PLEASE ANSWER ASAP11 Mitchell plays a trading card game. He has the starter pack of cards and adds to his collection by purchasing a booster pack each week that contains the same number of cards. On the graph, points are plotted and a line is drawn through the points to show the linear relationship between the total number of cards in Mitchell’s collection and the number of weeks he has been collecting. a. What is the initial value of the function represented by the graph?

b. What is the rate of change of the function represented by the graph?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
