As you recognize , each electron features a unique set of quantum numbers that describes its exact location in an atom.
Specification :In your case, you're given two qunatum numbers, n, the principal quantum number, and ml , the *magnetic quantum number, and are sked to work out how many electrons can share these two quantum numbers in an atom.
The principal quantum number describes the energy state , or energy shell, on which the electron resides. Now, notice that the values the magnetic quantum number can take depend upon the value of l, the momentum quantum number.
Elaborating :For an electron that has n = 5, 4 are often l = {0 ; 1 ; 2; 3 ;4}
As you'll see, the magnetic quantum number can take values from − l all the high to l. If ml = 1, it follows that l could very easily be l = { 1 ;2 ;3; 4}
Finally, the spin quantum number, ms, which describes the electron's spin, can only take one among two values ms = {−1/2 ; + 1/2}
This means that you will have n = 5 ; l = 1 ; ml = 1 :ms = ± 1/2 n= 5 ; l = 2 ;ml=1 :ms= ± 1/2n = 5; l = 3 ;ml=1 :ms = ±1/2 n =5; l= 4 ;ml =1:ms=±1/2
Simply put, two electrons of opposite spins can share one orbital (given by ml=1) per sub shell (given by l).
Therefore, total of 9 electrons which will share those two quantum numbers.
What are the 4 quantum numbers?
In atoms, there are a complete of four quantum numbers: the principal quantum number (n), the orbital momentum quantum number (l), the magnetic quantum number (ml), and therefore the electron spin quantum number .

Projectile motion is the motion of an object thrown (projected) into the air. After the initial force that launches the object, it only experiences the force of gravity. The object is called a projectile, and its path is called its trajectory. As an object travels through the air, it encounters a frictional force that slows its motion called air resistance. Air resistance does significantly alter trajectory motion, but due to the difficulty in the calculation, it is ignored in introductory physics.

ground? How tall is the platform?
I
The time cannon ball to hit the ground is 9s and length of platform is 1,458 m.
Equation :To calculate time taken by cannon ball hit ground we use formula,
speed = distance / time
s = d / t
As given,
s is 18m/s
d is 162m
t = ?
Putting the values,
18m/s = 162m / t
t = 162m / 18m/s

The direction of the final velocity of the space shuttle flying north at 6,510 m/s, then accelerating at 28.4 m/s² for 60.0 seconds in the northeast direction I is approximately north 8.9° east.
How can the final direction of the velocity be calculated?The velocity of the space shuttle in the northeast direction after 60.0 seconds is therefore;
v = 28.4 × 60 = 1704
Which gives;
(vf)² = 6510²+1704²-2×6510×1704×cos(135)
(vf)² = 67383000.3975
vf = √(60971643.616) ≈ 7808.43
7808.43/sin(135) = 1704/sin(x)
x = arcsine (1704/(7808.43/sin(135)))

Planet building occurs through the process of accretion which involves the clumping of small particles into larger masses.
What is accretion?Its spatial period is known as the wavelength, which in physics is the distance that a periodic wave cycles across. It is a characteristic of both traveling waves and standing waves as well as other spatial wave patterns. It is the separation between two successively related wave points of the same phase, such as two close-by crests, troughs, or zero crossings. The inverse of the wavelength is known as the spatial frequency. It is commonly denoted by the Greek letter lambda, which is also known as the "wavelength." Also usually referred to as having a wavelength are the sinusoidal wave envelopes, modulated waves, and waves produced by the interference of several sinusoids. When a sinusoidal wave is thought to be moving at a constant speed, the relationship between wavelength and frequency is inverse.

Light consisting of small packets of energy called photons
Even though light mostly behaves like a wave, it can also be claimed that it is composed of tiny energy packets called photons. Despite being light and thin, photons are always energetic. The energy of a photon changes with wavelength; longer wavelengths have less energy than shorter ones. Red photons, for instance, have lower energy than blue ones.
Scientists believed that electromagnetic radiation was only made up of waves up until about 1900. Then, Max Planck and others found that some metals and other materials release electrons when exposed to light while studying the photoelectric effect.

Charges compare to the time-invariant generators of a balance bunch, and explicitly, to the generators that drive with the Hamiltonian. Charges are in many cases meant by the letter Q, thus the invariance of the charge compares to the evaporating commutator[Q,H]=0, where H is the Hamiltonian. Hence, accuses are related of moderated quantum numbers; these are the eigenvalues q of the generator Q. A charge is any generator of a persistent balance of the actual framework under study. At the point when an actual framework has a balance or the like, Noether's hypothesis infers the presence of a moderated current.

He2's molecular orbital energy-level diagram is shown in figure 3c. Both the 1s bonding and 1s antibonding orbitals must have two electrons for a total of four valence electrons.
What is antibonding molecular orbital?
An antibonding orbital is a form of molecular orbital that, according to the theory of chemical bonding, weakens the chemical link between two atoms while assisting in increasing the energy of the molecule in relation to the separated atoms. Such an orbital has one or more nodes in the area where the nuclei are bonded together. Outside of the bonding zone, where the orbital's electron density is concentrated, one nucleus is drawn away from the other, which tends to generate mutual repulsion between the two atoms. This is in contrast to a bonding molecular orbital, which is in charge of chemical bonds and has a lower energy than that of the individual atoms.

The ball will be in motion for about 2.44 seconds due to the free-fall.
What do you mean by free-fall?Free fall is any motion of a body in which gravity is the only force acting on it according to Newtonian mechanics. A body in free fall experiences no force according to general relativity, which reduces gravitation to space-time curvature. When something is in "free fall" in a technical sense, it may not necessarily be going down in the traditional sense of the word. Normally, an object traveling upwards might not be thought of as falling, but if it is solely being affected by gravity, it is said to be in free fall. As a result, the Moon is falling freely around the Earth, even if its fast orbital speed keeps it far from the planet's surface.
According to the question:
the ball is in motion for time, t = ?
initial velocity along y direction = 0
along y direction; h = 1/2gt²
from the above equation:
t = √2h/g
t = √(2×29.8)/9.8

The speed of a car traveling north on a major freeway and speed of a rocket launching into the space can both be measured using velocity.
The SI (international) units for the velocity are m/s (meters per second), but velocity may also be expressed in any units of distance per time. Other units include the miles per hour (mph), kilometers per hour (kph), and kilometers per second (km/s).
Velocity measures the motion starting in one place and heading toward another place.
