Aim of the experiment :To test between Shampoo A and Shampoo B and to find out which shampoo is more effective in making my hair look shinier.

Procedure,  On day 1, I would apply Shampoo A on my dirty hair. Leave it on my hair for 5 minutes then wash it off with cold water.

Observation and Data Collection: After my hair is dry I would observe it under natural light and also take a picture of my hair so that I have record keeping of the shiny luster of the hair.

On day 2, I would repeat the same steps with Shampoo B.

Analysis: At the end of day two I would then compare the pictures of my hair to determine which shampoo between A and B was more effective in giving my hair a shiny luster.

Vein deposits are usually produced by _____. weathering density sorting hydrothermal solutions cementation
mart [117]

Answer:

Hydrothermal solutions

Explanation:

Vein deposits which cuts through rock layers are usually products of hydrothermal solutions.

Veins are rich ore deposits in which superheated water rich in dissolved minerals penetrated through a rock body and the minerals becomes precipitated and deposited in the process. Most veins have small width and a great length. Some occurs as veinlets depending on the nature of the weaknesses they trace out in a rock body.

Veins contains minerals such as gold, copper ore, rare earth metals. Most hydrothermal solutions contains minerals that are not compatible with the melt as rocks crystallize. They preferred to be carried with super heated water which deposits them seperately.

ElenaW [278]

Explanation:

Wind turbines generate electricity by following simple principle. Moving wind transfers energy to the to the blades of the wind mill which results in spinning of the blades. These blades are connected to internal shaft which also starts spinning. This spinning of shaft generates electricity which is further distributed to electrical substations to provide electricity to homes and businesses.

Step 1: Wind moves the blades of the turbine.

Step 2: Internal shaft spins

Step 3: Generator produces electricity

Step 4: Distribution lines carry electricity to substation

A 19.0 L helium tank is pressurized to 26.0 atm. When connected to this tank, a balloon will inflate because the pressure inside
vesna_86 [32]

Answer:

The new volume of the balloon when the pressure equalised with the pressure of the atmosphere = 494 L.

The balloon expands by am additional 475 L.

Explanation:

Assuming Helium behaves like an ideal gas and temperature is constant.

According to Boyle's law for ideal gases, at constant temperature,

P₁V₁ = P₂V₂

P₁ = 26 atm

V₁ = 19.0 L

P₂ = 1 atm (the balloon is said to expand till the pressure matches the pressure of the atmpsphere; and the pressure of the atmosphere is 1 atm)

V₂ = ?

P₁V₁ = P₂V₂

(26 × 19) = 1 × V₂

V₂ = 494 L (it is assumed the balloon never bursts)

The new volume of the balloon when the pressure equalised with the pressure of the atmosphere = 494 L.

The balloon expands by am additional 475 L.

Hope this Helps!!!
