Answer:

The contracting nebula flattens into a disk with a bulge at the center.

Explanation:

Sun was formed in solar nebula about 4.5 billion years ago. Solar nebula is a molecular cloud of dust and gases which slowly spun and collapsed due to condensation of gases. The cloud started spinning faster and collapsed. Thereafter, the contracted nebula flattened into a disk and bulge at the center was formed. The temperature and pressure rose till the nuclear fusion reaction started releasing huge amount of energy. The sun was born. The rest of the matter accreted to form planets.

10. Which would make the best aquifer?

Levart [38]

c. sandstone in the zone of saturation

Explanation:

The best aquifer of all is a sandstone in the zone of saturation. An aquifer is a porous and permeable formation where groundwater can accumulate.

To be a good aquifer, a rock or soil must be porous and permeable.
Porosity is the amount of void spaces present in a rock.
Permeability is the inter-connectivity of the pore spaces.

The zone of saturation is the zone below the water table where water is always present underground.

Sandstones have high porosity and permeability.
They are good aquifers when found at the zone of saturation.

What is the volume, in milliliters, occupied by 30.07 g of an object of density equal to

den301095 [7]

Answer:

$\boxed {\tt 20.317567567568 \ mL}$

Explanation:

The density formula is:

$d=\frac{m}{v}$

Let's rearrange the formula for $v$ . the volume. Multiply both sides by $v$ , then divide by $d$ .

$d*v=\frac{m}{v}*v$

$d*v=m$

$\frac{d*v}{d}=\frac{m}{d}$

$v=\frac{m}{d}$

The volume can be found by dividing the mass by the density. The mass of the object is 30.07 grams and the density is 1.48 grams per milliliter.

$m= 30.07 \ g\\d= 1.48 \ g/mL$

$v=\frac{30.07 \ g}{1.48 \ g/mL}$

Divide. Note, when dividing, the grams, or $g$ will cancel out.

$v= \frac{30.07}{1.48 \ mL}$

$v=20.317567567568 \ mL$

The volume of the object is 20.317567567568 milliliters.
