Physics
1 answer:
Makovka662 [10]3 years ago
5 0

Answer:

All the given option is false.

Explanation:

A)

This is not true for all the materials like composite because the Poisson ratio for composite material can be negative that is why positive tensile stress may produce positive lateral strain.

B)

This is not true for all the material because the Poisson ratio for some material can be positive  that is why positive tensile stress may produce negative lateral strain.

C)

The explanation is same as option A.

D)

This is not true for all the materials ,It is valid only up to elastic limit .After the elastic limit the strain and stress does not follow linear path.

E)

This is not true for all the materials because some materials like composite is having negative value of Young's modulus.

Therefore all the given option is false.

What is the difference between sodium atom and a sodium ion
ludmilkaskok [199]
Pretty much any element(in your case sodium) contain these properties.

Atoms can be an ion, but not all ions are atoms. The difference between an atom and an ion has to do with net electrical charge. An ion is a particle or collection of particles with a net positive or negative charge. ... A stable atom contains the same number of electrons as protons and no net charge

Describe the movement of air over 2 nearby land areas, one of which is heated more than the other.
77julia77 [94]
In this case, the air from the warm area will always start moving towards the colder areas because as the temperature in both lands should be equal. This is one of the laws of thermodynamics.

The physical model of the sun’s interior has been confirmed by observations of
Inga [223]

The physical model of the sun's interior has been confirmed by observations of neutrino and seismic vibrations.

<u>Explanation:</u>

Sun's interior is composed of very high temperature and solar flares. So it is very difficult to understand the interior of the sun. But by using the vibrations of neutrino and seismic waves emitted by the solar waves, the physical model can be assumed.

As the interior of the sun performs continuous chain of hydrogen cycle. So the continuous emission of energy from the chain reaction releases neutrino. So these vibrations in neutrino and seismic vibrations, the physical model can be assumed easily.
