I’m trying to get my points up I have the same question
Answer:
Explanation:
According to Newton's laws of gravitation force of attraction is given by
F = GMm/R²
G = 6.67 X 10⁻¹¹
,M = 2.5 Kg ,
m = 2.5 Kg ,
R = .14 m
=
F = 6.67 X 10⁻¹¹ X 2.5 X 2.5 / 0.14²
= 2126.9 X 10 ⁻¹¹ N.

Answer:
The young tree, originally bent, has been brought into the vertical position by adjusting the three guy-wire tensions to AB = 7 lb, AC = 8 lb, and AD = 10 lb. Determine the force and moment reactions at the trunk base point O. Neglect the weight of the tree.
C and D are 3.1' from the y axis B and C are 5.4' away from the x axis and A has a height of 5.2'
Explanation:
See attached picture.
a =12miles
b =10miles
ab =2miles
Explanation:
at first the car is drown out of dealership and went 10 miles east and then 8 miles south
then your friend drives 8 miles west and 6 miles north.
then the distance it flies to get back to dealership is
10²+8 ²=12miles
8²+6²=10miles
12-10= 2 miles
