Question

(a) What is the magnitude of current i? (b) How much energy is dissipated by all four resistors in 2.85 min? 5. In the figure Ri-7.50 S2, R2=22.5 2, and the ideal battery has emf E= 13.1 V. ww R 6. In the figure the current in resistance 6 is i6= 1.36 A and the resistances are R1 R2=R3 1.82 2, R4 = 14.6 2, Rs= 8.85 2, and Re the ideal battery? 4.43 Q. What is the emf of R 7. A particle of mass 9.59 g and charge 80.3 pC moves th rough a uniform magnetic field, in a region where the free - fall acceleration is -9.8 m/s2 without falling. The velocity of the particle is a constant 21.9 km/s, which is perpendicular to the magnetic field. What, then, is the magnetic field? 8. An electron moves through a uniform magnetic field given by B Bxi+(2.70 Bx)j. At a particular instant, the electron has velocity V = (2.66 i+4.93 j) m/s and the magnetic force acting on it is (4.27 x 10-19) k N. Find B
