Answer:
The acceleration of the box across the floor is 7.0588 
Explanation:
Given:
Mass of the box = 2550 gram
net force acting on the box = 18 .0 N.
To Find:
The acceleration of the box across the floor = ?
Solution:
Newton's 2nd Law of Motion states that the acceleration of an object as produced by a net force is "directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
"
Newton's Second Law formula is
F = m a
Where:
F = the magnitude of the net force, in N
m = the mass of the object, in Kilogram
a = the acceleration of the object, in 
Now substituting the values, we get
18.0 = a (2.55) [since 2550 gram = 2.55 kg]

a = 7.0588

Answer: Un ejemplo de ecosistema es un estanque. Todos los seres vivos del estanque (ranas, peces, bacterias, plantas acuáticas, etc.) se consideran factores bióticos. Los factores abióticos del ecosistema del estanque incluirían todos los factores no vivos (agua, luz, oxígeno disuelto, nitratos, etc.) que se encuentran en el estanque. Un bioma es una colección de ecosistemas diferentes que comparten condiciones climáticas similares. El noreste de Minnesota es un bioma de bosque de coníferas. En esta región del estado de Minnesota encontrará ecosistemas de estanques, bosques, ríos y arroyos, etc.
