In cities, a phenomenon known as the "urban heat island effect" causes air temperatures to be warmer than in nearby suburban or rural areas and
The smoothness of the landscape and the local climate—not the materials of the concrete jungle—govern the urban heat island effect, a new study finds<span>

The magnitude of the electrostatic force between two identical ions that are separated by a distance of 8.3 × 10-10m is 192.9 ×

iragen [17]

Answer:

(a) 1.215 x 10^-13 J

(b) n = 7.6 x 10^5

Explanation:

distance, r = 8.3 x 10^-10 m

Force, F = 192.9 x 10^-9 N

Let the charge is q.

(a) According to the Coulomb's law

$F=\frac{Kq\times q}{r^{2}}$

$192.9\times10^{-9}=\frac{9\times10^{9}\times q\times q}{\left (8.3\times 10^{-10} \right )^{2}}$

q = 1.215 x 10^-13 C

(b) Let n number of electrons are missing.

$n = \frac{q}{e}=\frac{1.215\times10^{-13}}{1.6\times10^{-19}}$

n = 7.6 x 10^5

U can also add solar energy and hydro energy. Solar energy is by using the sun, while hydro is by using the force of water.
This is how hydro energy works:
its is usually built near a waterfall, OK so when the water falls of the cliff of the water fall , it creates a force which helps turn the generator and then it is carried into poles of electricity.
Hope this helps plus i gave u extra point Good luck :)
