C, I believe. If it doesn't travel any distance, then it's speed should be zero, unless it is trying to travel against a conveyor or something.

1. What is the name for rise of deeper water to the surface?
Vikentia [17]

Upwelling

Explanation:

The rise of deeper water to the surface is called upwelling.

Upwelling is a term used in oceanography to describe the rise of cold and denser water to the surface.

  • This occurs usually along the short where wave action is very prevalent.
  • Surface wave pushes away warm water.
  • Then deeper nutrient-rich cold water rises due to low density and volume of water on top.
  • This nutrient rich water supports biological activities because they are rich.
  • Wind along the coast can also force surface water down.

Group-8 elements are inert and possess
Artemon [7]

Answer:

Group 8 elements are inert and possess :

1. Low Boiling Points

2. High ionization energies

3. Electronegativities is very low

4. No color, odor

Explanation:

Group 8 elements are also called as Noble Gases. They are unreactive.

They have low boiling points means they remains monoatomic  at room temperature.  Having high ionization energy means that it is very difficult to remove an electron from its valence shell.

A home remodeling company charges $10 per square yard for installing new carpets. What is the cost for installing a carpet for a
balu736 [363]

Answer:

$200.0 is the cost for installing a carpet for a room that measures 12.0 feet by 15.0 feet.

Explanation:

Length of the room = l = 15.0 ft = \frac{15.0}{3} yard=5.0 yard

Width of the room = w = 12.0 ft = \frac{12.0}{3} yard=4.0 yard

(1 yard = 3 feet)

Area of the room = l × w = 4.0 yard\times 5.0 yard = 20.0 yard^2

Cost for installing a carpet for a room = $10 per square yard

Cost for installing a carpet for a room wit area 20.0 square yard :

20.0 yard^2\times $10/ yard^2=$200.0

$200.0 is the cost for installing a carpet for a room that measures 12.0 feet by 15.0 feet.

Determine the concentration of a solution made by dissolving 1.40grams NaCL in enough water to make 30.0mL of solution.
KiRa [710]

Answer: 0.8M

Explanation:

Given that,

Amount of moles of NaCl (n) = ?

Mass of NaCl in grams = 1.40 g

For molar mass of NaCl, use the molar masses:

Sodium, Na = 23g;

Chlorine, Cl = 35.5g

NaCl = (23g + 35.5g)

= 58.5g/mol

Since, amount of moles = mass in grams / molar mass

n = 1.40g / 58.5g/mol

n = 0.024 mole

Now, given that:

Amount of moles of NaCl (n) = 0.024

Volume of NaCl solution (v) = 30.0mL

[Convert 30.0mL to liters

If 1000 mL = 1L

30.0mL = 30.0/1000 = 0.03L]

Concentration of NaCl solution (c) = ?

Since concentration (c) is obtained by dividing the amount of solute dissolved by the volume of solvent, hence

c = n / v

c = 0.024 mole / 0.03 L

c = 0.8 M (0.8M means concentration is in moles per litres)

Thus, the concentration of the solution is 0.8M
