Select all that apply. which of the following are not essential parts of a circuit? conducting wires fuse source of electric potential ammeter

-- the FUSE is not essential, but it's a good idea for safety and protection

-- the AMMETER is not essential, but it can give you information that you can't get without it, about how the circuit is operating

-- the conducting wires and the source of electric potential are essential parts of a circuit; if you're missing either one of these, you have no circuit  

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.
