Acceleration I think if I’m not mistaken
Explanation:
The weight of an object on the surface of the earth is equal to the gravitational force exerted by the earth on the object.
which gives us an expression for the acceleration due to gravity <em>g</em> as
At a height h = R, the radius of a satellite's orbit is 2R. Then the acceleration due to gravity 
at this height is
Simplifying this, we get
D. endothermic
Explanation:
Since the chemosynthesis reaction uses up heat and other inorganic compounds to produce food for themselves, the process is endothermic.
- In an endothermic reaction, heat is absorbed from the surrounding.
- The surround will then become colder at the end of the reaction.
- Since the chemosynthesis reaction uses up heat, it is an endothermic reaction.
- Exothermic reactions liberates heat to the surrounding.
- The surrounding becomes hotter at the end of the change.

The correct answer would be cells
Note that the centripetal force is proportional to the square of the velocity, implying that a doubling of speed will require four times the centripetal force to keep the motion in a circle.
