exists between this two transmission lines, then total magnetic force on the wire = 2 x 3.6 = 7.2 N</em>
