<span>B is the right answer. Global warming is caused by carbon dioxide and water vapor which are not air pollution. Indeed most air pollution counteracts global warming by reflecting sunlight.</span>
According to Coulomb’s Law, the force will quadruple.
However…
Let’s assume, for the sake of argument, that both proton and electron behave entirely like particles.
The trajectory of the electron will stretch, and its distance from the nucleus will oscilate until is estabilizes again at the original value.
Vectors have both size and direction.
Vectors are indicated with arrows.
Vectors can have positive or negative values.
<h3><u>Answer;</u></h3>
= 4.19 Joules
<h3><u>Solution;</u></h3>
Energy stored in capacitor = U = 8.38 J
U =(1/2)CV^2
C =(eo)A/d
C*d=(eo)A=constant
C2d2=C1d1
C2=C1d1/d2
Initial separation between the plates =d1= 2.30mm .
Final separation = d2 = 1.15 mm
But; Energy=U =(1/2)q^2/C
U2C2 = U1C1
U2 =U1C1 /C2
U2 =U1d2/d1
Final energy = Uf = initial energy × d2/d1
= 8.38 ×1.15/2.30
= 4.19 Joules
Thus; The final energy = 4.19 Joules
Answer:
Im not sure if you mean miles per hour or meters per hour but if it is miles it is 4.97 miles per hour and if it is meters then it is 8000 meters per hour
