The magnitude of the magnetic flux through the surface of a circular plate is 6.00 10-5 t · m2 when it is placed in a region of uniform magnetic field that is oriented at 31.0° to the vertical. the radius of the plate is 8.50 cm. determine the strength of the magnetic field.

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
