What is one way phosphorus leaves the biosphere?
a. by animals eating plants
b. by forming from a solution
c. through animal waste
d. through weathering

answer:

explanation:

phosphorus enters the biosphere almost entirely from the soil through absorption by plant roots.

weathering of rocks containing phosphate minerals

so the answer is

option d

d. through weathering

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
