2. explain the relationship between the light reactions and the calvin cycle in photoautotrophs.

Explanation:

During photosynthesis, chlorophyll traps sunlight energy using photosystems (p680 and p700). This is converted into ATP and NADPH. The ATP supplies the energy needed for Calvin cycle while the NADPH gives the electrons need for conversion of carbon dioxide to sugar in calvin cycle.

lol

explanation:

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
