Law enforcement officers use radar guns based on the Doppler effect to measure the speed of automobiles. Explain why the details of the Doppler effect make it desirable for the officers to park near the road in a place without curves
What will be an ideal response?
A doubly charged ion with speed 6.9 × 106 m/s enters a uniform 0.80-T magnetic field, traveling perpendicular to the field. Once in the field, it moves in a circular arc of radius 30 cm
What is the mass of this ion? (e = 1.60 × 10-19 C) A) 3.3 × 10-27 kg B) 6.7 × 10-27 kg C) 8.2 × 10-27 kg D) 11 × 10-27 kg
A little magnetic compass has a needle whose tips are clearly labeled N and S. The compass is placed next to a single circular loop of wire lying flat on a wooden table. The current in the loop is clockwise. What happens?
A. The S tip of the needle is attracted toward the loop B. The needle orients itself with the N tip pointing in the direction of the current in the segment of the loop closest to the needle C. The needle orients itself with the S tip pointing in the direction of the current in the segment of the loop closest to the needle D. The N tip of the needle is attracted toward the loop E. None of these choices are correct
