LC oscillators have. been used to circuits. connected to loud speakers to create some of the sounds of electronic musc. What indductance must be usedd with a 6.7 uF capacito r to prodice a frequncy of 10

Explanation:

Given the capacitor is used in an LC circuit to produce frequency.

We need to find the value of inductance required.

As we know the relation between angular frequency in and frequency in is.

Where is angular frequency and is frequency.

Also, the relation between the angular frequency, capacitance and inductance is given by.

So, inductance will be required to produce .

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
