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.
The higher the solar activity, and the hotter it is, the more the oceans heat up and water evaporates into the atmosphere. High amounts of water vapor causes things like hurricanes. However, oceans have a high absorption rate of heat so they can absorb a lot of it without heating up the atmosphere, which is pretty good or else the Earth would overheat.
In salty water ions are produced by the salt
here salt is NaCl
so it will break in Na⁺ and Cl⁻
They carry the current
Na⁺ moves towards cathode and Cl⁻ moves towards anode
So current is carrying by ions which are Na⁺ and Cl⁻
Answer:
Radius of orbit = 3.992 ×
m
Altitude of Satellite =33541.9× m
Explanation:
Formula for gravitational force for a satellite of mass m moving in an orbit of radius r around a planet of mass M is given by;

Where G = Gravitational constant = 6.67408 × 10-11 
We are given
F= 800 N
m = 320 Kg
M = 5.972 ×
Kg
G = 6.67408 × 10-11 
We have to find radius r =?
putting values in formula;
==> 800 =6.67408 ×
× 320 × 5.972 ×
/ 
==> 800= 39.8576 ×
× 320 / 
==> 800 = 12754.43 ×
/ 
==>
= 12754.43 ×
/800
==>
=15.94 ×
==> r = 3.992 ×
m
==> r = 39920×
m
This is the distance of satellite from center of earth. To find altitude we need distance from surface of earth. So we will subtract radius of earth from this number to find altitude.
Radius of earth =6378.1 km = 6378.1 ×
m
Altitude = 39920×
- 6378.1 ×
