A jet plane is flying at a constant altitude. At time t1 = 0 it has components of velocity vx = 90 m/s, vy = 110 m/s. At time t2 = 30.0 s the components are vx = -170 m/s, vy = 40 m/s. (a) Sketch the velocity vectors at t1 and t2. How do these two vec- tors differ? For this time interval calculate (b) the components of the average acceleration, and © the magnitude and direction of the average acceleration.

Calculating Total Number of Protons and Electons in a Piece of Gold and its Total Charge. Particles in a Gold Ring. You have a pure (24-karat) gold ring with mass 17.7 g. Gold has an atomic mass of 197 g/mol and an atomic number of 79. (a) How many protons are in the ring, and what is their total positive charge? (b) If the ring carries no net charge, how many electrons are in it? coulombs law electromagnetism

Find Electric Field - Electromagnetism Physics. A charged paint is spread in a very thin uniform layer over the surface of a plastic sphere of diameter 12.0 cm, giving it a charge of -35.0 mC. Find the electric field (a) just inside the paint layer; (b) just outside the paint layer; (c) 5.00 cm outside the surface of the paint layer.

A point charge q1 = 4.00 nC is located on the x-axis at x = 2.00 m, and a second point charge q2 = -6.00 nC is on the y-axis at y = 1.00 m. What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius (a) 0.500 m, (b) 1.50 m, (c) 2.50 m?

Two plane mirrors intersect at right angles. A laser beam strikes the first of them at a point 11.5 from their point of intersection, as shown in the figure For what angle of incidence at the first mirror will this ray strike the midpoint of the second mirror (which is 28.0 long) after reflecting from the first mirror?
