Explanation:
..........the answer is insulater
Answer:
<h3>
a)</h3>
<u>=> R= 6 Ohms(Ω)</u>
<h3>b)</h3>
<em>these lights operate at the usual 240 volts direct from the main electricity supply. Therefore,</em>
<em>R and 100 can interchange places</em>
<u>=> R = 576 Ω</u>
<u></u>
By Ohm's Law:
=> 240 = I × 576
=>
=> I = 0.417 A
<h3 /><h3>c)</h3>
I don't know it's resistance,... so sorry
<h3>d)</h3>
The brightness of the bulb in series is <em><u>less than</u></em> when they're placed individually.
For bulbs in series their resistance gets added to form the equivalent resistance of the two bulbs.
Their resistances are nothing but mere numbers and the sum of two numbers(positive of course) is greater than the numbers.
So, the effective resistance of some bulbs in series <u>is more</u> than the individual resistance.
And
<em>Brightness, i. e., Power</em>
If resistance increases, Power decreases.
Here, the effective resistance was for sure larger, therefore resistance was increasing, hence power decreased taking brightness along with it.
Answer:
The dead spot experienced was due to the effect of sound wave interference
Explanation:
Sound wave interference occurs when wave interact. They can interact constructive manner increasing each other's strength and rising the intensity of the final wave produced.The waves can also interact destructively reducing each other's strength and intensity.In some cases, destructive interaction causes a total cancelling of the waves resulting to places where no sound can be heard at all.This area is the dead spot.
Answer:
Answer is A) Fermi
Explanation:
Fermi is the expressive unit for nuclear sizes. Fermi = 10^-15 meter.
