A planet has a mass of 5.97 x 1024 kg and a radius of 6.38 x 106 m. Find the weight of a 65.0 kg person at 1000 km above the sur

mote1985 [20]

Answer: The weight of the person above the surface of a planet is 635.83N.

Explanation:

To calculate the weight of a person, we use the formula:

$w=mg$ ....(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:

$g=\frac{GM}{r^2}$

where, g = acceleration due to gravity = $?m/s^2$

G = Universal gravitational constant = $6.67\times 10^{-11}Nm^2/kg^2$

M = mass of the planet = $5.97\times 10^{24}kg$

r = distance of the person from the planet = $6.38\times 10^6m$

Putting values in above equation, we get:

$g=\frac{(6.67\times 10^{-11}kgm/s^2.m^2/kg^2)(5.97\times 10^{24}kg)}{(6.38\times 10^6m)^2}\\\\g=9.782m/s^2$

Putting this value in equation 1, we get:

$w=65kg\times 9.782m/s^2=635.83N$

Hence, the weight of the person above the surface of a planet is 635.83N.

D - The organisms on the island are slightly different than those on the mainland.

The reason why this is the correct answer is because each successive generation on the mainland as well as the island both develop and continue adapting to their specific ecological niche and environment. They are, howerer, both still part of the same species.
