The time taken for one revolution of a rigid rotor to cross the nucleus is 6,240,000×10⁻¹⁵ sec .
Microwave rotational spectroscopy utilizes microwave radiation to quantify the energies of rotational advances for atoms in the gas stage. It achieves this through the communication of the electric dipole snapshot of the particles with the electromagnetic field of the astonishing microwave photon.
To test the unadulterated rotational advances for particles, researchers use microwave rotational spectroscopy. This spectroscopy uses photons in the microwave reach to cause changes between the quantum rotational energy levels of a gas particle.
We know that time taken to complete one revolution of a rigid rotor is
given by the formula J×(J+1)× B × h
where J is rotational quantum number,
B or I is rotational constant
and h or A is value of atomic mass of the nucleus.
So, on putting we get
=>t=2×(2+1)×5000×208
=>t=2×3×5000×208
=>t=6,240,000fm-sec or

The frequency heard is greater than frequency [tex]f_{0}[/tex].
This happens because of doppler's effect.
When the source and observer are moving relative to each other, the frequency observed by the observer (fa) is different from the actual frequency produced by the source (f0)Here, when the source of waves is moving towards the observer they will have an upward shift in frequency. As for the observers from whom the source is receding, there will be a downward shift in frequency.However, it should be noted that the effect does not occur as a result of the actual change in the frequency of the wave source. The main reason that we experience the Doppler effect is that as the wave source moves toward the observer, each new wave crest that is formed from the source is emitted from a location that is closer to the observer.Therefore, as the source moves closer and closer the waves will now take less time to reach the observer or the time between the arrivals of new wave crests is reduced.

Energy is the quantitative attribute that is transferred to a body or to a physical system. It is recognized in the execution of work as well as in the form of heat and light (from the Ancient Greek: v, enérgeia, "activity"). Energy can be transformed in form but cannot be created or destroyed, according to the rule of conservation of energy. The joule is the SI's (International System of Units) unit of measurement for energy.
A moving object's kinetic energy, a potential energy stored by an object (for instance because of its position in a field), the elastic energy contained in a solid object, chemical energy linked to chemical reactions, radiant energy carried by electromagnetic radiation, and internal energy contained within a thermodynamic system are examples of common forms of energy. Energy is continuously taken in and released by all living things.
Any item that has mass when it is motionless (referred to as rest mass) also has an equivalent amount of energy, known as rest energy. As a result, any additional energy (of any type) that the object acquires above that rest energy will increase the object's total mass as well as its total energy.

Mirrors and other reflecting surfaces can be used in the following way; used in kaleidoscopes, periscopes which are widely used in submarines, used in headlights to reflect parallel rays of light in a straight line etc.
What is a mirror?A mirror is a reflecting surface that reflects light almost totally and does not allow it to refract, producing a clear image. It produces either real or virtual images.
Types of MirrorsPlane Mirror - These are made by putting some reflective substance like silver nitrate onto a piece of glass. When we place an object in front of a plane mirror, an image is formed by reflection.
Concave - It is a mirror that is bent inside at its center. The law of reflection also holds for the concave mirror, but the angle of incidence is not equal to the angle of reflection. A concave mirror can produce a real or virtual image in front of it at its point of focus.
Convex - is also called a diverging mirror. The reflective surface of the convex mirror is slightly extended towards the source of light. A convex mirror can reflect all rays falling on it in the outward direction. It produces a virtual image. The size of the image produced by this kind of mirror is smaller than the actual object.
Uses of mirrorsA plane mirror is used in kaleidoscopes. Plane mirrors are also used in periscopes which are widely used in submarines.They are used in headlights to reflect parallel rays of light in a straight line. Convex mirrors are used as side mirrors in vehicles because they form erect images and cover wider views.

It has to be noted here that when we calculate the heat required during the same phase of the material requires the knowledge of change of temperature.

a positively-charged particle ( q) is at rest in the plane between two fixed bar magnets, as shown. the magnet on the left is three times as strong as the magnet on the right. which choice below best represents the resultant magnetic force exerted by the magnets on the charge?
The resultant force exerted by the magnets on the charge will be zero.
According to the Lorentz force equation, only moving charges experience magnetic forces. Therefore, a charge at rest experiences no force and does not move. Only moving charges can experience a magnetic force, so the force on a stationary charge is zero. The magnetic force is always perpendicular to the velocity of the charged particles, so the particles move in a circular motion. The positive charges above move vertically through the magnetic field and are deflected. The correct rule below predicts the direction in which positive charges are deflected. A similar left-hand rule predicts the deflection of negative charges.

suppose that events f and s are conditional independent events given d and ~d respectively with p(f|d)
The events f and s are conditional independent events given d and ~d respectively with p(D|F∩S) is 0.9529.
What is events?
An event in probability theory is a collection of experiment results to which a probability is ascribed. A single outcome might be a component of several events, and since various events in an experiment could have quite diverse groupings of outcomes, they are often not equally probable.
If F and S are conditionally independent given D and ~D, then
P(FSD)= P(D)P(F|D)P(S|D)
P(FS~D) = P(~D)P(F|~D)P(S|~D)
P(F|~D) = 1 - P(~F|~D)
P(S|~D) = 1 - P(~S|~D)
P(~D) = 1 - P(D)
P(D|FS) = P(FSD)/(P(FSD) + P(FS~D))
P(F|D) = P(S|D) = .9
P(~F|~D) = P(~S|~D) = .9
P(D = .2)
Then, P(FSD) = P(D)P(F|D)P(S|D) = .2*.9*.9 = .162
P(FS~D) = P(~D)P(F|~D)P(S|~D) = (1 - .2)(1 - .9)(1 - .9)= .008
P(D|FS) = P(FSD)/(P(FSD) + P(FS~D)) = .162/(.162+.008) = 162/170=81/85 = .9529

which factor leads to interference between waves? (2 points) a varying phase relationship between waves similar wave amplitudes unequal wavelengths radiation through different regions
The factor that leads to the interference of the waves is a varying phase relationship between waves.
What is interference of waves?The term interference of waves has to do with the way and manner in which two waves are able to combine. The waves may combine constructively or destructively.
If the waves combine constructively, this implies that the disturbance of the waves is increased but if the wave combines destructively then it means that degree of the disturbance of the waves is decreased.

what direct current will produce the same amount of thermal energy, in a particular resistor, as an alternating current that has a maximum value of 2.45 a? enter the magnitude of the direct current (in units of amps) in the box given below.
To provide the same amount of heating power as an alternating current with a peak value of 3.5 A, a given resistor has to have a direct current running through it of around 2.5 A.
In a series circuit, there is only one channel for electrons to take, hence the current is the same magnitude all the way around the circuit. A series circuit's total current is equal to the current flowing through all of its resistances.
The value of a sinusoidal voltage (or any other time-varying voltagerms )'s value is equal to the value of a dc voltage that generates an equivalent quantity of heat (power dissipation) as a result of the circuit current flowing through a resistance.
