Que unidad de medida se utiliza para expresar la capacidad o volumen de un objeto? Da un ejemplo

Physics
1 answer:
galina1969 [7]2 years ago
5 0

Answer:

<em>Explicado a continuación</em>

Explanation:

Hay una pequeña diferencia conceptual entre la capacidad y el volumen de un objeto, a saber:

El volumen hace referencia al espacio que ocupa un objeto, mientras que la capacidad hace referencia al espacio que este contiene. Calcular el volumen de un cuerpo es medir cuánto ocupa mientras que calcular su capacidad es medir cuánto cabe en él.

En la práctica, ambos conceptos son usados indistintamente, ya que tienen unidades equivalentes.

El volumen tiene unidades de longitud al cubo, como por ejemplo:

m^3,\ cm^3\ ,dm^3,\ pie^3\ , pulg^3

y la capacidad se suele expresar en litros o unidades derivadas: litro, mililitro, centilitro, etc.

Como mencionamos, hay equivalencia engre los dos grupos de unidades. Entre las más conocidas están:

1\ lt=1\ dm^3,\ 1\ m^3=1000\ lt

At what distance is the electrostatic force between two protons equal to the weight of one proton?
bearhunter [10]

Answer:

The distance between two protons is 37 cm.                    

Explanation:

The electric force between two electric charges is given by :

F=k\dfrac{q_1q_2}{d^2}

Here,

k is the electrostatic force

d is the separation between charges

q_1\ and\ q_2 are charges

According to given condition, the electrostatic force between two protons equal to the weight of one proton. So,

W_p=\dfrac{kq^2}{d^2}

d=\sqrt{\dfrac{kq^2}{W_p}}

As protons are very small particle, W = m

d=\sqrt{\dfrac{kq^2}{m}}

d=\sqrt{\dfrac{9\times 10^9\times (1.6\times 10^{-19})^2}{(1.67\times 10^{-27})}}

d = 0.37 m

or

d = 37 cm

So, the distance between two protons is 37 cm. Hence, this is the required solution.

How is wave movement affected by the various mediums it may travel through?
Juliette [100K]

Answer:

speed is affected by the medium in wich the wave travels.

Explanation:

The speed of a wave is affected when traveling in different medium, depending on the medium in which the wave travels it can go faster or slower, or not even be able to travel in that medium.

For light waves, the denser the medium through which the wave travels, the slower it will go through it, as there is more resistance to the light particles.

And in waves like sound, which instead of particles is a vibration or disturbance in the medium, they travel faster in denser mediums such as metal, because the disturbance is transmitted more efficiently thanks to how close together that the particles are in the metal, This is why sound does not travel in a vacuum; there are not even particles to transmit the vibration.

According to Lenz's law, an induced current in the direction depicted in the picture would be created when: a. An external downw
LenKa [72]

Answer:

C. An external downward field is created or an external downward field is removed

Explanation:

As we can see that from the attached figure that the induced current would be counter clockwise. So the field occur because of induced current i.e. out of page. This represent that the current is induced in order to rise the flux out of the direction of the page

Therefore because of the external field, the field out of page & flux would be reducing or the external upward field is eliminated

So option C is correct
