Answer:
2.93 x 10⁻⁴ volts
4.88 x 10⁻⁵ A
Explanation:
N = Number of turns in cylindrical coil = 400
r = radius of the coil = 2 cm = 0.02 m
Area of the coil is given as
A = πr²
A = (3.14)(0.02)²
A = 12.56 x 10⁻⁴ m²
ΔB = Change in magnetic field = 0.13 - 0.06 = 0.07 T
t = time interval = 2 min = 2 x 60 sec = 120 sec
Induced emf is given as
E = 2.93 x 10⁻⁴ volts
R = resistance of the resistor = 6 ohm
i = induced current
Using ohm's law
E = i R
2.93 x 10⁻⁴ = i (6)
i = 4.88 x 10⁻⁵ A
The answer is C why because I know it is
Answer:
Resultant displacement is 240 feet west.
Explanation:
Consider that George starts at the origin of coordinates and walks to the left (west) to position 320 feet, then he turns around and walks to the right (east) for 80 feet.So he is now (320 - 80 = 240) feet from the origin but still to the left of it. This means he is 240 feet west from where he started.
Voltage, because the voltage applied to a resistor generates a current, which is the load flow.
Letter C

Answer:
r=2.743
Explanation:
The energy stored on a capacitor is of type potencial, therfore depends on the capacity to "store" energy. Inthe case of the capacitor, it stores charge (Q), and the equations you use to calculate it are:
In this case we know V and C, therefore we use the last expression:
r=2.743
