Answer:
Lighting bolts are sources of electric energy that change over time producing field of magnetic energy that also changes over time. So, when this field passes through a coil or loop of wire in an installation. It can create an induced emf that can transform into an induced current.
Explanation:
Lighting bolts are phenomenons made of pure electric energy that by correlation conduce a current. Now, this type of current by being electric can create an electromagnetic field of energy. Which at the same time will change over time because it derives from the electric source of energy originated in the lighting bolt. Thus, when this magnetic field that is always in movement passes through a coil or loop of wire will create an induced

Answer:
(a) W = 1329.5 J = 1.33 KJ
(b) ΔU = 24.27 KJ
Explanation:
(a)
Work done by the gas can be found by the following formula:

where,
W = Work = ?
P = constant pressure = (0.991 atm)(
) = 100413 Pa
ΔV = Change in Volume = 18.7 L - 5.46 L = (13.24 L)(
) = 0.01324 m³
Therefore,
W = (100413 Pa)(0.01324 m³)
<u>W = 1329.5 J = 1.33 KJ</u>
<u></u>
(b)
Using the first law of thermodynamics:
ΔU = ΔQ - W (negative W for the work done by the system)
where,
ΔU = change in internal energy of the gas = ?
ΔQ = heat added to the system = 25.6 KJ
Therefore,
ΔU = 25.6 KJ - 1.33 KJ
<u>ΔU = 24.27 KJ</u>
In electronics, the SI unit for current is Ampere. It is the amount of charge in Coulombs per unit time. It is named after the father of electrodynamics, Andre-Marie Ampere. Also, the current can be easily determined through the Ohm's Law, which states that current is equal to volts divided by the resistance. The answer is letter D.
