A science teacher gives a student four beakers, each with a different liquid inside. The table provided shows the volume of each

liquid. Students will need to measure the mass of each liquid in order to calculate the density. When the student mixes all four liquids into one beaker, each liquid separates into a different layer. Using the volume and mass, students will calculate the density of each liquid and list them in order from least dense to most dense. What is the outcome variable (dependent variable) in this experiment? Please Hurry i have until midnight of today! Thank youu so much

The concept of density allows finding the density and ordering the liquids from lowest to highest they are:

  •  dishwashing liquid < vegetable oil < water < corn syrup
  • The dependent variable of the experiment is the mass of each body.

Density is the relationship between mas and volume, it is one of the most used relationships in liquids,

            \rho = \frac{m}{V}

where ρ is the density, m the mass and V the volume

Systems of units are systems of measurements where fundamental units are defined by convention and are used to be able to exchange measurements with precision and accuracy. The most widely used system today is the international measurement system (SI), let's reduce the magnitudes to this system

We use that one milliliter of water is equal to 1 cm³ of water

                    V = 10 cm³ ( \frac{1m}{100 cm} )² = 10 10⁻⁶ m³

In this exercise they give that the volume for all the liquids are equal, the mass is a measure in a triple beam balance whose appreciation is 0.1 g = 0.1 10⁻³ kg, in the following table we find the reading of the mass for each substance

Material         Mass (10⁻³ kg)      Density (kg / m³)

Dish soap           9.1                           910

Vegetable oil     9.5                          950

Water                  9.97                        997

Corn syrup        14.2                         1420

We calculate the density

Liquid dishwasher

                       \rho = \frac{9.1 \ 10^{-3} }{10 \ 10^{-6}}

                       ρ = 910 kg / m³

The other values ​​are calculated in the same way and it is in the last column of the table

The independent variable in an experiment is the one that the researcher controls, in this case the volume of each sample and the dependent variable is the one that the researcher measures in this case the mass of each material.

In conclusion, using the concept of density, we can order the liquids by their density from lowest to highest they are:

  • Dishwashing liquid < Vegetable oil < Water < Corn syrup
  • The dependent variable of the experiment is the mass of each body.

The dependent variable in this experiment is the mass of each liquid.

Density is the ratio of mass to volume of a substance. In this experiment, since the volume of each liquid is given, to get density, mass of each quantity must be known which is the outcome.

Density also depend on the mass of a substance and density can easily be identified by mass if all the substance in question have the same volume.

In this experiment, all the liquid have the same volume. Since the student want to list them in order from the least dense to the most dense, how dense the liquid are will be a function of the differences in liquid mass.

The least dense liquid will float. That is, will be at the top most of the container. While the most dense will be at the bottom of the container.

Therefore, the dependent variable in this experiment is the mass of each liquid

For a star with a parallax angle of 1/2 of an at arcsecond, what will be its distance in parsec?
avanturin [10]

(1 parsec) is the distance at which an object has a parallax of 1 arcsecond. The distance is about 3.26 light years.

Another way to understand it is:  The distance from which the Earth's orbit appears 1 arcsecond across.

For a parallax angle of 1/2 arcsecond, the distance is <em>2 parsecs </em>(about 6.52 light years).

1 arcsecond is 1/3600 of a degree, 0.00028 degree.

Bryce, a mouse lover, keeps his four pet mice in a roomy cage, where they spend much of their spare time–when they\'re not sleep
Anit [1.1K]

Answer:

mice total momentum (-0.000250, 0.00639) Kg m

Explanation:

To calculate the moment of the mice we must multiply their mass by their velocities, remember that the moment is a vector quantity, so we use the components of velocity

mouse 1

  m1 = 0.0225 Kg

  V1 = (0.869, -0.283) m / s

 

  Px = m Vx

  Px1 = 0.0225 0.869

  Px1 = 0.01955 Kg m

  Py = m Vy

  Py1 = 0.0225 (-0.283)

  Py1 = -0.006368 Kg m

  P1 = (0.0196, -0.00637) Kg m

Mouse 2

 m2 = 0.0223 Kg

 Px2 = 0.0223 (-0.883) = -0.0196 Kg m

 Py2 = 0.0223 (-0.253) = -0.00564 Kg m

 P2 = (-0.0196, -0.00564) Kg m

Mouse 3

 m3 = 0.0197

 Px3 = 0.0197 0.345 = 0.00680 Kg m

 Py3 = 0.0197 0.803 = 0.0158 Kg m

 P3 = (0.00680, 0.0158) Kg m

Mouse4

  m4 = 0.0127 Kg

  Px4 = 0.0127 (-0.555) = -0.00705 Kg m

  Py4 = 0.0127 0.205 = 0.00260 Kg m

  P4 = (-0.00705, 0.00260) Kg m

To find the total momentum we must add each component of the individual moments

   Px = Px1 + Px2 + Px3 + Px4  

   Py = py1 + Py2 + Py3 + Py4

   Px = 0.0196 -0.0196 +0.00680 -0.00705

   Px = -0,000250 Kg m

   Py = -0.00637 -0.00564 +0.0158 +0.00260

   Py = 0.00639 Kg m

   P = (-0.000250, 0.00639) Kg m

Which part of earths surface has the greatest rotational speed
Anni [7]
Every point on the surface must have the same rotational speed.
Otherwise some places would rotate away from other places.

If the next block of your city rotated faster than the block that you live on,
then you could sit at home, look out the window, and watch your school
rotate past your house.

The map of the continents on the Earth would change constantly.

You are stranded in a blizzard. You need water to drink to drink,and you're trying to stay warm.should the melt the snow and dri
Crazy boy [7]
It would be a really bad idea to eat the snow because you obviously are trying to stay warm right? Well, the best thing to do is melt the snow. However, the process of melting the snow would have a few complications as well. But yes, the latter idea (drinking the snow) is a better idea (not the best).
