Answer:
h = 2.15 m
Explanation:
We can use the third equation of motion here to find out the height from which the cat fell that is the height of the refrigerator.
where,
g = acceleration due to gravity = 9.81 m/s²
h = height of refrigerator = ?
vf = final speed of cat = 6.5 m/s
vi = initial speedof cat vertically = 0 m/s
Therefore,
<u>h = 2.15 m</u>

Answer:
Explanation:
Muscle cells are excitable; they respond to a stimulus.meaning they can shorten and generate a pulling force. When attached between two movable objects, such as two bones, contraction of the muscles cause the bones to move.It contains protein fibers which contract to make the cell shorter.

The work done by along the given path <em>C</em> from <em>A</em> to <em>B</em> is given by the line integral,
I assume the path itself is a line segment, which can be parameterized by
with 0 ≤ <em>t</em> ≤ 1. Then the work performed by <em>F</em> along <em>C</em> is
