Answer:
Most wild races do not understand how the galaxy works. Let's see how well humans interpret a simple observation. The fact that we find O and B stars in the disk of our galaxy but not in the halo suggests that if there is knowledge about the galaxy, because it is known that there are stars, planets, black holes, halos, however there is still no the necessary technology, for the investigation and the refutation of the theories that currently exist on the theme of the galaxy.
M= 100000 kg
a= 2m/s²
Use Newton's second law:
F=ma=100000kg • 2 m/s²
= 200000 N
Answer:
the potential energy of this body is 245 J.
Explanation:
Given;
mass of the body, m = 250 g = 0.25 kg
height from which the body was dropped, h = 100 m
acceleration due to gravity, g = 9.8 m/s²
The potential energy of this body is calculated as;
P.E = mgh
substitute the given values and solve for the potential energy of this body;
P.E = 0.25 x 9.8 x 100
P.E = 245 J.
Therefore, the potential energy of this body is 245 J.
1.97 E-7 m should be right. I took this a while ago.
