Aplanet has a mass of 5.68 x 1026 kg and a radius of 6.03 x 107 m. what is the weight of a 65.0 kg person on the surface of this planet?
a.
636 n
c.
475 n
b.
678 n
d.
656 n

To solve this problem, we must know the gravitational force of the planet. The equation would be,

This would calculate the force between two objects with masses m1 and m2 and the gravitational constant, G, is 6.67 x 10^-11 m3 s-2 kg-1 and with r as the distance between the objects.

Thus,

F = (6.67 x 10^-11 m3 s-2 kg-1) * (5.68 x 10^26 kg) * (65 kg) * ((1/6.03 x 10^7 m)^2)

F = 678 kg/s^2 or 678 N

Answer is letter B.

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
