Answer:
15.76°
Explanation:
Hi!
Let C~ = A~ + B~
Then
C~ dot A~ = |C| |A| cos Ф
C~ dot A~ = (A~ + B~) dot A~ = |A|^2 + |B| |A| cos(120)
Therefore
cos Ф = (|A| + |B| cos(120)) / |C| = 15.65/|C|
and
|C|^2 = |A|^2 + |B|^2 + 2 |B| |A| cos(120)
|C| = 16.261
cos Ф = 15.65/16.261
Ф = 15.76°

Answer:
The weight is the same
3
lb
explanation
See explanation.
Explanation:
If by weight you mean the physical value measured in
l
b (or k
g
) usually called mass, then this value does not depend on a place where object is located. Object's mass would be the same everywhere even if you put it on Mars or the Sun.
The value which changes is the gravitational force. In your example it is
10
2
=
100 times greater on the Earth's surface than in the point 10 Earth's radii from its center.
