<span>The amount of solar energy available varies by location on earth, the time of the day at that location, the season and weather conditions. Rain, fog, and clouds will lower the amount of solar power available to gather and there are fewer hours of sun available in different seasons (winter for North America). To gather solar power, you also need a large area. This can be lessened by conditions such as snow, so that even on a sunny day, covered panels will collect less energy.</span>
Answer:
39)
a) distance traveled = 1 mile
b) displacement = 0 mile
40) - 4 (m/s)
41-) distance traveled = 5 [m]
displacement = 3.6 [m]
Explanation:
The distance differs from the displacement, the distance traveled is equal to the sum of all displacements made by the particle or object.
Displacement is the difference between the initial point and the final point where the object or particle was stopped.
Then we can use the equation given:
![a=\frac{(v_{f} - v_{i} )}{t} \\where:\\v_{f}=16[m/s]\\v_{i}=2[m/s]\\t=3.5[s]\\a=\frac{(2-16)}{3.5}\\ a=-4[m/s]](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B%28v_%7Bf%7D%20-%20v_%7Bi%7D%20%29%7D%7Bt%7D%20%5C%5Cwhere%3A%5C%5Cv_%7Bf%7D%3D16%5Bm%2Fs%5D%5C%5Cv_%7Bi%7D%3D2%5Bm%2Fs%5D%5C%5Ct%3D3.5%5Bs%5D%5C%5Ca%3D%5Cfrac%7B%282-16%29%7D%7B3.5%7D%5C%5C%20a%3D-4%5Bm%2Fs%5D)
The minus sign means the particle is slowing down.
For the 41) we can see the attached image.
In the graph we can see that the particle moves north 3 miles, so that the first distance is 3 miles, then moves 2 miles east being the second distance of 2 miles. Thus the sum of the distances is 3 + 2 = 5 miles.
Displacement is the difference between the endpoint and the initial point since the form of displacement is a straight line, we can use the formula of the straight line or the theorem of Pythagoras.
