Hey there!
Your answer: shared electrons
There would usually be two forces that would make an atom stick together. It would be the positive, and negative of a electric charge. All this coming together would be the electromagnetic force. This is liked we talked about, both positive and negative charges attracted. And that would be the strong force. Which then gives our answer to be electrons.

6. gradation
<u>Explanation</u>
1. An indication of how close a measurement is to the correct result is called precision.
2. The mass of a substance per unit volume is called density of a substance.
3. A quantity in an experiment that remains unchanged or constant is called a control group.
4. Anything that has mass and occupies space is called matter.
5. The degree to which a measurement can be replicated is called accuracy.

Answer:
1. 98 N
2. 51.0 m
Explanation:
masa 25 kg
velocidad 20 m/s
coeficiente de rozamiento .4
<u>Fuerza de rozamiento:</u>
mu * N, where mu = coeficiente de rozamiento, N = fuerza normal
Calcula N:
F = ma = 25 * -9.8 = -245 N
F rozamiento = mu * N = .4 * -245 = -98 N
<u>Espacio que recorrerá:</u>
F rozamiento = ma
-98 = 25a
a = -3.92 de-aceleración de la fuerza
vf = 0 m/s
vf = at + vi
0 = -3.92t + 20
t = 5.10 seg
x = 1/2 at^2 + vi*t
= 1/2 * -3.92 * 5.10^2 + 20*5.10
= 51.0 m
