1.) Chemical energy
2.) Kinetic energy
Answer:
a. U = 1.68 μJ
b. i = 7.39 mA
Explanation:
a.
The energy total of the circuit can be find using
U = Q ² / 2 * C
Q = 3.56 μC
C = 3.77 μF
U = (3.56 μC ) ² / 2 * 3.77 μF
U = 1.6808 x 10 ⁻⁶ J
U = 1.68 μJ
b.
Now to determine the current in the circuit
U = ¹/₂ * L * i²
i² = 2 * U / L
i = √ 2 * U / L
i = √2 * 1.68 μJ / 61.5 mH
i = 7.39 mA
Dividing x^3 - 3x^2 - 4x + 12 by x + 2 gives
x^2 -5x + 6
= (x - 3)(x - 2)
so remaining factors are x - 3 and x - 2 answer
Answer:
0.68 m
Explanation:
We know that the speed of sound in air is a product of frequency and wavelength. Taking speed of sound in air as 340 m/s
V=frequency*wavelength
Then wavelength is given by 350/500=0.68 m
Therefore, to repeat constructive interference at the listener's ear, a distance of 0.68 m is needed
