Explanation:
It is given that,
Length of rod, l = 14 cm = 0.14 m
Total charge,
We need to find the magnitude and direction of the net electric field produced by the charged rod at a point 36.0 cm to the right of its center along the axis of the rod, z = 36 cm = 0.36 m
Electric field at the axis of rod is given by :
Where
is the linear charge density,
So,
E = −7849988.22 N/C
or
Negative sign shows the direction of electric field is inward in all direction. Hence, this is the required solution.

The diagram that represents rays from the sun is given below.
The answer from the diagram is parallel lines.

The formula for this is n_i * Sin(i) = n_r * sin(r)
n1 = 1.333 water
n2 = 1.309 ice
i (angle) = 40o
r (angle) = ?
Solution
1.333 * sin(40) = 1.309*sin(r)
1.333 * sin(40)/1.309 = sin(r)
0.6546 = sin(r)
sin-1(0.6546) = 40.88 degrees.
I guess my closest answer would be A. I'm not rounding at all and that's the answer I get.
