I would say the answer is Pangaea. I got this answer but google searching "all land" means what... and the 3rd or 4th one down it says Answers.com
But i worn you answers.com is a very slow sight...
Hope it helps
and please mark me as brainiest
Option D would be the correct one!
Answer:
144 watt
Explanation:
resistance, R = 100 ohm
L = 4 mH
C = 100 micro farad
At resonance, the impedance is equal to R
Z = R
Vrms = 120 V
Irms = Vrms / R = 120 / 100 = 1.2 A
Power is given by
P = Vrms x Irms x CosФ
Where, CosФ is called power factor
At resonance, CosФ = 1
Power, P = Irms x Vrms
P = 1.2 x 120 x 1
P = 144 Watt.
Thus, the power is 144 watt.
Consider the formula ...
Current = (voltage) / (resistance) .
If the resistance doesn't change, then the current is
directly proportional to the voltage.
If the voltage decreases to 1/3 of what it used to be,
then the current does the same thing.
1.2 A ----> 0.4 A
Answer:
If you ring the doorbell and no one opens the door, you'll infer that no one is home rather than continuing to ring the doorbell to an empty house. Being able to understand this and look for another solution is another example of mental flexibility.
