Your answer is partially correct. At a certain location, the horizontal component of the earth's magnetic field is $2.9 \times 10^{-5}$ T, due north. A proton moves eastward with just the right speed, so the magnetic force on it balances its weight. Find the speed of the proton. Number 1 Units m/s

Question 1 Multiple choice Is it possible for a system to have negative potential energy? Yes, since the choice of the zero of potential energy is arbitrary. No, because the kinetic energy of a system must equal its potential energy. No, because this would have no physical meaning. Yes, as long as the total energy is positive. Yes, as long as the kinetic energy is positive. 10 pts

Process P1 num = 0; turn = 1; loop1 = 0; while (loop1 < 3) while(turn != 1) //nothing num = num + 1; turn = 2; loop1 = loop1 + 1; Process P2 loop2 = 0; turn = 2; while (loop2 < 2) while(turn != 2) //nothing num = num + 10; turn = 1; loop2 = loop2 + 1; Assume all variables are shared for P1 and P2. This is a single-core system. We will start with num = 0. The CPU will execute 5 lines of code before switching processes. What is the value of num after both processes finish executing (or deadlocks)?

Future space stations may be designed to rotate in order to provide simulated gravity for their inhabitants. If the station rotates with a rotation rate necessary to simulate one-\half of earth's gravity at the outer ring with a distance of $R = 100$ m from the axis of rotation of the station, determine his simulated weight when he is in one of radial tunnels\and his distance from the center of the station is one third of $R$.
