A nonlinear oscillator potential was substituted into the radial part of the Schrodinger wave equation and solved using the Frobenius method to obtain the energy eigenvalues of the system. The partition function and the energy eigenvalues are used to determine three thermal properties for four polyatomic molecules which showed that added energy is required in the absence of the nonlinear term as the orbital and magnetic quantum numbers are increased and degeneracy completely removed. Other findings also reveal that as the virial coefficients of the four polyatomic molecules vary, the additive property of entropy is observed as well as the enhancement of the mean energy approximately proportional to the volume of the molecules. The four polyatomic molecules under consideration are environmentally impactful and are indispensable to man.","PeriodicalId":326537,"journal":{"name":"Journal of Physical Mathematics & its Applications","volume":"10 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140412643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clearly, transformation of a circle determines the ratio of expansion- in relation to its radius given that it is increasing by half. Thus, as the difference of the areas of the relative circles is half of pi; then subtracting the larger area of a circle from its larger relative square which is within its circumference: with that of the smaller area of a circle whose smaller square is also within its radius- results into half of pi minus half. Where then it is easier from such, to deduce the Archimedes constant.while the GDP is projected to increase from $603 billion in 2020 to $15 trillion in 2063. The military spending is projected to increase from $2.6 billion to $33.94 billion, and the trade balance is projected to increase from $15 billion in 2020 to $29.99 billion in 2063.

Will the beam still hit this point, or will it hit the ceiling behind this point? In the years around 1900 scientists were convinced that photons get a lateral momentum in the direction of movement, because they are particles. But R. Feynman concluded that a mirror emits new photons and is therefore a light source and together with Einstein’s second STR-postulate the laser beam should hit the ceiling behind this point. This can be tested with the return rates of photons from a mirror on the Moon. The results show clearly with an error of probability < 10-80 that photons do not get a lateral momentum but arrive at that location where the Earth was 2.55 seconds before. Besides the detection of an additional velocity of Earth in the Universe this article proves that Einstein’s geometric spacetime idea is wrong because the physical basis for that is wrong","PeriodicalId":326537,"journal":{"name":"Journal of Physical Mathematics &amp; its Applications","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128305614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
