- Gamma rays (?-rays) are high-energy photons. In a certain nuclear reaction, a ?-ray of energy 0.836 MeV (million electronvolts) is produced. Compute the frequency of such a photon. How do I enter 2.02*10^20 in the answer window?Using partial derivatives, calculate the propagated uncertainty in the mass in the following case: given the centripetal force Fc = (20.0 ± 0.5) N, the angular velocity w = (29.2 ± 0.3) rad/s, and the radius R = (0.12 ± 0.01) m get the mass value,m = Fc / (w2R). Express the result in the form m = m + Δm ANSWER IS 0.20 +- 0.03 KGAS SAID, USE UNCERTAINTY PROPAGATION SHOWN IN THE IMAGEUsing partial derivatives, calculate the propagated uncertainty in the mass in the following case: given the centripetal force Fc = (20.0 ± 0.5) N, the angular velocity w = (29.2 ± 0.3) rad/s, and the radius R = (0.12 ± 0.01) m get the mass value,m = Fc / (w2R). Express the result in the form m = m + Δm ----------------------------------- THAT'S THE QUESTION ASKED, see the image for the answer. Also have a look at the second image, the blue one. --------------------------------------------------------------- Explain what is the 1/m just after the equals sign at the second line of the answer. Also, explain why the answer does not use the square root just like the blue image, of if it is using it. Then, say in which case should I use the partial derivate to calculate the uncertainty.

What should the maximum velocity be for the particle to be trapped, i.e., hit capacitor plates? [electron mass -mp= 9.1 × 10-31kg, its charge is q= −1.6 × 10−19C, the electric force is found as ? = ??]. Assume that electron flies right in the middle of a capacitor. 2. Find and plot its trajectory for this case (that is, case of maximum velocity).
