Answer:
Explanation:
The total distance is how far you walk from the starting point.
Distance through west = 18.0m
Distance through north = 25.0m
Total distance covered = 18.0+25.0m
Total distance covered = 43.0m
This means that I am 43.0m from the starting point
Displacement is the distance covered in a specified direction. The displacement will be gotten using the Pythagoras theorem as shown:
The direction of your displacement is 30.81m
Direction is gotten according to the formula;
<em>Note that the direction to the west is negative, that is why the x is -18.0m</em>

Answer:
4370.83044 m²
Explanation:
= Net work done = 570 kW
= Low temperature resrvoir = 20 °C
A = Area of solar collector
Amount of solar heat received = = 0.315A
The theoretical minimum solar collector area required is 4370.83044 m²
