calculate the area that will experience a force of 6000N from liquid exerting pressure of 300Pa. 1kPa=1000Pa

Explanation:

Pressure

Is a measure of how much force is applied perpendicular over a given area.

It is calculated by dividing the amount of force being applied F by the area over which it is being applied A:

The SI unit for pressure is the Pascal (Pa), equivalent to

A pressure of 300 Pa is being exerted over an area that experiences a force of 6000 N. We are required to calculate the value of the area.

If we know the pressure and the force, we solve the above equation for A;

Substituting the given values:

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.
