Answer:

Neither energy nor matter

Explanation:

A system is defined as the part of the universe. In thermodynamics, systems are of three types i.e.

1. Open System : In an open system, both energy and matter can freely exchange with surrounding. For example- boiling water in an open pan transfers both energy and matter.

2. Closed system : In a closed system, only energy is exchanged with the surrounding. For example- boiling water with a lid on the pan exchanges only energy with the surrounding.

3. Isolated system : In an isolated system, neither energy nor matter exchanges with the surrounding. For example : a thermos flask does not exchange energy and matter with the surrounding.

Hence, the correct option is (a) " neither energy nor matter ".

Recall that if a line is parallel to the vector v and passes through the point P0, which is the tip of the position vector r0, t
Elenna [48]

Answer:

The vector equation of the line is

                                \overrightarrow{r}=+t

Parametric equations for given line are

                                       x=7+t\\y=-8+6t\\z=3-13t

Explanation:

The vector equation of the line is given by

                                     r(t) = r_{o} + tv

r₀ = (7, -8, 3)

v = (1, 6, -13)

At these points the vector equation for this line is:

\overrightarrow{r}=\overrightarrow{r_{o}}+t\overrightarrow{v}\\\overrightarrow{r}=+t

Parametric equations for given line are

                                       x=7+t\\y=-8+6t\\z=3-13t
