The size of the star defines wither of not it is a dwarf star, or a red giant.
Accuracy is a general concept while precision is more of a mathematical concept.
Your answer is 7.009m/s
If you would like to show how I solved this just ask. :)
Hope this helps -John
Answer:
<em>The weight is 348.4 N</em>
Explanation:
<u>Effect of the Altitude on the Acceleration of Gravity</u>
The effect of gravity decreases with altitude because greater altitudes mean greater distances from the Earth's center.
The practical formula to calculate the gravity as a function of the altitude h is:

Where go is the conventional gravitational acceleration = 
R is the Earth's mean radius at the equator = 6,378 Km
h is the altitude.
At a height of h=800 Km, the acceleration of gravity is:

Calculating:

The weight is the product of the acceleration of gravity by the mass of the object, thus:

The weight is 348.4 N
