Initially when ball is thrown up in air, its kinetic energy goes on decreasing. This loss in kinetic energy changes in potential energy and it keeps on increasing. This potential energy becomes maximum at highest point of its motion. At this highest point, kinetic energy of ball becomes zero. Now while coming down, potential energy goes on decreasing and this loss changes into kinetic energy. This kinetic energy keeps on increasing till it hits the ground or stopped by some external agent. Hope it helps.
Answer:
Increase
As the mass of either object increases, the force of gravitational attraction between them also increases.
Explanation:
The gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force.
As the mass of either object increases, the force of gravitational attraction between them also increases.

At the initial state: v1 = vf = 0.001053 m

/kg, h1 = hf = 467.11 kJ/kg, and s1 = sf = 1.4336 kJ/kgK.
The mass of the water is: m = V/v1 = 0.005/0.001053 = 4.7483 kg.
To find the final state, we will use the First Law:
Q12 = m(h2 - h1) for closed system undergoing a constant pressure process.
h2 = 1Q2/m + h1 = 2200/4.7483 + 467.11 = 930.43 kJ/kg.
At P2 = P1 = 150 kPa, this is a saturated mixture.
hf = 467.11 kJ/kg, hfg = 2226.5 kJ/kg, sf = 1.4336 kJ/kgK, and sfg = 5.7897 kJ/kgK
s2 = sf + sfg (h2 – hf )/hfg = 1.4336 + 5.7897(930.43 – 467.11)/2226.5 = 2.6384 kJ/kgK.
The entropy change of water is:
Delta Ssys= m(s2 – s1) = 4.7483(2.6384 – 1.4336) = 5.72 kJ/K.
If Voq doubles, abN gets multiplied by 16 .
If Voq=3, abN=81 .
Answer:
The maximum mass is 
Explanation:
The wavelength of the electron can be determined by means of the De Broglie equation.
(1)
Where h is the Planck's constant and p is the momentum.
(2)
Where m is the mass and v is the velocity.
Before using equation 2 it is necessary to express the wavelength from femtometers to meters.
-- 
Finally, equation 2 can be used.
But 
Hence, the maximum mass is
