Licemer1 [7]3 years ago

<u>Answer:</u> because air has mass.

<u>Reasoning:</u> The Atmosphere has little to do with the concept here.

Wind moving air, why would that resulting in pressure? Does wind push you aside make you exert pressure?

Though increased temperatures can increase pressure. It doesn't affect it fully.

the correct answer is the first one because air has mass.

when gases molecules hit a surface or wall or in a room, they exert forces on how much particles or how hard their hitting that surface. so the more wild (hot) the molecules are the more pressure there is.

An atom of sodium-23 (Na-23) has a net charge of
maksim [4K]

Answer:

Protons= 11

neutrons= 12

electrons = 10

Explanantion:

Look for Na on periodic table

Atomic Number = 11

Atomic Mass = 23 (round it to be an integer)

Number of protons = Atomic number = 11

Number of neutrons = Atomic mass - atomic number = 23-11 =12

Number of electrons = 11 - e = ´+1 , electrons = 10

4. ¿Cuál es la resistencia de un alambre de
Artemon [7]

Answer:

R=0.0438 Ω

Explicación:

1) Hallar el área o sección del conductor de cobre, usando esta fórmula:

                                      A=π.r² (Pi x radio al cuadrado)

Debido a que conocemos el diámetro (1.5mm) su radio es la mitad de esto es decir 0.75mm, y lo sustituimos en la fórmula:

                                      A=π.(0.75mm)²

                                      A=π(0.5625mm²)

                                      A=1.7671mm²

2) La resistividad del cobre es: rho = 0,0172 y la incluimos en la fórmula siguiente:

                                      R=p  

                                      R=0,0172Ω  x  

Simplificamos:

R=

El resultado es:

R=0.0438 Ω
