If the period of the oscillator were doubled, what would happen to the wavelength and wave speed?

If the period of the oscillator were doubled, the wavelength and the speed of the wave will reduce by 2.

The period of oscillation is given as;

where;

The period of the oscillator, wavelength and speed of the wave are inversely proportional.

Thus, from the equation above we can conclude that if the period of the oscillator were doubled, the wavelength and the speed of the wave will reduce by 2.

we can see how the government has failed them.

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.
