1- Suppose that a single long wire carrieda current of 100 A. At a distance of 1 cm from the wire, what would be its magnetic field?

Match the following physics concept with the math expression that describes it. The symbols are the usual ones, and are on our class website. - v Power dissipated in a resistor a. 2k 1/R Capacitance b. 12R - v Magnetic field around a long straight wire - v Field inside a solenoid C. Ke qQ / R2 v Force on a moving charge d. q E - v Force on a stationary charge e. 4xk n/ m - v Force between two charges f. qv x B g. Q/VSuppose that a single long wire carried a current of 100 A. At a distance of 1 meter from the wire, how would its magnetic field compare to the field only 1 centimeter away? O At 1 meter would be the same that it would be at 1 centimeter. O At 1 meter it would be 1/10,000 what it would be at 1 centimeter. O At 1 meter it would be 100x stronger than it is a 1 centimeter. O At 1 meter would be 1/100th the field of what it would be at 1 centimeter.\fA charge is brought up next to a big metal plate. The electric field near the plate is O Zero O Perpendicular to the plate O Parallel to the plate O inclined at an angle to the plate that depends on how far the point on the plate is from the chargeWhen a voltage is applied to a conductor such as copper, the current that flows is limited by resistance. Which of these factors affects the resistance? Check all that apply. O The length of the conductor. The collision of electrons with atoms and the resulting scattering from their direction of movement. The properties of the conducting material, perhaps given as an empirical resistivity. The magnitude of the voltage, that is, the more voltage the less resistance there is. O The polarity of the voltage, that is which side of the material is positive and which is negative., or the direction of the current flow. O The limited cross sectional area of the conductor.O Use 1/2 the resistance for the North American model compared to the European model O Use 1/4 the resistance for the North American model compared to the European model O Use the same resistance for the North American model compared to the European model O Use twice resistance for the North American model compared to the European model
