Answer:

Quantum mechanics (QM; also known as quantum physics, quantum theory, the wave mechanical model, or matrix mechanics), INCLUDING quantum field theory, is a fundamental theory in physics describing the properties of nature on an atomic scale.

Classical physics, the description of physics that existed before the FORMULATION of the theory of relativity and of quantum mechanics, describes many aspects of nature at ordinary (macroscopic) scale. Quantum mechanics explains the aspects of nature at ordinary (macroscopic) scales but extends this description to the small (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale.[3] Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to DISCRETE values (quantization), objects have characteristics of both particles and waves (wave-particle duality), and there are limits to how accurately the value of a physical quantity can be predicted prior to its measurement, given a complete set of initial CONDITIONS (the uncertainty principle).

Quantum mechanics arose gradually, from theories to explain observations which could not be reconciled with classical physics, such as Max Planck's solution in 1900 to the black-body radiation problem, and the correspondence between energy and frequency in Albert Einstein's 1905 paper which explained the photoelectric effect. Early quantum theory was profoundly re-conceived in the mid-1920s by ERWIN Schrödinger, Werner Heisenberg, Max Born and others. The modern theory is formulated in various specially developed mathematical formalisms. In one of them, a mathematical function, the wave function, provides information about the probability amplitude of energy, momentum, and other physical properties of a particle.

In geometric optics, the paraxial approximation is a small-angle approximation USED in Gaussian optics and RAY tracing of light through an optical system (such as a lens). The paraxial approximation is used in Gaussian tracing. Ray TRANSFER matrix ANALYSIS is one method that uses the approximate.

ANSWER:

sinθ. Then the waveform shape produced by our SIMPLE SINGLE LOOP generator is commonly referred to as a Sine Wave as it is said to be sinusoidal in its shape. This type of waveform is called a sine wave because it is based on the TRIGONOMETRIC sine function used in mathematics, ( x(t) = Amax. sinθ ).

escape velocity is the minimum velocity with which a body must be projected vertically

upward so that it MAY just escape the SURFACE of

the earth. Expression for escape velocity let a body of MASS m be ESCAPED from the gravitational field of the earth.

Gauss's Law. Gauss's law states that the net flux of an electric field through a closed surface is PROPORTIONAL to the enclosed electric charge.The electric flux is defined as the electric field PASSING through a given area MULTIPLIED by the area of the surface in a plane PERPENDICULAR to the field

Answer:

Blood has three main functions: transport, protection and regulation. Blood transports the following SUBSTANCES: Gases, namely oxygen (O2) and carbon dioxide (CO2), between the LUNGS and rest of the body. Nutrients from the digestive tract and storage sites to the rest of the body

Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and WASTES mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood CLOTTING. White blood cells are part of the immune system and function in immune response.

Answer:

WE know that

CURRENT and resistance The current can be found from Ohm's Law, V = IR. The V is the battery voltage, so if R can be determined then the current can be calculated.

we have,

I = electric circuit having charge 200

R= 20 sec.

then according to the FORMULA

v=IR

Putting the VALUE,

V=200×20=4000

V=4000

ANSWER:

The Pack of Shampoo will FLOAT on water because its DENSITY is LOWER than that of Water

HOPE IT HELPS :

Since it is given that

m = 9.8 kg

We know that value of g at moon surface is

g = 1.625

Hence The weight of the body on the moon surface is :

W = mg

W = 9.8 x 1.625

W = 15 . 925 N

Hence the weight of the body at noon surface will be APPROXIMATELY EQUAL to 16 N

Answer:

Explanation:

[As we know, Pressure is DEFINED as the force exerted on a surface divided by the area over which that force ACTS.]

 P = F / A

∴ F = A * P

    = 2 * 10⁵N

=> [Work done can be defined as the product of the magnitude of the force acting and the displacement in the direction of the force.

Thus, Work done = force * distance MOVED by force

                            = 2 * 10⁵ * 1

                            = 2 * 10⁵ J.
