14. The large space telescope that has been placed into Earth orbit has an aperture diameter of 2.40 meters. What angular resolution will this telescope achieve for visible light with a wavelength of  m? Please show the unit in radians.

10. The figure shows three situations in which the same charged particle is surrounded by a concentric Gaussian sphere. (1) sphere has radius R (2) sphere has radius 2R  (3) sphere has radius 2R and also surrounds a neutral metal spherical shell Rank the three situations according to the magnitude of the electric flux through the surface of the Gaussian sphere, greatest first. NOTE:請依序排列,並加註大於、小於、或等於符號(＞, ＜, or =)。

11. In the following figure, we have V = 9.0 V, C2 = 3.0 µF, and C4 = 4.0 µF, and all the capacitors are initially uncharged. When switch S is closed, a total charge of 20 µC passes through point a and a total charge of 8.0 µC passes through point b. What is capacitance C3 (uF)? 

12. An alpha particle (q = +2e, m = ) travels in a circular path of radius 4.50 cm in a uniform magnetic field with B = 1.20 T. Through what potential difference (volts) was it accelerated (from rest) to have the kinetic energy required for this path?

13. The figure shows a conducting bar sliding at speed along a wire in the shape of "U" through a uniform magnetic field that is perpendicular to the wire and bar: speed = 3.0 m/s, left-right width L = 5.0 m, induced emf = 360 V counterclockwise. What is the magnitude (T) of the magnetic field? 

15. The figure shows two particles moving in the negative direction of an x axis past an observer. Relative to the observer, particle A moves at speed 0.950c and particle B moves at speed 0.900c. What speed will A measure for B? 

16. The following figure is a plot of stopping voltage versus light frequency f in a photoelectric experiment with a certain metal with a work function Ф. What is the slope?
