Suppose that in the previous problem (Q4 as given above), the magnetic field intensity in material (1) with the same current sheet (i. e., the total field in material (1) due to all sources, including the current sheet) is given as H1 = a 10° + ay 2x10 + a, 10+ [A/m]: (a) What is now the magnetic field intensity in material (2). (b) Discuss the difference between the solution to this problem and the previous problem.

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
