Professor Newton decided to hang a physics sign above the door of his lab. Two wires of equal length attached to a heavy uniform rod hang vertically as shown in the picture below. The sign of negligible mass is attached to
the 4.3 kg horizontal rod of length r. The wire on the left (T) is attached to the end of the rod. The wire on the
right (T2) is attached at a distance of 24 cm from the right end of the rod. The length of the rod is 68 cm.

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.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
