Explanation:
Atoms of some elements shows no desire to form bonds or combine with themselves or other kinds of atom because their outer energy levels are completely filled.
Helium has a duplet configuration whereas other atoms of the noble gases have an octet configuration.
- The driving force for many interatomic bonding is the tendency to have completely filled outer energy levels like the noble gases.
- The various interatomic bonds form in a bid of the atom to be isoelectronic in the outer energy level with the noble gases.
- This leads to loss, gain or sharing of electrons between atoms.

Answer:
Nitrogen and oxygen
Explanation:
Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions.
Answer:
Conduction occurs when two objects at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. ... It is caused by the increased activity or speed of molecules in a substance, which in turn causes temperature to rise accordingly. This process continues until heat energy from the warmer object spreads throughout the cooler object.
Explanation:
Answer:
The total resistance of the circuit is 35 ohms and the total current through the circuit is 0.34 A.
Explanation:
Given that,
The total voltage of the 4 batteries = 12 V
Values of resistances are 25 ohm and 10 ohm.
The total resistance in the series combination is given by :
![R_T=R_1+R_2\\\\R_T=25+10\\\\R_T=35\ \Omega](https://tex.z-dn.net/?f=R_T%3DR_1%2BR_2%5C%5C%5C%5CR_T%3D25%2B10%5C%5C%5C%5CR_T%3D35%5C%20%5COmega)
Let I be the total current through the circuit. It can be solved using Ohm's law as follows :
![V=IR_T\\\\I=\dfrac{V}{R_T}\\\\I=\dfrac{12}{35}\\\\I=0.34\ A](https://tex.z-dn.net/?f=V%3DIR_T%5C%5C%5C%5CI%3D%5Cdfrac%7BV%7D%7BR_T%7D%5C%5C%5C%5CI%3D%5Cdfrac%7B12%7D%7B35%7D%5C%5C%5C%5CI%3D0.34%5C%20A)
Hence, this is the required solution.
<span>Angular distance moved = 220 rad = {35(2π) ≈ 220 rad}
Max angular speed = 18 rad/s
Final angular speed = 0 rad/s
Avg angular speed = 9 rad/s {assuming a CONSTANT de-celeration of wheel}
Time to stop = 220/9 = 24.4 s ANS</span>
