A horizontal wire carries a current straight out of the screen/page. The magnetic field as seen by you the observer at a point directly below the wire points Hint: RIght Hand Rule, magnetic force, cross product A) directly away from you. B) to the left. C) to the right. D) directly toward you. E) vertically upward.

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)

What is the increase in density of a medium due to wave travel?

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
