Answer:
4f E₄ = 0.85 eV, L₄ = 4.22 10⁻³⁴
,
5d E₅ = 0.544 eV
, L5 = 5.28 10⁻³⁴
Explanation:
Let's use the Bohr model, stable the energy of the hydrogen atom
E = -13.606 / n2
where Eo = 13.606 eV is the energy of the ground states.
a) the energy of each atom
level 4f
In this nomenclature enumeration is the number n
E = -13606 / 42
E₄ = 0.85 eV
level 5d
E₅ = -13.606 / 5 2
E₅ = 0.544 eV
b) The angular momentum is given in Boh's model
L = n h / 2pi
let's calculate
level 4f L₄ = 4 6.63 10⁻³⁴-34 / 2 pi
L₄ = 4.22 10⁻³⁴
level 4d
L5 = 5 6.63 10-⁻³⁴ / 2pi
L5 = 5.28 10⁻³⁴
c) The hydrogen atom in state n = 5 has lower energy than the other state
d) Atom 1 has less angular momentum than atom 2
Complete Question
Alberta is going to have dinner at her grandmother's house, but she is running a bit behind schedule. As she gets onto the highway, she knows that she must exit the highway within 55 min if she is not going to arrive late. Her exit is 43 mi away. How much time would it take at the posted 60 mph speed?
Answer:
The time it would take at the given speed is 
Explanation:
From the question we are told that
The time taken to exist the highway is 
The distance to the exist is 
Alberta speed is 
The time it would take travelling at the given speed is mathematically represented as
substituting values
Converting to minutes
1 hour = 60 minutes
So 0.71667 hours = x minutes
Therefore
Answer: b. The flow of air is neither toward the warm air mass nor toward the cold air mass.
A stationary front forms between two air masses. A stationary front results when the warm front or cold front air stops moving. This occurs due to the fact that warm front and cold front air masses being opposite to each other but neither of them are able to repel the other. This affects the climatic conditions of the region. The weather is often cloudy along a stationary front and also supported with fall of rain and snow especially if the air in the front is cold with low atmospheric pressure.
<em>Therefore, along a stationary front the flow of air is neither toward the warm air mass nor toward the cold air mass.

Here's the formula for mechanical advantage.
It's very important, and you should memorize it:
Mechanical Advantage = (output force) divided by (input force) .
#1). Force that moves the object = output force = 550N
Force that it takes = input force = 200N
Use the formula:
(output force) divided by (input force) = 550N/200N = 2.75 .
#2).
#3).
#4).
#5).
#6).
#7).
#8).
#9).
#10).
All of the rest of the problems on the page tell you the input force
and the output force. They can be solved by using the same formula
to calculate the mechanical advantage, just like I did in #1).
I disagree with the first sentence of #11. But by the time you get there,
you'll be an expert in mechanical advantage, so you can investigate and
decide who's correct ... the sheet or me.
