Answer:
v = 4.03 m/s
Explanation:
It is given that,
Distance covered by a lizard, d = 2.1 m
Time taken by lizard, t = 0.52 s
We need to find the average speed of the lizard. The distance covered divided by time taken is called the average speed of lizard. So,

So, the average speed of the lizard is 4.03 m/s.
Answer:
Explanation:
Using Coulomb's Law we know that the electric field E at point
is:

where
is the Coulomb's Constant, q is the source charge, d is the distance between point and position of the source point charge, and
is the position of the source point charge.
Taking all this in consideration, the unit vector clearly is:

For our problem,
, as the charge is located at the origin.
So

and d will be the magnitude of 
Now, we can take the values for each point.
<h3>a.</h3>

and, the magnitude of the vector is



So, the unit vector is:



<h3>b.</h3>

and, the magnitude of the vector is



So, the unit vector is:



<h3>c.</h3>

and, the magnitude of the vector is



So, the unit vector is:
