Answer:
we approach a maximum or minimum the values of the ordinate are closer and closer and when passing this point the values change their trend
Explanation:
The reason for this process occurs because as we approach a maximum or minimum the values of the ordinate are closer and closer and when passing this point the values change their trend if they were rising, they begin to fall and if they were falling they begin to rise. Therefore the maximum point is a point of inflection of the curve since its trend changes.
Another way of looking at this process is that mathematically the point where there is a maximum or a minimum corresponds to the point where the first derivative is equal to zero, this is the slope of the line is horizontal, so the points before after correspond to values with slope of different sign.
THe best answer would be observation because you can see that all 3 are made up of water which you don't need to infer because you have the proof when you look at all 3 different types of precipitation.
I hope this helps you out.
<span>F= ma force is directed on the working surface so 40 = m x 2 hence
m must be 20 units needed are probably kg</span>
The distance from mile-mark 10 to mile-mark 115 is (115-10) = 105 miles.
Speed = (distance covered) / (time to cover the distance) .
Speed = (105 miles) / (1.75 hours)
Speed = (105/1.75) (mi/hr)
<em>Speed = 60 mph</em> (B)
Based on the options given, the answer is two waves subtract from each other. Destructive interference happens when two waves meet each other however with different frequencies cancel each other out.
