Which of the following best explains why the biosphere is a key component of the earth’s systems? a. the biosphere is a key component of the earth’s systems because it is a common concept to many disciplines in science. b. the biosphere is a key component of the earth’s systems because the seasonal cycles directly affect primary productivity. c. the biosphere is a key component of the earth’s systems because it drive the other systems by interacting with and exchanging matter and energy with the other spheres. d. the biosphere is a key component of the earth’s systems because it has evolved to create the chemical composition of the planet we know today.

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
