Increase .... decrease .... presumably it's the "best shape" for a body which has been formed by the gravitational force
Replacement teeth were made even back then out of primitive materials, and pig hair was used like floss
Answer:
After we satisfy our basic needs, they no longer serve as motivators and we can begin to satisfy higher-order needs. Maslow organized human needs into a pyramid that includes (from lowest-level to highest-level) physiological, safety, love/belonging, esteem, and self-actualization needs.
Explanation:
Answer:
Vertical acceleration 9.8 m/s² downward
Horizontal acceleration 0.0 m/s²
assuming no air resistance.
Answer:
1.6 m/s2
Explanation:
Let 
be the gravitational acceleration of the moon. We know that due to the law of energy conservation, kinetic energy (and speed) of the rock when being thrown upwards from the surface and when it returns to the surface is the same. Given that stays constant, we can conclude that the time it takes to reach its highest point, aka 0 velocity, is the same as the time it takes to fall down from that point to the surface, which is half of the total time, or 4 / 2 = 2 seconds.
So essentially it takes 2s to decelerate from 3.2 m/s to 0. We can use this information to calculate
So the gravitational acceleration on the Moon is 1.6 m/s2
