Answer:
8 V
Explanation:
There is no resistance between the left legs of voltmeters 2 and 3 and there is no resistance between the right legs of voltmeters 2 and 3. They are measuring the same voltage.
<span>Space.Energy can pass through the space only by radiation. In space there is no matter, liquids or solids to pass energy. The sunlight passes through space and reach earth and other planets in the form of radiation. Radiation is the transmission of energy in the form of electromagnetic waves which needs no medium.</span>

Answer:
the compass direction of the resultant displacement is
south of west
Explanation:
Generally using cosine we can obtain the resultant R as follows

=> 
=> 
We can obtain the direction of the resultant by first using sine rule to obtain angle C as follows

=> ![C= sin ^{-1} [\frac{A * (sin 70)}{R} ]](https://tex.z-dn.net/?f=C%3D%20%20sin%20%5E%7B-1%7D%20%5B%5Cfrac%7BA%20%2A%20%20%28sin%2070%29%7D%7BR%7D%20%5D)
=> ![C = sin ^{-1} [\frac{20 * (sin 70)}{19.48} ]](https://tex.z-dn.net/?f=C%20%3D%20%20sin%20%5E%7B-1%7D%20%5B%5Cfrac%7B20%20%2A%20%20%28sin%2070%29%7D%7B19.48%7D%20%5D)
=> 
Then the direction is obtained as

=> 
=> 
Hence the compass direction of the resultant displacement is
south of west
Answer:
A = 4.49
α = 57.72°
Explanation:
Knowing the magnitude of x & y of a vector we can determine the total magnitude of a vector.

The angle tangent can be used to determine the angle.

Answer.
The road on the hills goes upward with the increasing length of the road.That's why we make a winding roads because it reduces the allover surface inclination in every portion of the road which is suitable for driving the vehicles.
