a. an unconstrained loop of wire containing an electric current, placed in an electric field will undergo motion. Why does this occur and what is this called? b. a solenoid's magnetic field lines look like those of a bar magnet, explain why.
What is the relationship between electric field and electric force? When do we use one over the other? Why would we need both?
3.3 Electric Heating 8 marks One of the other engineers has suggested that electric immersion heaters would be cheaper for heating the solution instead of the steam heat exchanger. a) If the site supply voltage is 414 V, 3-phase what would be the current required?[2] b) What would be the resistance of the heating element required for this duty? [2]...

Three point charges Q_1, Q_2 and Q_3 in the xy-plane have electric charges of q_1 = +1C, q_2 = - 0.5 C and q_3 = 2C respectively. The coordinate of charge Q_1 is (0/2), the coordinate of Q2 is (-2,1) and the coordinate of...
Chapter 16, Problem 051 Two waves are generated on a string of length 3.8 m to produce a three-loop standing wave with an amplitude of 3.6 cm. The wave speed is 115 m/s. Let the equation for one of the waves be of the form y(x, t) ym sin (kx + at). In the equation for the other wave, what...
Question 6 (3 points) An earthquake emits both S-waves and P-waves which travel at different speeds through the earth. An S-wave travels at 5000 m/s and a P-wave travels at 9000 m/s. If S-waves are received at a seismic station one minute after a P-wave arrives, then how far away is the earthquake center? 88.9 km 240 km 480 km...
