Two equilateral triangular parallel plates (side length = 50mm) facing each other
experiences a flux of 900Nm2/C . If a
phosphorus nucleus is placed the
positively-charged plate, what is the
velocity of the nucleus as it traverses the
electric field if the distance between the
plates is 60nm. Assume that the electric
field is perpendicular to the triangular
plates.

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?

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.

Which of these is the best way to manage a natural resource
