Answer:
T1 = 675 [N] ; T2 = 707.5 [N]
Explanation:
To solve this problem we must draw a free body diagram, where the bird is located, the posts and distances mentioned.
In the attached image we can see the free body diagram with different forces, angles and distances.
By conducting a distance analysis we can find the angles on both sides of the rope relative to the horizontal.
Then we perform a force analysis on the X-axis and the y-axis in order to find the two equations we need to find the stresses in the cables (T1 & T2)

Answer:
The law of conservation of energy is the preserved form of energy.
Option (1) is correct that is the total amount of energy in the universe remains constant.Because energy is conserved.
Option (3) is correct since, it is conserved so, it can not be created or destroyed.
Option (4) Energy can change from one type to another like mechanical to electrical energy but it will remain conserved.
Option (5) is correct because in closed, isolated system energy is conserved.
