Answer:
D. The friction force increases by 9600 N.
Explanation:
Frictional force is directly proportional to kinetic coefient of friction.
It has to lose electrons to become positively charged, so it can attract a negatively charged oxygen ion.

Explanation:
Answer:
It has only 1 electron in its valence shell and if that electron is removed it will acquire noble gas configuration
Explanation:
Sodium forms an ion of charge +1 as in its ionic state it has inert gas configuration
It forms an ion of charge +1 when the valence shell electron is removed to gain the noble gas configuration and the electrons can be removed mostly from its valence shell because inner shell electrons will be tightly bounded to the nucleus of the atom and it requires high energy to remove the electron present in the inner shell when compared to the valence shell (outermost shell)
Answer:
A 1 kg block sliding to the right on a level, frictionless surface with a speed
of 2 m/s collides and sticks to a second 1 kg block sliding to the left. After
the collision, the blocks are motionless. What was the speed of the second
1 kg block before the collision?
