Answer:
The acceleration of the ball is constant and equal to -9.81 m/s² (acting downwards)
The velocity of the ball reduces at a constant rate with time on its way up
Explanation:
The motion of the ball upwards is described by the following equation;
v = u - g × t
v² = u² - 2 × g × s
Where;
v = The final velocity of the ball
u = The initial velocity of the ball
g = The acceleration due to gravity = Constant
s = The height of the bass after a given time, t
t = The time in which the ball is rising
Therefore, the acceleration of the ball = The acceleration due to gravity (Constant) = -9.81 m/s²↓
From v = u - g × t = u - 9.81 × t , the velocity of the ball reduces at a constant rate with time on its way up.
Surface wave is defined as the type of wave that is capable of moving at the interface between two different types of mediums/materials (example is surface wave that is between the water and air).
Particles in the surface wave usually move in orbital or elliptical shapes and their motion is a combination of both longitudinal and transverse motions.
Based on the above, the correct choice is:

Answer:
Explanation:
Sun - - - - - Earth----Capital building----Human----Atom
The sun would exert more gravitational force because it is the massive.
Gravitational force is directly proportional to mass.
