Identical 50 μc charges are fixed on an x axis at x = ±3.0 m. a particle of charge q = -15 μc is then released from rest at a point on the positive part of the y axis. due to the symmetry of the situation, the particle moves along the y axis and has kinetic energy 1.2 j as it passes through the point x = 0, y = 4.0 m. (a) what is the kinetic energy of the particle as it passes through the origin? (b) at what negative value of y will the particle momentarily stop?

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? a. the first law describes how thermal energy is conserved but not the direction it moves. b. the first law describes the direction thermal energy moves but not how it is conserved. c. the first law describes how thermal energy can be created but not how it can be destroyed. d. the first law describes how thermal energy can be destroyed but not how it can be created.
