A lab is done using different metals and the density of the metals are recorded in a data table. What is the independent variabl
vovikov84 [41]

Answer:   The independent variable is the type of metal being used.

{Note:  The "dependent variable" is the "measured density" that corresponds to each of the metals."}.

___________________________________________

Explanation:

___________________________________________

The "independent variable", which is plotted on the "x-axis" (horizontal axis), is the variable that can be "controlled/manipulated".  In this case, this would be the type of metal chosen.

The "dependent variable" , which is plotted on the "y-axis" (vertical axis) is the "obtained value/measurement/result" (that "cannot be controlled/manipulated").

In this case, the "density", which is the "measured value" that corresponds to the selected "meal", is the "dependent variable".

1. Number of Zn atoms

4 internal atoms = 4 Zn atoms

2. Number of S atoms

8 corners × ⅛ S atom/corner + 6 faces × ½ S atom/face = 1 S atom + 3 S atoms = 4 S atoms

3. Empirical formula

The atomic ratio is

4Zn:4S = 1Zn:1S

The empirical formula is ZnS.

What material beats and lets you get though all of earth’s layers?
Goryan [66]

Seismic waves

Explanation:

Seismic waves are disturbances that transmits energy elastically and let's scientist have a glimpse of the interior of the earth.

These waves can pass through any component layer of the earth due to their unique properties.

There are four types of seismic waves but the two body waves are the most important in studying the earth's interior.

  • Seismic p-waves can pass through any earth materials as they are longitudinal waves.
  • Seismic s-waves are shear waves and can only pass through solids. liquids and gases cannot be sheared.
