An scale is the factor by which actual features on ground are enlarged or reduced for representing on a plane. There are different kinds of scales:
Verbal scale use of words to represent scale information on the map. The distance or linear units are used for depicting this scale on the map. For example: 1 inch = 1 Kilo meter.
Fractional scale uses the numbers or values for showing the scale instead of words. As the name says, it is represented using a fraction or ratio. Example: 1: 10,000 or 1/10,000
In large scale more details are shown in a map, however, less area coverage will be shown in a single map as the scale is large and more details are given. Example: 1:500
Small scale is exactly opposite to the large scale, less details are shown as magnification is not enough, however a large amount of area can be shown in a single map. Example: 1:25,000
A graphic scale is a bar that has been calibrated to show map distances. On maps that have been reduced or enlarged the original ratio and written scales are incorrect, since the relationship between map distance and real world distance has been altered, graphic scale is enlarged or reduced to the same extent as the map, this makes it the right option.
I hope you find this information useful and interesting! Good luck!
Let the charges be - Q₁ and Q₂ . Let the distance between them be d .
Potential energy = k -Q₁x Q₂ / R
= - KQ₁ Q₂ / R
Now if the magnitude of R decreases , the magnitude of potential energy increases . So we see that the negative potential energy becomes more negative .
Acceleration of the car driven by Ariana = 4.6 m/s^2 Time taken to reach this acceleration = 10 seconds Let us assume the final velocity of the car (V2) = x m/s Initial velocity of the car driven by Ariana (V1) = 0 m/s Then Acceleration = (V2 - V1)/ Time taken 4.6 = (x - 0)/10 4.6 = x/10 x = 4.6 * 10 m/s = 46 m/s So the final velocity of the car Ariana was driving was 46 meters per second.
