A bar magnet whose dipole moment is (0, 0, 5) A·m2 has a constant velocity of (0, 0, 5) m/s. When the center of the magnet is at location (1, 3, 4) m, what is the (vector) electric field at location (1.03, 3, 3) m?

What are two different ways you could find the value of a? explain these methods.

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?
