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
the purpose of using a chemical equation is to know the reactants and products that occur.
reactants=starting material
products=end result
1. Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery.
2. Insulation helps to prevent that transfer of heat. Many different materials are used for insulation. Engineers often use fiberglass, wool, cotton, paper (wood cellulose), straw and various types of foams to insulate buildings. A layer of trapped air can serve as insulation, too!
3. I'm not sure. Sorry
Answer:
The second system must be set in motion seconds later
Explanation:
The oscillation time, T, for a mass, m, attached to spring with Hooke's constant, k, is:
One oscillation takes T secondes, and that is equivalent to a 2π phase. Then, a difference phase of π/2=2π/4, is equivalent to a time t=T/4.
If the phase difference π/2 of the second system relative to the first oscillator. The second system must be set in motion seconds later
<span>CH4 I assume you're doing a test or something but I'm not good at explaining things so hopefully it's multiple choice! </span>
