Three point charges are placed at the corners of a right-angle triangle, as shown in the figure. The masses, charges and coordinates of the three objects are given as follows: Mass (g): Charge (μC): Coordinate (mm): ?1 = 2.30 ?1 = −1.25 ?1 = (0; 6.00) ?2 = 0.15 ?2 = +0.55 ?2 = (0; 0) ?3 = 1.50 ?3 = −2.05 ?3 = (4.00; 0) (a) Determine the coordinate of the centre of mass of the system. (b) Calculate...

(1 point) Let θ(in radians) be an acute angle in a right triangle and let xx and yy, respectively, be the lengths of the sides adjacent to and opposite θ. Suppose also that x and y vary with time. At a certain instant x=8 units and is increasing at 1 unit/s, while y=5 and is decreasing at 1/3 units/s. How fast is θ changing at that instant?
