Answer:
1 ) Distribution of mass within the ball
2 ) Height of the ramp
Explanation:
Acceleration of a rolling body down an inclined plane is given by the following formula
a = g sinθ / ( 1 + k² / R² )
k is radius of gyration , R is radius of the spherical object ,
when acceleration is more , velocity will also be more .
for objects in which masses are lying in the periphery like in hollow sphere , the value of k²/R² will be high so denominator of the expression will be high so acceleration will be less , hence velocity on reaching the bottom will be less.
On mass of the ball , velocity will not depend .
If height is increased , ball will have acceleration for greater time so velocity will be high.
On radius it will not depend because , radius r and k increases proportionately.
Answer:
Wave height is the vertical distance between the crest (peak) and the trough of a wave. Some other definitions: Still-Water Line is the level of the lake surface if it were perfectly calm and flat. Crest is the highest point on the wave above the still-water line.

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.
