I don’t really understand the question but if you are asking if matter can be found in different states of matter then yes
DescriptionEcosystem services are the many and varied benefits to humans gifted by the natural environment and from healthy ecosystems. Such ecosystems include, for example, agroecosystems, forest ecosystems, grassland ecosystems and aquatic ecosystems.
Answer:
<em>The terminal velocity at sea level is 7.99 m/s</em>
<em>The terminal velocity at an altitude of 5000 m is 10.298 m/s </em>
<em></em>
Explanation:
mass of sphere m = 10 kg
radius of sphere r = 0.5 m
air density at sea level p = 1.22 kg/m^3
drag coefficient Cd = 0.8
terminal velocity = ?
Area of the sphere A = = 4 x 3.142 x = 3.142 m^2
terminal velocity is gotten from the relationship
where g = acceleration due to gravity = 9.81 m/s^2
imputing values into the equation
= <em>7.99 m/s</em>
<em></em>
If at an altitude of 5000 m where air density = 0.736 kg/m^3, then we replace value of air density in the relationship as 0.736 kg/m^3
= <em>10.298 m/s </em>

Answer:
Newtons 3rd law
Explanation:
Newtons third law states; for every action, there is an equal but opposite reaction force.
The action force in this case in the foot kicking the soccer ball, but the reaction force is the ball 'kicking' back on the foot. This reaction force has the same magnitude as the action force, but opposite in direction, which is why the foot is left stinging.
