Answer:
solid, liquid, gas
Explanation:
The three phases of water are the three states of matter water can be found in, and that is:
solid (as in ice)
liquid (as in water)
gas (as in water vapor)
Answer:
50.4÷1.18= 42.7m/s as speed is equal to the distance over the time taken
When you jumó ur legs put force on ground
Surface tension is the direct measure of the cohesive forces between liquid molecules that allows them to form "film", making it more difficult to move an object through the liquid surface. Compared to other known liqiuds, the surface tension of water is much greater.
Explanation:
It is given that,
Initial height of the ball, 
As it stops, its position, x = 0
It is in contact with the ground for 19.0 ms before stopping, 
Initial speed of the ball, u = 0
(a) Let a is the acceleration of the ball during the time it is in contact with the ground. Its can be calculated suing equation of kinematics as :

a =-g


v = 18.25 m/s
(b) The average acceleration can be calculated as :



As the value of acceleration is positive, so the ball is accelerating in upward direction.
