What is K in elastic potential energy formula?
k in elastic potential energy is the spring constant. It is also known as a proportionality constant that describes the relationship between the strain in the spring and the force that causes it.
Elastic potential energy is the potential energy stored by stretching or compressing an elastic object by an external force such as the stretching of a spring. It is equal to the work done to stretch the spring which depends on the spring constant k and the distance stretched.
The spring constant is the measure of stiffness of the spring. The spring constant tells us, how many newtons of force it takes to stretch the spring by one meter.
The spring constant depends on the stiffness of the spring material, the thickness of the wire from which the spring is wound, the diameter of the turns of the coil, the number of turns per unit length and the overall length of the spring.

What is the wavelength of a radio wave with frequency 8.95 x107 Hz?
The wavelength of a radio wave is 3.352m .
Planck himself originally imagined it to be the constant of proportionality.
Like every other wave, electromagnetic radiation consists of a frequency and a wavelength, and the product of these is continually identical to c, the speed of light.
Electromagnetic waves are all round us, and in addition to visible radiation, different wavelengths are generally known as radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays.
All of these varieties of electromagnetic radiation have a similar basic type as defined by using Maxwell’s equations; however, their energies range with frequency (i.e., a higher frequency means that better electricity).
As he knew from Maxwell, the energy of a wave is proportional to its frequency.
So E ∝ v
Inserting the constant of proportionality gives: E=hv
Using this equation, we can calculate the energy of only single wave particles: photons, electrons, protons, neutrinos, muons, etc.
The Frequency of radio wave is 8.95 x 10⁷Hz.

The average velocity of the pirates is 1.44 miles/hr.
A vector quantity is an average velocity. The change in position or displacement (x) divided by the time intervals (t) in which the displacement happens yields the average velocity. Depending on the sign of the displacement, the average velocity can be positive or negative. Meters per second (m/s or ms-1) is the SI measure of average velocity.
total time = t₁ + 1 + t₂
T = 1 + 1 + 3
T = 5hr
Displacement = AC = √(4² + 6²)
S = √16+36
S = √52
Average velocity = Displacement/ Time

which phenomenon that goes unexplained by lewis structures is solved by applying molecular orbital theory?
In terms of combinations of the atomic wave functions, the Molecular Orbital (MO) Theory defines how electrons behave in molecules. All of the atoms in the molecule may be covered by the resulting molecular orbitals.
A molecule is stabilized by the presence of electrons in bonding molecular orbitals, which are created by in-phase combinations of atomic wave functions. A molecule becomes less stable when electrons are located in antibonding molecular orbitals, which are produced by out-of-phase combinations of atomic wave functions. MOs are atomic orbitals that are situated along an internuclear axis. S orbitals or p orbitals orientated end to end can be used to create them.The electron density of orbitals, which are produced from p orbitals positioned side by side, is on the opposite side of the internuclear axis. By using the valence electrons of the atoms in conjunction with molecular orbital theory, we can describe the electronic structure of diatomic molecules.Although there are two unpaired electrons in the molecule's molecular orbital description, the electrons in the Lewis structure are all paired. As a result, by examining how a magnetic field affects oxygen, we can test the predictions of these theories.

It is the property because of which a body keeps up with its internal compass. eg When we travel by a motorcar and in the event that it makes a sharp turn at a fast, we will quite often get tossed aside.

Noise cancelling headphones are a kind of headphones which decrease the amount of background noise that get into your ears when you wear them. On what physical phenomena do these headphones depend on?
The theory of destructive interference underlies the operation of noise-cancelling headphones.
The process of using passive and active noise control techniques to reduce undesired background and ambient noises is known as noise cancellation.
Active noise cancelling (ANC) adopts a different strategy from passive noise cancellation by "neutralising" incoming sound waves from your surroundings. Passive noise cancellation reduces ambient noise by erecting a "physical shield" to mask sound.
Small microphones built into ANC headphones send out sound waves that interfere with incoming sound waves from the environment, cancelling each other out. It's comparable to adding +3 and -3, where the result is zero (silence).
Both inside and outside the headphones' walls are picked up by the microphones.

How does mass affect the amount of kinetic energy in a moving object? Explain how you know by stating your claim, the evidence for your claim, and your reason why this evidence supports your claim.
A moving object's kinetic energy is inversely correlated with its mass and inversely correlated with the square of its speed.
What is the impact of mass on kinetic energy?If all other variables are maintained constant, mass and kinetic energy have a positive relationship, which indicates that as mass grows, kinetic energy increases. Accordingly, an object with the same mass and speed as another object will have twice the kinetic energy, and another object with the same mass and speed as another object will have four times the initial kinetic energy.
It is more difficult to move and stop heavier objects (i.e., items with more mass). Greater mass, or heavier items, resist change more than lighter ones do.

The nurse is applying a rightward horizontal force on a bed which has a mass of 152 kg.
If the mass of the bed is 152 kg then the force of gravity on the bed is,
W = Mg
M is mass of bed and g is gravitational acceleration.
Putting values,
W = 152×9.8
W = 1489.6 N.
The normal force is always perpendicular to the surface of the bed so, the normal force on the bed will be equal to the weight of the bed which is 1489.6N.
So, the normal force on the bed is 1489.6N.

Which type of energy is associated with the position and motion of an object *?
Mechanical energy is associated with the position and motion of an object. Potential energy is associated with the position of an object, and kinetic energy is associated with the motion of an object.
Potential energy and kinetic energy are two kinds of mechanical energy. Potential energy is due to the position, shape, or height of an object. For example, the energy stored in a coiled spring, the energy stored in a water tank at height, and energy in charges due to their relative positions to each other.
The kinetic energy in an object is due to its motion—for example, energy in flowing water and blowing wind.
At a point of time, the total mechanical energy in an object remains constant. Potential and kinetic energy transforms into one another and thus keep total mechanical energy in an object constant.
