Option (A) is correct.
A noble gas is different from other elements because its highest electron energy level is completely filled.The examples of noble gases are helium, neon, Argon , krypton,Xenon , radon.
All the noble gases have completely filled outermost shell. for example, Helium has two electrons and both of them are present in first shell. Neon has 10 electrons, so its electronic configuration is 2,8.It has two electrons in the first shell and eight electrons in the second shell. Thus the outermost shell of both Helium and Neon is completely filled.
This property of having completely filled outermost shells makes noble gases different from the rest of the elements.These noble gases are very less reactive .
Answer:
Smaller velocity from the bigger one
Explanation:
When one calculates velocity they subtract the smaller velocity from the bigger one.

Answer:
560
Explanation:
Round your answer to two significant figures.
1) They are able to balance the torques due to gravity.
The torque is equal fo Force * lever arm.
The force downward is due to gravity, Force = mass*gravity.
Then the heavier student will produce a bigger force downgar and he/she shall shorten the lever arm of his/her side, by placing himself closer to the rotation axis, than the lighter student.
