The image shows two spheres hung from a thin rope. The spheres do not affect each other.

A cubic piece of metal measures 3.00 cm on each edge. If the metal is nickel, whose density is 8.90 g/cm3, what is the mass of t

blsea [12.9K]

V = 3.00 x 3.00 x 3.00 => 27 cm³

D = m / V

8.90 = m / 27

m = 8.90 x 27

m = 240.3 g

A planet orbiting the Sun will experience the largest gravitational force and greatest tangential speed when it is

Travka [436]

Answer:

A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.

When people run long distances, their muscles require increased amounts of oxygen. Which system is responsible for carrying this

Juliette [100K]

The circulatory system is responsible for bringing food and oxygen to every cell in your body. The respiratory system is responsible for carrying oxygen and carbon dioxide in and out of your body.

Hope this helps :)

The following name is wrong. Draw the structure based on it and correct the name: 1,1,1âˆ’trimethylheptane

Nana76 [90]

2,2-Dimethyloctane is the correct name.

Eight C atoms make up the longest continuous carbon chain, hence the term "octane" for this molecule.

<h3>Description of the chemical structure</h3>

There are 31 bonds in the 2,2-Dimethyloctane molecule overall (s) There are 5 rotatable bonds and 9 non-H bonds (s).
Skeletal formula, which is the accepted notation for organic compounds, is another name for the 2D chemical structure illustration of 2,2-Dimethyloctane.
Skeletal formula, which is the accepted notation for organic compounds, is another name for the 2D chemical structure illustration of 2,2-Dimethyloctane.
In the 2,2-Dimethyloctane chemical structure, the carbon atoms are implied to be at the corner(s) and hydrogen atoms coupled to carbon atoms are not mentioned; instead, it is assumed that each carbon atom is connected to enough hydrogen atoms to form four bonds.
Based on the ball-and-stick model, which shows both the three-dimensional position of the atoms and the bonds tying them together, the 3D chemical structure image of 2,2-Dimethyloctane is created.
In order to provide a clearer picture of the atoms and bonds throughout the 2,2-Dimethyloctane chemical structure model, the radius of the spheres is thus smaller than the rod lengths.
