The particles that move in orbits of the same radius have the same momentum.
<h3>
Orbital angular momentum:</h3>
A point particle's three-dimensional angular momentum is traditionally represented by the pseudovector r p, which is the cross product of the particle's position vector r (relative to some origin) and momentum vector, which in Newtonian physics is denoted by p = mv.
L = mr
= mr²w is the particle's orbital angular momentum in units of magnitude. The part of the particle's velocity that is here perpendicular to the axis of rotation is designated as 
The right-hand rule indicates the direction of the angular momentum. In isolated systems, the angular momentum is conserved.

Answer:
(h₁-h₂) = 2.30 10² m
Explanation:
The pressure depends on the height with the formula
P = P_atm + rho g h
Let's apply this expression for the building
P₁ = P_atm + rho_air g h₁
P₂ = P_atm + rho_air g h₂
Subtract
P₁ - P₂ = roh_air g (h₁ –h₂)
The measured pressure is in mm Hg to take this unit to units of pressure must be multiplied by the density of mercury and the acceleration of gravity
P₁- P₂ = rho_Hg g (h₁-h₂) _Hg
rho_Hg g (h₁-h₂) _Hg = roh_air g (h₁ –h₂)
(h₁ –h₂) = rho_Hg / rho_air (h₁-h₂) _ Hg
Let's calculate
(h₁-h₂) = 13600 / 1.18 (695-675)
(h₁-h₂) = 2.30 10⁵ mm
Let's reduce to meter
(h₁-h₂) = 2.30 10⁵ mm (1 m / 10³ mm)
(h₁-h₂) = 2.30 10² m
The kinetic energy of the ejected electrons will be 2782.5 ×10⁻²² eV.
<h3>What is threshold frequency?</h3>
The threshold frequency of incoming radiation is the lowest frequency at which photoelectric emission or electron emission is impossible.
The threshold frequency is the light frequency that causes an electron to dislodge and emit from the metal's surface.
From the photoelectric effect, the equation obtained as;
Hence,the kinetic energy of the ejected electrons will be 2782.5 ×10⁻²² eV.

Answer: A-B-C-E-G-K-H-I
Explanation:
Ok, we start at A.
16 pints = x gallons.
We know that:
1 pint = 0.125 al
then:
16pint = 16*(0.125gal) = 2 gal.
The second letter is B.
Now we have:
12,320 yd = X mi
And we know that:
1 mi = 1760 yd.
Then 12,320yd = (12,320/1760) mi = 7mi
the letter is C.
Now we have:
432 cups = X gals
and:
1 cup = 0.0625 gal
then 432 cups = 432*(0.0625 gal) = 27 gal.
The next letter is E.
Now we have:
1/4 ton = X pounds.
And 1 ton = 2000 pounds
then 1/4 ton = (1/4)*2000 pounds = 500 pounds
The next letter is G.
Now we have:
3.5 gal = X ounces.
and we know that:
1 gal = 128 oz
Then:
3.5 gal = 3.5*(128oz) = 448oz
The next letter is K.
Now we have:
1/2 day = x minutes.
and we know that:
1 day = 24*60 min = 1440 min
then 1/2 day = (1/2)*1440 min = 720 min.
The next letter is H.
Now we have:
360 in = x yd
And we know that:
1yd = 36 inches.
then 360 in = (360/36) = 10 yd.
The next letter is I
Now we have:
56 cups = x quarts.
and we know that;
1cup = 0.25 quart
then: 56 cups = 56*0.25 quart = 14
So here this ends.
Then the code is:
A-B-C-E-G-K-H-I
