What are some different ways large or small distance can be measured?

Answers

Answer:

The method used for measuring the small distance is by using the scales and the distance measured over long distance is by inch tape or measuring tape.

Explanation:

Radar, the parallax method, and the triangulation method are used to calculate very long distances. Small distances are measured in centimeters and millimeters.

What are different ways of large or small measurement?

Length is measured in distance. For instance, the length of a road equals its distance. The most popular units of measurement for distance in the metric system are millimeters, centimeters, meters, and kilometers.

The various ways that length, distance, or range can be measured are referred to as length, distance, or range measurement (ranging).

The rulers, transit-time methods, and interferometer methods based on the speed of light are the methods that are most frequently used.

Calipers and micrometers are used for making small, accurate measurements.

Therefore, different ways large or small distance can be measured.

Answers

Answer:

Orbitals

Explanation:

An orbital is a region in space where there is a high probability of finding an electron. An orbital is a probability function put forward by the wave mechanical model of the atom.

The wave mechanical model derives its principles from the Heisenberg uncertainty principle and the principle of wave particle duality.

Since we can not describe the momentum or position of the electron at any time with certainty, an orbital is a probability function that describes the region in space where the electron may be found around the nucleus.

The mass of an unidentified rock is 40 grams. Students determine the volume of the rock by placing the rock in a cylinder with water. The students calculate the density of the rock. They determine the identity of the rock based on the density ranges in the table.

Answers

Answer:

A. Coal

Explanation:

[tex] Volume_{rock} [/tex] = water displaced by rock

Water displaced by rock = volume of water after rock is dropped into the cylinder - volume of water before the rock was dropped into the water

Water displaced by the rock = 180 ml - 150 ml = 30 ml

[tex] Volume_{rock} = 30 ml [/tex]

Density of rock:

40 grams => 30 ml

x grams => 1 ml

Cross multiply

1*40 = 30*x

40 = 30x

40/30 = 30x/30

1.3 = x

Density of rock = 1.3 g per 1 ml

Recall: 1 ml = 1 cm³

Therefore,

Density of the rock = 1.3 g/cm³

1.3 g/cm³ falls within the range of 1.1 - 1.4 g/cm³

Therefore, the rock is identified as Coal.

For ___, 2 lobes have positive signs while the other 2 have negative signs, showing that the opposite lobes of have same sign.​

Answers

Answer:d orbitals

Explanation: just trustme

Orbitals are defined as the mathematical function used to identify the probability of an electron of an atom in a specific region. The orbitals are s, p, d, and f.

The correct statement for the given blank is:

For d orbitals, 2 lobes have positive signs while the other 2 have negative signs, showing that the opposite lobes have the same sign.​

D-orbitals have 5 lobes, in which two lobes have positive signs and 2 lobes have negative signs.

The orbitals have positive and negative signs, as they represent the positive displacement of the wave, whereas negative displacement (down) of the wave is represented by the negative sign.

Therefore, the correct answer is d-orbitals.

Bonding is demonstrated using electron dot diagrams by representing the valence electrons that form bonds.

What do you mean by Bonding?

Atoms in molecules are joined by a chemical bond.  Electrostatic forces between negatively charged electrons and positively charged atomic nuclei give rise to bonds.

An electron dot diagram is a representation of the arrangement of valence electrons around an atomic symbol.

The outermost shell contains valence electrons, which are electrons. By representing the valence electrons, which are the ones responsible for bonding, in electron dot diagrams bonding is demonstrated.

As particles in a convection current are heated up, what happens to their speed and density?
A.) Particles speed up and get closer together, making their more dense.
B.) Particles speed up and spread out, making them less dense.
C.) Particles slow down and spread out, making them less dense.
D.) Particles slow down and get closer together, making them less dense.

Answers

Answer:

As they rise, they transfer their thermal energy to other particles of the fluid and cool off in the process. With less energy, the particles move more slowly, have fewer collisions, and move closer together. This increases their density, so they sink back down through the fluid
