Answer:
C
Explanation:
Fusion and fission are similar in that they both release large amounts of energy. Nuclear fusion is a process in which two nuclei join to form a larger nucleus. Nuclear fission is a process in which a nucleus splits into two smaller nuclei.
Answer:
Induced current I = 0.44 A
Explanation:
given data
no of turn N = 18
radius = 27.0 cm
resistance of the coil = 4.50 Ω
time = 2.90 s
magnetic field = 1.90 T to 0.500 T
solution
we get Induced EMF that is
E = - dφ ÷ dt ..............1
E = - N × A × (B2 - B1) ÷ Δt
E = N × A × (B1 - B2) ÷ Δt
area of cross section of the coil A = π × r²
area of cross section = 3.14 × (0.27)²
area of cross section = 0.228 m²
Initial magnetic field B1 = 1.9 T
and
Final magnetic field B2 = 0.5 T
time Δt = 3.7 s
put here value and we get
E =
E = 1.98 V
and
Induced current I is express as
Induced current I = E ÷ R ................2
Induced current I =
Induced current I = 0.44 A
The first question is how much of a voltage increase are we looking at. If it has a 110 voltage rating and you put it across a 220 source, you will see one flash and then the bulb is no more. Nothing will revive it.
If it is rated at 110 and you put 130 across it, there's no problem but the bulb will burn out sooner than it would if you just put 110 across it.
So you raise the voltage and the resistance stays the same, the current will increase. That's why it will burn out sooner.
V = I * R
The equation is a direct variation. If the voltage goes up the current goes up. If the voltage goes down, the current goes down providing that the resistance stays the same in both cases.
The second question is what is resistance? Resistance in Electricity is the ability of an electric current to go in one direction freeing up as many electrons as it can. The MORE free electrons, the lower the resistance. The FEWER free electrons the higher the resistance.
Here' the kicker. Ready? More and Less are probably the two most important words in beginning science.
The <u><em>More</em></u> the resistance, the <em><u>Less</u></em> the current flow. That's a really important consideration in battery drain in a watch (or modern day calculator). The More the Battery Drain, the Less time it will last.
Always be careful when more and Less are around.
