Answer:
the rate of change in velocity per unit time is called acceleration
The height of the ball after the given time of motion is 3.275 m.
The given parameters;
- initial velocity of the ball, u = 4 m/s
- height of fall of the ball, h = 2.5 m
- time of motion, t = 0.5 s
The distance traveled by the ball is calculated as follows;
Thus, the height of the ball after the given time of motion is 3.275 m.

Cases A and B are all correct.
In Case C, the GPE is incorrect.
(But then, the power and HP have been correctly calculated
from the incorrect value of GPE, so we can't gig you too bad.)
2nd stone time = 13.0/9.8 = 1.33 seconds
distance = 0.5*9.8*1.33^2 = 8.67 meters
1st stone time = 1.33+1.5 = 2.83 seconds
distance = 0.5*9.8*2.83^2 = 39.24 meters
39.24-8.67 = 30.57 meters apart
Answer:
If there is a large difference between the concentration of one fluid and the concentration of the other, then the particles will diffuse faster. In the experiment, the dye particles in the food coloring are very concentrated.
