Answer:
A) D = 146.34m
B) α = 33.07° south of west
Explanation:
In the diagram you can see the position after each displacement.
Point A will be at (-180,0) in rectangular coordinates
Point B will be at (-180,0) + (230*cos(45), -230*sin(45))=(-17.365, -162.635)
Point C will be at Pb + (280*sin(30), 280*cos(30)) = (122.635, 79.852)
The fourth displacement will therefore be: (-122.635, -79.852).
The module of this vector is 146.34m
And the angle is 33.07° south of west
Psychological disorder is a kind of disease, related to brain functioning, they are very different, but can't be distinguished at high level so they are not extremely different
In short, Your Answer would be: "False"
Hope this helps!
Answer:
1375J
Explanation:
The gravitational potential/potential energy of the at the top of the tree which is the energy by virtue of its position.
P.E = mgh
mass = m
Acceleration due to gravity = g
height = h
At the top of the tree, the value of h (height) is high resulting in the gravitational potential. When the cat lands on the ground, the value of h is zero, the the gravitational potential would be zero and all the potential energy have been converted to other forms of energy.
Therefore, the total gravitational potential store is equal to the maximum amount of energy that can be transferred which is equal to 1375J.
