Answer:
Aufbau Principle
Explanation:
According to the The Aufbau Principle, the electrons will initialize the filling process of the orbital by filling the available orbitals with the lowest energy first prior to the filling the available orbitals of higher energies.
Since, in order to gain stability, each and every electron in an atom tends to minimize its energy, therefore, the energy of the atom as a whole is also minimum.
Answer:
The compound moves 6.5 cm in total.
Explanation:
Before solving this problem, let's first write down all lengths we know of from the question:
Starting point of sample = 1.0 cm from bottom of paper
Paper wet up to = 8.8 cm from bottom of paper
Ending point of the sample = 7.5 cm from bottom of paper
With these lengths stated, we can easily calculate the length which the compound moved through:
Length compound moved = Ending point - Starting point
Length compound moved = 7.5 - 1.0
Length compound moved = 6.5 cm
Thus, we can see that the compound moved 6.5 cm between the time the paper was put into, and taken out of the solvent.
Answer:
The amount of heat or moisture in the air
Explanation:
Or a switch
Its been some time so i might be wrong but i think the answer is 3 either or 2
Answer:
Explanation:
spring constant of spring = mg / x
= .4 x 9.8 / ( .95 - .65 )
=13.07 N / m
energy stored in spring = 1/2 k x²
= .5 x 13.07 x ( 1.2 - .65 )²
= 1.976 J
Let it goes x m beyond its equilibrium position
Total energy at initial point
= 1.976 + 1/2 m v²
= 1.976 + .5 x .4 x 1.6²
= 2.488 J
energy at final point
= mgh + 1/2 k x²
.4 x 9.8 x ( .55 + x ) + .5 x 13.07 x² = 2.488
6.535 x² + 2.156 + 3.92 x = 2.488
6.535 x² + 3.92 x - .332 = 0
x = .075 m
7.5 cm
