An electron traverses a vacuum tube with a length of 2 m in 2 X 10- 4 sec. What is the average speed of the
electron during this time?

Explanation:

Given that,

The length of a vacuum tube, d = 2 m

Time,

We need to find the average speed of the  electron during this time. Average speed is equal to total distance covered divided by total time taken.

Here, total distance = length of the vacuum tube

So, the average speed of the electron is .

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
