#6). The tangent of an angle in a right triangle is
(opposite side) / (adjacent side) .
The side opposite the marked angle is 4cm.
The side adjacent to the marked angle is 12cm.
The tangent of the marked angle is (4cm / 12cm) = 1/3 .
The marked angle is the angle whose tangent is 1/3 .
You can find that online, or with your calculator, slide rule, Curta, or book.
#7). The cosine of an angle in a right triangle is
(adjacent side) / (hypotenuse) .
The side adjacent to the marked angle is 15m.
The hypotenuse is 19m.
The cosine of the marked angle is (15m / 19m) = about 0.78947...
The marked angle is the angle whose cosine is 0.78947... .
You can find that online, or with your calculator, slide rule, Curta, or book.
Well let's convert all these values out of standard form first:
2x10^-2 = 2x0.01 = 0.02m = 2cm
2x10^0m = 2x1 = 2m
2x10^-1m = 2x0.1 = 0.2m = 20cm
2x10^1m = 2x10 = 20m
Based on that, we know that 20cm is roughly equivalent to a basketball (at least it's closer than all the other values), so the answer is therefore 2 - 2x10^-1m
Answer:

Explanation:
That is correct what you did
Answer:
the electric potential at an infinite distance is the workdone in moving a charge from one point at an infinite distance to another point at an infinite distance. This will be zero.
Explanation:
Electric potential is given by
E= kQ/r²
If r becomes ∞, then
E= kQ/(∞)²= 0
So electric potential at an infinite distance away from the rod is zero
