Explanation:
The equator has no continental borders.
Answer:
Explanation:
The volume of a sphere is:
V = 4/3 * π * a^3
The volume charge density would then be:
p = Q/V
p = 3*Q/(4 * π * a^3)
If the charge density depends on the radius:
p = f(r) = k * r
I integrate the charge density in spherical coordinates. The charge density integrated in the whole volume is equal to total charge.





Since p = k*r
Q = p*π^2*r^3 / 2
Then:
p(r) = 2*Q / (π^2*r^3)
Answer:
Adding heat makes the particles move faster so the particles have more kinetic energy when more thermal energy is added

Answer:
a force
Explanation:
a force causes a certain object to move and make a displacement.
