Please help me:)Three identical conducting spheres, I, II, and III, are mounted on insulating stands and placed as shown above. Spheres I and II are each uncharged, and III carries a positive charge. Spheres I and II are connected to each other by a conducting wire. After the wire is removed, sphere III is moved far away. Which of the following statements about the subsequent charges on spheres I and II is correct?A. Sphere I is positively charged and sphere II is negatively charged.B. They are each still uncharged.C. They are charged with equal negative charges.D. They are charged with equal positive charges.

One strategy in a snowball fight is to throw a snowball at a high angle over level ground. While your opponent is watching this first snowball, you throw a second one at a low angle timed to arrive before or at the same time as the first one. Assume both snowballs are thrown with a speed of 34.8 m/s. The first one is thrown at an angle of 70 with respect to the horizontal.At what angle should the second snowball be thrown to arrive at the same point as the first?Answer in units of degrees
