Answer:
Move the opposite direction ( at a lesser magnitude of velocity)
Explanation:
I believe the answer is B: It’s moving at a constant speed.
B they belong to the same family of elements
Answer:
Current = 15 A
Resistance = 7.33 ohm
Magnetic field = 1.62 x 10^-4 Tesla
Explanation:
V = 110 V, P = 1650 W, r = 1.85 cm,
(a) Let i be the current
P = V x i
i = 1650 / 110 = 15 A
(b) Let R be the resistance
V = i R
R = 110 / 15 = 7.33 Ohm
(c) Let B be the magnetic field
B = μ0 / 4π x 2i / r
B = 10^-7 x 2 x 15 / 0.0185 = 1.62 x 10^-4 Tesla
