Using both of the articles, answer the questions below. You can answer questions on a word processing document and upload it for grading, or you can submit answers to questions directly. Be sure to review the grading rubric before you begin.

Summarize the scientific information that leads to conservation in each of the articles.

What social issues affected the problem or its solution in each of the stories?

How did economics delay scientists' first attempts for conservation in each story?

Describe the political actions that led to successful conservation in both stories.

Ill give brainlist!!

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
