<h3><u>Answer;</u></h3>
producing a path for current to flow
<h3><u>Explanation;</u></h3>
- An AC generator is a device that converts mechanical energy into electrical energy using the principle of electromagnetic induction.
- <em><u>Slip rings are two hollow rings to which two ends of the armature coil are connected. These rings rotate with the rotation of the coil. They function to to allow for electrical contact with the brushes.</u></em>
- Slip rings therefore, provide a means for connecting the rotating armature to an external circuit.
I'll go ahead and answer the ones here without an answer. For reference, the half-life formula is <em>final amount = original amount(1/2)^(time/half-life)</em>

4) 12.5g
x = 100(1/2)^(63/21)
5) 50g
3.125 = x(1/2)^(0.1/0.025)
6) 500g
x = 4000(1/2)^(525/175)
7) 0.24g
0.06 = x(1/2)^(11430/5730)
8) 125g
x = 1000(1/2)^(17100/5700)
Hope this helps! :)
Answer:
<u><em>375 J</em></u>
Explanation:
<u><em>Total energy</em></u> = 750 J
<u><em>Efficiency</em></u> = 50%
<u><em>Wasted energy</em></u> = 50% [100% - 50%]
<u><em>Amount of wasted energy</em></u>
= 750 x 50%
= 750 x 0.5
= 375 J
Answer:
The name of the file is Floppy.
Explanation:
Given that,
The disk that BTK sent to the television station contained just one valid file.
We need to find the name of the file
According to given data,
The disk that BTK sent to the television station contained just one valid file.
This file is called floppy.
Floppy :
The floppy disk is storage disk. It is made of thin and flexible disk of magnetic storage, It shape of square.
Floppy disk are read and written to by floppy drive.
Hence, The name of the file is Floppy.
Answer:
The total resistance is 106 Ω and the current in the circuit is 0.11 A.
Explanation:
Given that,
Voltage of the battery, V = 12 V
Resistors 34 Ω, 42Ω, and 30Ω are connected in series.
The total resistance is given by :}
R = 34 + 42 +30
= 106Ω
Let I is the total current in the circuit. Using ohm's law to find it such that,
Hence, the total resistance is 106 Ω and the current in the circuit is 0.11 A.
