the earth is squeezed to the size of the moon, then what will be its effect on the gravity of the earth​

Answer: the correct options are

- were once connected

- are slowly drifting

Explanation: The continent is the main land mass of the earth which includes the following:

- Asia, Africa, Europe, Australia, North America, South America, and Antarctica.

These continents were once connected forming a supercontinent called PANGAEA

during the late palaeozoic and early mesozoic eras, millions of years ago.

Alfred Wegener, who is a German meteorologist, in 1912 came up with a hypothesis that the continents are slowly drifting the earth. He called the movement continental drift.

The continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics. In recent studies, through the science of plate tectonics, we where able to understand the mechanism through which continental drift occurs. The mechanism includes:

- processes of seafloor spreading,

- rift valley formation, and

- subduction (where heavier tectonic plates sink beneath lighter ones).

Answer:

Were once connected, and Are slowly drifting

Explanation:

It's called the continental drift, At first, Wegener's theory was dismissed. No one believed that the continents moved. During the 1920s, another scientist named Arthur Holmes suggested that the magma in the earth's mantle moved through convection currents. As hot magma rose toward the crust, it cooled and then sank back down. The cycle continued over and over, causing motion that was powerful enough to move the continents. Like Wegener's theory, Holmes' idea was not accepted by the scientific community. Forty years later, geologists compared mineral and fossil samples from Africa to those in South America. The samples matched perfectly. Today, the theory of continental drift is supported by a large amount of data and evidence. The continents as a whole was once called Pangaea.

Answer :

1) Luster →  the shininess of a material

2) Freezing point → temperature at which a liquid becomes a solid

3) Viscosity → the measure of a substance's resistance to flow

4) Solubility → ability to dissolve in another substance

5) Ductility → able to be pulled into a wire

Explanation :

Luster : It is defined as the material which has the shining property.

Freezing point : It is the temperature at which the phase changes from liquid state to solid state at low temperature.

Viscosity : It measures the resistance of the liquids to flow .

Solubility : It is defined as the ability of a substance (solute) to dissolve into a liquid (solvent).

Ductility : It is defined as the ability of a metal into a thin wire without breaking.

Final answer:

The physical properties are correctly matched as: Luster corresponds to the shininess of a material, freezing point is the temperature at which a liquid becomes solid, viscosity is the measure of a substance's resistance to flow, solubility is the ability to dissolve in another substance, and ductility refers to a substance's ability to be pulled into a wire

Explanation:

The correct matches for the physical properties and their descriptions are as follows:

1. Luster is the shininess of a material.
2. Freezing point is the temperature at which a liquid becomes a solid.
3. Viscosity is the measure of a substance's resistance to flow.
4. Solubility is the ability to dissolve in another substance.
5. Ductility is the property to be pulled into a wire.

It's crucial to understand these properties in chemistry, as they help us identify and characterize different substances.

Answer:

Psychiatrist prescribes medication for depression.

Explanation:

took the question

Answer:

A psychiatrist prescribes medication for depression.

The answer would be:

A. Longer wires have less resistance.

Here is why:

The statement is false because longer wires tend to have greater resistance. Look at the formula of resistance below:

ρ = resistivity

L = length

A = cross-sectional area

As you can see Length of the wire is directly proportional to the resistance, which means as the Length increases, the Resistance increases.

Answer:

A. Longer wires have less resistance.
