Answer:
Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.
Explanation:
The concept that underlies the other would be :
effective nuclear charge zeff
It control Ip and electron affinity by determining attractive force between atom and the electron
it underlies atomic size because it draws the valence electron closer
hope this helps
Answer:
v = 51.36 m/s
Explanation:
given,
mass of the car = 805 Kg
circumference of the track = 4.25 Km
Force on the car in circular path, F = 3140 N
tangential speed of the car = ?
2 π r = 4250
r = 676.4 m
using formula
![F = \dfrac{mv^2}{r}](https://tex.z-dn.net/?f=F%20%3D%20%5Cdfrac%7Bmv%5E2%7D%7Br%7D)
![3140 = \dfrac{805\times v^2}{676.4}](https://tex.z-dn.net/?f=3140%20%3D%20%5Cdfrac%7B805%5Ctimes%20v%5E2%7D%7B676.4%7D)
v² = 2638.38
v = 51.36 m/s
hence, tangential speed of the car is equal to 51.36 m/s
