A subatomic particle X spontaneously decays into two particles, A and B, each of rest energy 140 MeV. The particles fly off in opposite directions, each with speed 0.827c relative to an inertial reference frame S. Which expression gives the momentum of particle A (relative to frame S)?

If the area of a square has increased by a factor of 16, by how much has each side increased?

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?
