here we have to calculate the net positive charge present on he surface of the conducting sphere.
as the sphere is a conducting one the,the charge will be stored on its surface.
though the charge is present at the surface,still it will behave just like the total charge is concentrated at the centre of the sphere.
the electric field at outside of the sphere is E=
as E=
so V=
here V=27 volt,radius of sphere is 0.800 m and the point at which the potential is considered is at 1.20 m from th centre of the sphere.hence the point is at the outside of the sphere .
hence we have 27=
q=27× coulomb
=3.6× coulomb [ans]
The adds pressure to the tire which would cause it to burst
Answer: D
Explanation: The chemical bonds in the food store energy that is released when we eat it.
If only I was smart then I could help you :/ no but like for real im madddd dumb sorry :(
Part a
Answer:
For the arrangement considered in part a, all the atoms are aligned side by side along the side of the square surface.
Along one side of the square, the number of atoms that could fit
This is along one side. On the entire surface:
Number of atoms
Part b
Answer:
consider the attached figure below:
The next layer of atoms are filled in the depressions of the first layer. The vertical distance between the two atoms would change. Consider an equilateral triangle drawn by joining the centers of the three atoms.
The atoms along the horizontal side would be aligned side by side; same as above
The number of atoms along vertical side would vary. vertical distance between two atoms can be calculate using equilateral triangle as shown below.
an equilateral triangle has all the angles
Let the vertical distance be y.
Then,
where r is the radius of each atom.
The number of atoms along the vertical side
Total number of atoms in this kind of arrangement
