Consider the hydrogenic plutonium atom (Z = 94) with all but one electron removed. (A) What energy is the transition from n = 2 to n = 1 in this atom? What is the wavelength is the photon with this energy? (B) Does this photon have a high enough energy to cause pair production? If not, estimate…
A 12000 N car is raised using a hydraulic lift, which consists of a U tube with arms of unequal areas, filled with incompressible oil of density 800 kg/m3 and capped at both ends with tight fitting pistons. The wider piston has radius .18 m and smaller piston had radius .05 m. The car rests on…
A long silver rod of radius 3 cm has a charge of −5𝜇C/cm−5μC/cm on its surface. (a) Find the electric field at a point 5 cm from the center of the rod (an outside point). (b) Find the electric field at a point 2 cm from the center of the rod (an inside point).
Problem 1. (24 points) For each section below, in the absence of dielectric or magnetic materials, write Maxwell’s equations in integral form. Below each equation, provide a description of each equation. Your response will be graded on how efficiently you: (1) translate each equation into words…
An airplane pilot wants to fly at a speed of 400 mph directly West. However, there is a constant wind blowing at 30 mph from the SouthEast. Determine the speed and direction the pilot must fly to compensate for the wind and achieve the desired velocity. Complete the following with at least 2…
A thin, uniform, metal bar, 2.00 m long and weighing 90.0 N, is hanging vertically from the ceiling by a frictionless pivot. Suddenly it is struck 1.50 m below the ceiling by a small 3.00-kg ball, initially traveling horizontally at 10.0 m/s. The ball rebounds in the opposite direction with a…
Delores finds a nice open field area on the NMSU campus next to Interstate 10 where she likes to practice hitting golf balls. She is getting pretty good. At one point she decides not to just hit golf balls into the field, but to see how far she can blast and bounce a ball down the interstate…
A metallic sphere has a charge of +4.00 nC. A negatively charged rod has a charge of −6.00 nC. When the rod touches the sphere, 2.78 × 109 electrons are transferred. Elementary charge is 1.602 × 10−19 C. What is the charge on the sphere after the electrons were transferred? Answer in nC
(b) Consider a fixed quantity of an ideal gas undergoing a temperature increase from 28°C to 62°C. Analyze how the characteristics of heat absorption would differ between an isochoric process and an isobaric process achieving this same temperature change.
If (dC)/(dt)=-\alpha C, where C is the amount of caffeine in a person's body, t is time and \alpha is approximately 0.14hours^(-1), how many hours does it take for the body to metabolise half of the initial amount of caffeine?
An electron with a velocity of 17.4 m/s in the positive y-direction enters a region where there is a uniform electric field of 226 N/C in the positive x-direction. The mass of the electron is 9.109 × 10−31 kg. What is the y-component of the electron’s displacement 3.80 μs after entering the…
