When the only force acting on a falling object is air resistance, the object is said to be In free fall. TRUE
Answer:
Consider frames X and Y:
If X sees Y moving to his right then Y must see X moving to his right.
If this is not true then one can choose one frame over the other ( a favored frame and this is not allowed)
The truth is both of them are more reactive metal.
Answer:
The separation between the two lowest levels =
The values of n where the energy of molecule reaches 1/2 kT at 300K =
The separation at this level = 1.8 * J
Explanation:
Knowing the formula
En =
Mass of oxygen molecule
m (O2) = 32 amu *
So the energy diference between the two lowest levels:
E2 - E1 =
E2 - E1 =
Now we should find n where the energy of molecule reaches 1/2 kT
En = =
=
by the end is necessary to calculate the separation of the level
En - En-1 =
= 1.8 * J
