Part A An electron has an initial velocity $\vec{v}_0 = (9.0 \times 10^4 \text{ m/s}) \hat{j}$. It enters a region where $\vec{E} = (2.0 \hat{i} + 8.2 \hat{j}) \times 10^4 \text{ N/C}$. Determine the vector acceleration of the electron as a function of time. Express your answer using two significant figures. Enter the x and y components of the acceleration separated by a comma. $a_x, a_y =$ m/s$^2$ Submit Request Answer Part B At what angle $\theta$ is it moving (relative to its initial direction) at $t = 1.1 \text{ ns}$? Express your answer using two significant figures. $\theta =$ Submit Request Answer Provide Feedback counterclockwise from the initial direction Next >

Digital movie projectors, several of which one person with a computer can operate simultaneously, have replaced nearly all 35mm projectors, each of which requires a dedicated projectionist, in movie theaters. The exception is movie theaters on college campuses, where projectionists are typically students eligible for work-study jobs. This makes sense if projectionists at colleges are paid than those in commercial movie theaters, which would the incentive for colleges to substitute capital for labor. more; increase less; increase more; reduce less; reduce Digital movie projectors, several of which one person with a computer can operate simultaneously, have replaced nearly all 35 mm projectors, each of which requires a dedicated projectionist, in movie theaters.

Prob.4a (8 pts) Incident photons strike a clean nickel surface (work function= applied, the photocurrent vanishes. [a](4 pts) What is the energy of the incident photon in units of eV? [b] (4 pts) What is the wavelength of the incoming light? Prob.4b (8 pts) A monochromatic light of wavelength = 500nm is sent into the Michelson interferometer. The two legs of the interferometer have length L and Lz as shown in the figure (L and L are the distances between semitransparent mirror Mo and mirrors Mi and M2, respectively. Light [i] (4 pts) What is the condition for constructive interference at the observer? My to change the length L by distance d. What is the minimum displacement d of mirror M that will result in a change from constructive to destructive interference at the observer?
