When a fixed amount of ideal gas goes through an isochoric process:

zvonat [6]

Answer:

the gas does no work.

Explanation:

An isochoric process is a process in which the volume of a gas is kept constant.

The work done by a gas during a transformation is given by:

$W=p\Delta V$

where

p is the gas pressure

$\Delta V$ is the change in volume of the gas

For an isochoric process, the volume of the gas does not change, so

$\Delta V$

and so, according to the previous equation, the work done by the gas is zero:

W = 0

Ejercicio de la 2a ley de Newton

ICE Princess25 [194]

Answer:

Revisar las respuestas a cada problema, como se muestra mas adelante.

Explanation:

Para poder solucionar esta serie de problemas debemos de utilizar la segunda ley de Newton, la cual nos dice que la sumatoria de fuerzas sobre un cuerpo debe de ser igual producto de la masa por la aceleracion.

De esta manera tenemos:

ΣF = m*a

donde:

F = fuerza [N]

m = masa [kg]

a = aceleracion [m/s^2]

1 )

F = m*a

60 = m*4

m = 15[kg]

F = m*a

a = 250/50

a = 5 [m/s^2]

F = m*a

F = 80*2.5

F = 200 [N]

F = m*a

800 = 1500*a

a = 0.533[m/s^2]

F = m*a

100 = 500*a

a = 100/500

a = 0.2 [m/s^2]

What is the energy stored between 2 Carbon nuclei that are 1.00 nm apart from each other? HINT: Carbon nuclei have 6 protons and

Andrei [34K]

Answer:

$A. 8.29\times 10^{-18}\ J$

Explanation:

Given that:

p = magnitude of charge on a proton = $1.6\times 10^{-19}\ C$

k = Boltzmann constant = $9\times 10^{9}\ Nm^2/C^2$

r = distance between the two carbon nuclei = 1.00 nm = $1.00\times 10^{-9}\ m$

Since a carbon nucleus contains 6 protons.

So, charge on a carbon nucleus is $q = 6p=6\times 1.6\times 10^{-19}\ C=9.6\times 10^{-19}\ C$

We know that the electric potential energy between two charges q and Q separated by a distance r is given by:

$U = \dfrac{kQq}{r}$

So, the potential energy between the two nuclei of carbon is as below:

$U= \dfrac{kqq}{r}\\\Rightarrow U = \dfrac{kq^2}{r}\\\Rightarrow U = \dfrac{9\times10^9\times (9.6\times 10^{-19})^2}{1.0\times 10^{-9}}\\\Rightarrow U =8.29\times 10^{-18}\ J$

Hence, the energy stored between two nuclei of carbon is $8.29\times 10^{-18}\ J$ .
