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:
At the end of scene 1, Anne and Peter relationship changes them from being acquaintances to close friends and from the side of Anne, it is a little more than that.

Answer:
Diffusion expends no energy. Rather the different concentrations of materials in different areas are a form of potential energy, and diffusion is the dissipation of that potential energy as materials move down their concentration gradients, from high to low.

<span>The sodium in sodium bicarbonate increases the sodium concentration in the blood stream. Through osmosis, larger amounts of water enters the blood stream, thereby increasing the person's blood pressure. For persons with already high blood pressure, this can prove to be dangerous.</span>
