<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.
<u>Explanation:</u>
To calculate the weight of a person, we use the formula:
....(1)
where,
w = weight of an object
m = mass of the person = 65kg
g = acceleration due to the gravity of the planet
For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:

where, g = acceleration due to gravity = 
G = Universal gravitational constant = 
M = mass of the planet = 
r = distance of the person from the planet = 
Putting values in above equation, we get:

Putting this value in equation 1, we get:

Hence, the weight of the person above the surface of a planet is 635.83N.
He is most likely to suffer some loss of visual perception.
The correct answer is:
Hydrostatic pressure will drop as blood moves away from the arteriole end of the capillary bed
Explanation:
The hydrostatic pressure is exerted by a fluid in a specific point as a consequence of the weight of this fluid. Since blood is a fluid, it presents a hydrostatic pressure. In consequence, the blood in the feet have more hydrostatic pressure than the blood in the heart
