98. * An electron enters a bubble chamber and produces a spiral track like that shown on the left in Figure Q20.13. The magnetic field is directed into the page, and the electron had an initial velocity of 2.7 x 108 m/s. (a) If the initial radius of the electron's trajectory is 5.0 cm, what is its velocity when it has spiraled in to have a path with radius 2.0 cm? (b) What is the correspond- ing change in kinetic energy? Give your answer in joules and electron-volts. (c) Calculate the magnitude of the magnetic field present in the bubble chamber. (d) What is the change in force on the electron in going from the initial radius to the final radius?

The average bond enthalpies of the C—F and C—Cl bondsare 485 kJ/mol and 328 kJ/mol, respectively. (a) What isthe maximum wavelength that a photon can possess andstill have sufficient energy to break the C—F and C—Clbonds, respectively? (b) Given the fact that O2, N2, andO in the upper atmosphere absorb most of the light withwavelengths shorter than 240 nm, would you expect thephotodissociation of C—F bonds to be significant in thelower atmosphere?
In the problem 15 above, what is vy , the y-component of the electron’s velocity, when it has reached the right edge of the plates? Note that ay=vyt (be careful with the sign). How is the ratio S/L related to vx and vy , if vy is calculated at the right edge of the plates? The distances S and L are shown in Figure 1.11.
Pls pls help me asap with the following question and make sure it’s right 1000%% explain and thank you
In a vacuum chamber filled with argon gas at 100 mTorr, a plasma is ignited resulting to 1% ionization. This is already a "hot plasma" by lab processing standards. Calculate the number density of plasma electrons (should be about the same as the argon ion density due to quasineutrality) in this 1% ionized plasma.
