Two immersion heaters, A and B, are both connected to a 120.0-V supply. Heater A can raise the temperature of 1.00 L of water from 20.0*C to 90.0'C in 6.90 min, whereas heater B can raise the temperature of 5.80 L of water from 20.0*C to 90.0'C in 5.00 min. What is the ratio of the resistance of heater A to the resistance of heater B?Required information Object A has mass 77.0 g and hangs from an insulated thread. When object B, which has a charge of +120 nC, is held nearby, A is attracted to it. In equilibrium, A hangs at an angle 0 =7.20' with respect to the vertical and is 5.10 cm to the left of B. T A B where r = 5.10 cm and q1 = +120 nC. What is the charge on A? nc! Required information Object A has mass 77.0 g and hangs from an insulated thread.
