I’m pretty sure the answer is the first option, but I could be wrong
Answer:
The ANSWER you SEEK is A. MIXED
Explanation:
<span>Agriculture was key to the development of modern "civilization" because by being able to grow food rather than getting it through trade or hunting, people were able to stay in one place instead of having to be where the food was. This also led to jobs because people became highly skilled in growing crops.</span>
Answer:
The acceleration will vary with height.
Explanation:
According to the gravitational law the acceleration of a small body will be
g=GM/D^2
=(6.67×10^−(11))(6×10^(24))÷(6.4×10^6)^2
9.8m/s^2
The acceleration of an apple of 200 gram(assumed to be near the surface of Earth.) will be approximately 9.8 m per second square.
Acceleration of Earth can be calculated by this method.
According to the Newton's third law the force acting on that will be same as the force acting on the Apple. Let the mass of earth be M and the acceleration be A .and the mass of apple be m and acceleration of apple will be g.
Force on Apple = Force on earth
MG=mg
(6×10^(24))G=(0.2)×9.8
G=3.2667×10^(−25)m/s^2
hope it helped. :)
