It has been suggested that an asteroid, that when striking the Earth, vaporized a large quantity of soil, rocks, including itself. This resulted in a layer of material settling out relatively uniformly over the surface of the globe. Current evidence indicates 22% of the mass of the asteroid turned to dust and resulted in about 0.022 g/cm2 of the Earth’s surface being covered. A. If the asteroid had a density about 2.0 g/ cm^3 and the area of the Earth is 510.1 trillion m^2 calculate the mass of the asteroid.
B. Calculate the radius of the asteroid. What shape would you have to assume the asteroid is to do this?

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.

thermal energy is the answer

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

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