Answer:

It would be very unlikely that a volcanic eruption will occur in the mainland (Midwest or surrounding) to occur.

Explanation:

The nearest platonic plates are in California in the triangle with Japan and China, the chances of earthquakes are also low in this area due to the fact that no plates could collide to produce an earthquake, or form a volcano.

Sound travels faster through solids than it does through either liquids or gases a student could verify this statement by

irina [24]

Group of answer choices.

A. Distance that sound travels through a solid, a liquid, and a gas.

B. Pitch of sound when it passes through a solid, a liquid, and a gas.

C. Distance sound travels through a solid, a liquid, and a gas at varying temperatures.

D. Time required for sound to travel a set distance through a solid, a liquid, and a gas.

Answer:

D. Time required for sound to travel a set distance through a solid, a liquid, and a gas.

Explanation:

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.

Sound travels faster through solids than it does through either liquids or gases. A student could verify this statement by measuring the time required for sound to travel a set distance through a solid, a liquid, and a gas.

Mathematically, the time required for sound to travel is given by this formula;

$Time = \frac {distance (x)}{speed (v)}$

Hence, the time taken for sound to travel through each medium (solid, liquid and gas) would be measured, recorded and compared to one another.

According to the bohr model, what determines the shortest wavelength in a given series of wavelengths emitted by the atom?

algol13

According to the bohr model "The lower energy level into which the electron deflects from a higher energy level is designated by the quantum number nf" determines the shortest wavelength in a given series of wavelengths emitted by the atom.

By explaining that electrons move in fixed orbitals (shells) and not anywhere in between, Bohr theory amended the atomic structure model.

He also showed that each orbit (shell) has a fixed energy. Bohr refined Rutherford's model of the atom's nucleus to include electrons and their varying energy levels.

According to Rydberg formula

1/λ = R [1/ni² - 1/nf²]

λ = wavelength

R = Rydberg constant

ni & nf are integers or principal quantum numbers where nf > ni

So if we want wavelength(λ) to be shortest, then 1/nf should be zero.

In this way , it depends on nf and not on ni

That's why the lower energy level into which the electron deflects from a higher energy level is designated by the quantum number nf" determines the shortest wavelength in a given series of wavelengths emitted by the atom.

What makes water so good at dissolving other things

Nina [5.8K]

Water molecules are polar. Water has the ability to dissolve a variety of different substances. Water dissolves more substances than any other liquid. Water has excellent chemical composition and physical attributes. This is why water is such a great solvent.

Hope this helps!

How do cations form?

d1i1m1o1n [39]

For cations, the loss of an electron leaves them with a net positive charge, whereas for anions, the addition of an electron leaves them with a net negative charge. Understanding the processes behind this, including the ionization energy and electron affinity of different atoms, helps you see why certain atoms become ions more easily than others and what causes it to happen.
