Answer:
The movement of an object depends on the reference frame, so it is important to predicate it.
Explanation:
I believe the answer is elements!!!!
It forms a protective and adaptive barrier around a cell and this keeps various bacterial and viral intruders out. They also help in keeping cell systems inside the cell. The shell absorbs viruses and bacteria for nutrients when they do not have a certain strand to get inside the cell or trick it otherwise. Hope this helped!
The angle measured counterclockwise from the positive x-axis is θ = 50.4°

How to get the angle correspondent to a vector?</h3>
Here we know that the vector is:
V = < -177 cm, -214 cm>
To get the correspondent angle for this vector, we can think that this is the hypotenuse of a right triangle, such that the y-component and x-component are the cathetus.
Then, to get the angle (measured counterclockwise from the positive x-axis) is given by:
Tan(θ) = (opposite cathetus)/(adjacent cathetus)
Tan(θ) = (-214cm)/(-177 cm)
Using the inverse tangent function we get:
Atan(Tan(θ)) = Atan((-214cm)/(-177 cm))
θ = 50.4°
So the angle is 50.4°

Answer:
It lowers.
Explanation:
Friction causes energy to be converted to heat and released therefore lowering the energy the object has going towards it's velocity.
