What is the main difference between an analog voltmeter and an analog ammeter?
What would happen if you mistakenly used an ammeter where you needed to use a voltmeter?22Q23Q24Q1P2P3P4P5P6P7P8P9P10P11P12P13P14P15P16P17P18P19P20P21P22P23P24P25P26P27P28P29P30P31P32P33P34P35P36P37P38P39P40P41P42P43P44P45P46P47P48P49P50P51P52P53P54P55P56P57P58P59P60P61P62P63P64GP65GP66GP67GP68GP69GP70GP71GP72GP73GP74GP75GP76GP77GP78GP79GP80GP81GP82GP83GP84GP85GP86GP87GP1Q2Q3Q4Q5QTwo iron bars attract each other no matter which ends are placed close together. Are both magnets? Explain.7Q8Q9Q10Q11Q12Q13. Explain why a strong magnet held near a CRT television screen (Section 17-10)causes the picture to become distorted. Also, explain why the picture sometimes goes completely black where the field is the strongest. [But don’t risk damage to your TV by trying this.]
14Q15Q16Q17QIf a moving charged particle is deflected sideways in some region of space, can we conclude for certain, that B0 in that region? Explain.19Q20Q21Q22Q23QWhy will either pole of a magnet attract an unmagnetized piece of iron?25Q26Q27Q28Q29Q30Q31Q1P2PA 240-m length of wire stretches between two towers and carries a 120-A current. Determine the magnitude of the force on the wire due to the Earth’s magnetic field of 5.0× 10-5 T which makes an angle of 680 with the wire.4P5P6P7P8P9P10P11PFind the direction of the force on a negative charge for each diagram shown in Fig. 20-52 0:where (green) is the velocity of the charge and B (blue) is the direction of the magnetic field. (& means the vector points inward. © means it points outward, toward you.)13P14P15P16P17P18P19P20P21P22P23P24P25P26P27P28P29P30P31P32P33P34P35P36P37P38P39P40P41P42P43P44P45P46P47P48P49P50P51P52P53PA circular coil 12.0 cm in diameter and containing nine loops lies flat on the ground. The Earth's magnetic field at this location has magnitude 5.50 x 10-5T and points into the Earth at an angle of 56.0° below a line pointing due north. If a 7.20-A clockwise current passes through the coil, (a) determine the torque on the coil, and (b) which edge of the coil rises up: north, east, south, or west?55P56P57P58P59P60P61P62P63P64P65P66P67GP68GP69GP70GP71GP72GP73GP74GP75GP76GP77GP78GP79GP80GP81GP82GP83GP84GP85GP86GP87GP1Q2Q3Q4Q5Q6Q7Q8Q9Q10Q11Q12Q13Q14Q15Q16Q17Q18Q19Q20Q21Q22Q23Q24Q
