Answer:

La masa del aire contenido en la habitacion es 65000 gramos.

Explanation:

La densidad se define como la propiedad que tiene la materia, ya sean sólidos, líquidos o gases, para comprimirse en un espacio determinado. En otras palabras, la densidad es una magnitud que permite medir la cantidad de masa que hay en determinado volumen de una sustancia. Entonces, la expresión para el cálculo de la densidad es el cociente entre la masa de un cuerpo y el volumen que ocupa:

d=\frac{m}{V}

En este caso:

  • d= 0,0013 \frac{g}{cm^{3} }
  • m=?
  • V= 4 m*5 m*2,5 m= 50 m³= 50.000.000 cm³ (siendo 1 m³=1.000.000 cm³)

Reemplazando:

0,0013\frac{g}{cm^{3} }=\frac{m}{50000000 cm^{3} }

Resolviendo obtienes:

m= 0,0013 \frac{g}{cm^{3} } * 50.000.000 cm³

m=65000 g

<u><em>La masa del aire contenido en la habitacion es 65000 gramos.</em></u>

can a light object that was hit with a small force accelerate as rapidly as a heavier object hit with a big force? why or why no
Tcecarenko [31]

The acceleration is defined by force divided by the mass of the object. So, When the smaller object is hit by a small force, it can produce equal acceleration which is same as that of the bigger body hit with large force.

<h3><u>Explanation:</u></h3>

Force is defined as the product of the mass of the body its applied to and the acceleration of the body in the direction of the force. So acceleration is force divided by the mass of the body.

Let the mass of the smaller body be m and that of the larger body be M.

The smaller force applied on the smaller body be f and the larger force applied on the larger body be F.

So acceleration of the larger body = F/M.

Acceleration of the smaller body = f/m.

For the accelerations to be same,

F/M = f/m.

Or F/f = M/m.

So when the ratio of the force applied on two bodies is in ratio of their masses, the acceleration becomes equal.

Which of the following best explains how the results of Rutherford’s experiment affected Thomson’s widely-accepted atomic model?
hichkok12 [17]

Explanation:

Thomson's suggested the plum pudding model of the atom in which the atomic space is made up of electrons surround by positive charges.

Rutherford in his gold foil experiment revised the plum pudding model of the atom;

  • He discovered that most of the alpha particles passed through the foil while a few of them were deflected back.
  • To explain this observation, he suggested the atomic model of the atom.
  • In this model, an atom is made up of a small positively charged center where nearly all the mass is concentrated.
  • Surrounding the nucleus is the extranuclear part made up of electrons.

How many grams of sodium are needed to produce 12.5g of sodium oxide
Hatshy [7]

Answer:

25 possibly

Explanation:

I'm not too sure about this, but sodium oxide is Na2O, 2 sodium and 1 oxygen, so 12.5g * 2 is 25

If someone else comes up with a more convincing argument listen to them
