gurlll this need way more points
Answer:
Robbie's displacement is zero.
Explanation:
Displacement is called the change in position that a body experiences, from an initial point A, to an end point B, through movement. That is, displacement is understood as the length and direction that a body travels to move from an initial point to an end point. Displacement is a vector type quantity, which is described from the magnitude and the direction.
Only the start point and the end point are important for displacement. When the object ends at the same starting point, the displacement will be zero.
You know that Robbie leaves his house and drives 5 miles North to the post office, 8 miles East to the park, 5 miles South to the grocery store, and then 8 miles West to get back home.
<u><em>Since in this case the start point and end point is Robbie's house, then the offset will be zero.</em></u>

well its a productive activity that one takes part in due to being broke
The board is 2.50m high.
Why?
We can calculate how high was the board applying the Law of Conservation of Mechanical Energy. This Law states that the mechanical energy (kinematic and potential) will be conserved during the motion.
It can be described with the following formula:


At the top of the boar, the kinetic energy is equal to 0.
At the water, the potential energy is equal to 0.
So,

Hence, we have that the board is 2.50m high.
Have a nice day!
<u>Frequency is the number of waves that passes at a given point every second.</u> The lower the frequency, the less waves there are. The higher the frequency, the more waves. <u>A wavelength is the distance between two frequency waves. </u>The higher the frequency, the less distance from two waves. The lower the frequency, the longer distance from two waves.
