Answer:
Explanation:
As we know that electrostatic potential energy of the electron is converting here into kinetic energy
so we will have
so here we know that
so from above equation we have
The mean height for the grass used as a control is equal to the total number of the data came from the control grass divided by the number of control grass in the experiment. The mean height means the average height of the grass.

Answer:
The dotted line connecting two points is known as the distance traveled.
Explanation:
The distance traveled is a physical quantity that refers to the total displacement of a body. This distance is usually shown as a dotted line that connects two points in an image. In general, we can say that the distance traveled is calculated by adding all the distances that an element makes when leaving one point and reaching another point, which is its final position.
An example of this can be seen in the image shown below, where the red line represents the displacement of a body that left point A and arrived at point B. The blue dotted line represents the distance traveled and refers to the total displacement of that body, showing all the distances it covered while walking from point A to point B.
