Before entering the cyclotron, the particles are accelerated by a potential difference V. Find the speed v with which the partic
vesna_86 [32]

Answer:

Speed, v=\sqrt{\dfrac{2qV}{m}}

Explanation:

The device which is used to accelerate charged particles to higher energies is called a cyclotron. It is based on the principle that the particle when placed in a magnetic field will possess a magnetic force. Just because of this Lorentz force it moves in a circular path.  

Let m, q and V are the mass, charge and potential difference at which the particle is accelerated.

The work done by the particles is equal to the kinetic energy stored in it such that,

qV=\dfrac{1}{2}mv^2

v is the speed with which the particles enter the cyclotron

So,

v=\sqrt{\dfrac{2qV}{m}}

So, the speed with which the particles enter the cyclotron is v=\sqrt{\dfrac{2qV}{m}}. Hence, this is the required solution.

Label A is showing___ frequency waves, and label B is showing ___ frequency waves
igomit [66]

It's not really possible to tell longitudinal vs. transverse in this image as given. However, we can say that the waves labeled A are high-frequency (short wavelengths) while the waves labeled B are low-frequency (long wavelengths). So, this third answer choice would be correct here.

xz_007 [3.2K]
An ionic compound is a substance that contains atoms that are bonded together through an ionic bond, where electrons are transferred from one atom to another. For the given experiment above, the material that is missing from the list is WATER or solvent. It is necessary because conduction through water will help you identify if a sample compound is ionic through its electrolytes. <span>Ionic compounds that are soluble are typically electrolytes</span>
