Answer:
Because the mass of the the earth is way bigger than the mass of a classmate
Explanation:
Formula for force of gravity is;
F = Gm1•m2/r²
Where m1 and m2 are the two objects masses in question.
So, m1 may be your mass while m2 may be either the mass of the earth or your classmate.
The bigger the mass of m2, the more the force of gravity
Mass of the earth is about 5.97 × 10^(24) kg is which is so much more bigger than that of the classmate which is a human being.
Therefore, the reason why you may feel the effect of the gravitational forces between you and Earth, but not between you and a classmate is probably because the mass of the the earth is way bigger than the mass of a classmate
Answer:
Cyclic electron flow uses just PS I and creates ATP.
Explanation:
Photo-system is known as light-absorbing complexes which are present on the thylakoid membrane of the photosynthetic organisms. A molecule called P700 which is present on PS l and absorb light of approximately 700 nm.
Cyclic electron flow has excited electrons from the photochemical reaction center (P700) in Photo-system I that is passed from Ferrodoxin to the cytochrome complex and back to the photochemical reaction center. Cyclic electron flow only uses PS I and produces ATP, not O2 or NADPH.
