Answer:

Clouds of gas and dust as well as new star formation are typically seen in Spiral galaxy

Explanation:

The ingredients for star formation are gas and dust, a spiral galaxy is a group of stars that are together as a consequence of the gravitational pull between them and, as the name said it, has a spiral shape.

They are composed for a central bulge, a disk (in which a spiral arms structure can be seen), gas and dust. Because of the presence of gas and dust, star formation is possible.

What is the number “4” in SiCl4? a subscript a coefficient a product a reactant

Svetlanka [38]

Answer: 4 is the subscript in $SiCl_{4}$ .

Explanation:

We know that,

Subscript: The number of atom present in a given compound.

In $SiCl_{4}$ , 4 represents the number of chlorine atom in 1 mole of Silicon tetra chloride.

Coefficient: Number of atom which is used in reaction.

For example: In $3SiCl_{4}$ , 3 is the coefficient of silicon tetra chloride.

A Product : In the balance equation, right hand side is called product.

A reactant : In the balance equation, left hand side is called reactant.

For example: the balance equation is

$2Mg+O_{2}\rightarrow 2MgO$

In this equation, $2Mg+O_{2}$ is the reactants and $2MgO$ is products.

Hence, 4 is the subscript in $SiCl_{4}$ .

The speed of light is 3.0 x 108 m/s. How far does light travel in one day? Remember that you should first convert the day into s

Anna35 [415]

Answer:

$2.59\times 10^{13}\ m$

Explanation:

The speed of light is 3.0 x 10⁸ m/s

We need to find the distance traveled by it in one day.

1 day = 24 hours

1 day = 24 × 3600 seconds

= 86400 s

Now, using the formula of speed to find the distance covered as follows :

$d=v\times t$

Putting all the values, we get :

$d=3\times 10^8\ m/s\times 86400\ s\\\\d=2.59\times 10^{13}\ m$

Hence, light will cover $2.59\times 10^{13}\ m$ of distance in one day.
