For this case, the first thing you should observe is the variables:

Vertical axis: speed

Horizontal axis: time

Since the relationship between both variables is linear then we have that the slope of the line represents the acceleration according to the formula:

vf = a * t + vo

Where,

a: acceleration

t: time

vf: final speed

vo: initial speed

According to the equation, in the interval of 6 to 8 seconds, we observe that the slope of the Elan line is greater than the slope of the Anna line.

Therefore, for the 6 to 8 second interval, the Elan acceleration is greater.

From 6 to 8 seconds, Elan accelerated faster than Anna.

Answer from: sweetyus06

Explanation :

The given graph depicts the velocity-time graph for both Elan and Anna during a race.

In this velocity-time graph, it shows the acceleration of Elan and Anna for different time intervals.

We know that acceleration is defined as :

$a = \dfrac{v-u}{t}$

Where,

v is the final velocity

u is the initial velocity

and t is the time taken

We know that the slope of the v - t graph gives the acceleration of an object.

So, it can be seen that from 6 to 8 seconds, Elan accelerated faster than Anna as the slope for Elan is more.

So, the correct option is (c) " From 6 to 8 seconds, Elan accelerated faster than Anna ".

Texture and composition are different because they are not the same aspect. texture has to do with feel and so on, where as composition is the chemical makeup which you cant touch like you can texture.

Answer from: Quest

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
