There are seven fundamental units, out of which two examples of non-vector quantities could be:
1) meter (unit of length)
2) second (unit of time)
Hope this helps!
The correct answer is: acceleration.
In fact, the slope of the graph of velocity versus time corresponds to the ratio between the variation of v and the variation of t:

But this is exactly the definition of acceleration:

, so acceleration is the correct answer.
Answer:

Explanation:
From the question we are told that
Two points charge of 4\mu C and 2\mu C
Generally we find the Va and Vb individually to find there difference
Given a rectangle with two equal sides each,Assume lengths for bot sides
Length L=0.3
Breath B=0.4
Diagonal D=
at opposite sides
Mathematically Va can represented as





Mathematically Vb is represented as





Therefore

Answer:
because it is less dense than the surrounding air
