You should commit this fact to memory. The value of the Boltzmann Constant is 1.381 x 10-23 J/K. Option B is therefore accurate.

Jacques Charles discovered Charles’s law, also known as the law of volumes, in 1787. It asserts that, under the assumption of a closed system, the volume of an ideal gas at constant pressure is directly proportional to its absolute temperature for a given mass.

Because alpha particles contain two protons and two neutrons, they have the highest mass. They weigh 4 mp.

B. An electron, or me, has the same mass as a beta particle.

Since gamma rays have no mass,

Their mass is insignificant.

Q = I x t

Consequently, t = Q / I

250 seconds (t = 5000 / 20)

The static area surrounding a magnet where the magnetic force is present is called magnetic flux. The quantity of magnetic field lines that flow through a specific surface area is known as magnetic flux. An electromotive force (EMF) is induced in a conductor by a fluctuating magnetic field, as per Faraday’s Law of Electromagnetic Induction. In contrast to the initial change in magnetic flux, this EMF creates a current that creates a magnetic field. Lenz’s Law is the name given to this phenomenon. Because any change in the magnetic field would cause an EMF that would create a current that opposes the change in flux, a magnetic field cannot change in flux. Therefore, the only right response is option D.

P/V=I I=200/220 P=VI

I= 0.9 Amp.

In electrostatics equations, the Coulomb constant, also known as the electric force constant or the electrostatic constant (abbreviated ke, k, or K), is a proportionality constant. It is equivalent to 8.9875517923(14)×109 (9*109)kg⋅m3⋅s−2⋅C−2 in SI units.

Since the galvanometer’s coil has a low resistance by itself, it needs to have its resistance raised in order to be converted into a voltmeter. This is accomplished by connecting a suitable high resistance in series with the galvanometer.

Balmer, Paschen, Brackett, Pfund, and Lyman are the five spectral series. The electron returns to n = 1 in the Lyman series. The obtained spectral lines fall within the electromagnetic spectrum’s ultraviolet region. The electron returns to n = 2 in the Balmer series, and the resulting spectral lines fall within the visible portion of the electromagnetic spectrum. The infrared portion of the electromagnetic spectrum yields the Paschen, Brackett, and Pfund spectral lines.

T=1/F

T = 1/20×10-6

F is 50000 Hz.
