Answer:
can you explain more or..,.
Explanation:
Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides. Hence, the range is much larger in a spring tide than in a low tide.
The difference between the observed points and the regression line points is equal to the correlation.
The strength and direction of a relationship between two or more variables are described by the statistical measure of correlation, which is given as a number. However, a correlation between two variables does not necessarily imply that a change in one variable is the reason for a change in the values of the other.
Regression expresses the relationship as an equation, whereas correlation assesses the strength of the linear link between two variables. The square of the correlation coefficient, also known as Pearson's r, between the observed and predicted values in a regression is sometimes referred to as R2.

Part a)
Here in this we can use momentum conservation as there is no external force on it

here we know that





now by above equation



Part b)
Final kinetic energy of the system



Initial Kinetic energy of the system will be



So here kinetic energy is decreased for this system
final energy is less than initial energy
