Suppose you drop a rock at rest into a dark well and, using precision equipment, you measure the time for the sound of a splash to return. neglecting the time required for sound to travel up the well, calculate the distance to the water if the sound returns in 2.4700 s. then calculate the distance taking into account the time for sound to travel up the well. the speed of sound in this case is 340.00 m/s as well.

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.

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
