The energy of a photon of light is directly proportional to its frequency, a ahigh-energy photon has a  higher frequency and a short wavelength.

The length that a periodic wave repeats over in space is referred to as its wavelength in physics.

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's commonly represented by the Greek letter, or "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.

In order that the connections inside an outlet box remain accessible, the NEC requires that a surface extension from an outlet box cover be made using a flexible conduit only.

In the "surface extension" concept, the damper border dimensions are simply increased in relation to the air gap height. The extension coefficient is constant for continuum flow, but the rarefied gas causes the extension to vary on Kn. The elongation increases as Kn rises.

When a box's lid is constructed so that it is unlikely to come off or be removed if its locking mechanism becomes loose, one can create a surface extension from it. The wiring technique must be built for a length that is permitted and allows access to the inside of the box by removing the cover, and it must be set up such that any grounding continuous is independent of the connection between the box and cove.

By using uniform motion, the distance traveled by the swan is 51.43 meters.

We need to know about the uniform motion to solve this problem. The uniform motion is an object's motion under acceleration. It should follow the rule

vt = vo + a . t

vt² = vo² + 2a . s

s = vo . t + 1/2 . a . t²

where vt is final velocity, vo is initial velocity, a is acceleration, t is time and s is displacement.

From the question above, we know that

vo = 0 m/s

vt = 6 m/s

a = 0.35 m/s²

By using second equation, we can find the distance traveled by swan

vt² = vo² + 2a . s

6² = 0² + 2 . 0.35 . s

As you recognize , each electron features a unique set of quantum numbers that describes its exact location in an atom.

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.

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

Therefore, total of 9 electrons which will share those two quantum numbers.

6. Net force = 4 N

Explanation below

Hope this helps :)

Explanation:

To calculate net force, we must look at the direction it's pointing and the number of Newtons (N). If the arrow/arrows are pointing in the same direction, add the numbers, and the direction would be where the arrow is pointing (left,right,up,down). If the arrow/arrows are pointing in different directions, subtract the bigger and little number, and the direction would be where the bigger number is pointing (left,right,up,down).

It is only balanced when the net force is equal to zero. If the net force equals a number that's not zero like 1 and continuing on forever then it would be unbalanced.

Approximately, the student traveled 80.4672 m while looking at his cell phone.

While distance and displacement appear to signify the same thing, they actually have very different definitions and meanings. A scalar quantity known as distance measures "how much ground an object has traversed" while moving. An object's total change in position is referred to as displacement, a vector variable that measures "how far out of place an object is." Therefore it can be understood that distance measures the length between two objects without describing its direction. Hence distance is a scalar quantity(having no direction, it only has magnitude)

45 mph = 0.0201168 kmps

So distance covered in 1 sec is 0.0201168 km

The planets never travel in a straight line as they orbit the sun. according to newton's second law of motion, this must mean that the force is acting on the planets.

Newton's subsequent regulation is a quantitative depiction of the progressions that a power can create on the movement of a body. It expresses that the time pace of progress of the energy of a body is equivalent in both extent and heading to the power forced on it. The force of a body is equivalent to the result of its mass and its speed. Force, similar to speed, is a vector amount, having both greatness and bearing. A power applied to a body can change the size of the energy or its heading or both. Newton's subsequent regulation is one of the main in all of material science. For a body whose mass m is consistent, it tends to be written in the structure F = mama, where F (force) and a (speed increase) are both vector amounts. On the off chance that a body has a net power following up on it, it is advanced quickly as per the condition. On the other hand, on the off chance that a body isn't sped up, there is no net power following up on it.

The plane's displacement for the total trip is, -63.2°.

Velocity, v = x/t

Vx = 459 km/2.483 hr = 184.8 km/h

Vy = -909 km/2.483 hr = - 366 km/hr

Magnitude, v =sqrt(Vx^2 + Vy^2) = 410 km/hr

Direction, theta = arctan (-366/184.8) = - 63.2°

Double symmetrical illumination of the object, successively for each illumination direction, is used to measure in-plane displacement as the loading is gradually increased. The impact response of structures is significantly impacted by the in-plane displacements at the supports.

This is so that axial membrane forces along the beam's center line can be introduced by the development of geometrical modifications.
