Abstract

Suppose is any group and then the smallest subgroup of containing is the intersection of all subgroups of containing and denoted by . If then , such a subgroup we know as a cyclic group with generator , such that the order of is the same as the order of . In this research, observations were made on the set in order to know the nature of the membership of and the order of for the case of order 2 and further for of order n if G is a cyclic finite group using the effect of Lagrange Theorem.

Abstract

Simulations have been carried out of equal power for lithium batteries with one-way diffraction grating deformation using magnetic induction coils which are converted into heat energy to heat a certain volume of water. The heating time was observed from the initial temperature of 30 degrees Celsius to the final temperature of 100 degrees Celsius for each coil length L. Using multiple linear regression analysis, a power change ratio of 0.95 was obtained. This means that the battery power will increase by 0.05 or 5 percent if it is treated with a compressive force to the limit of elasticity. This is possible because Lithium has a Young's modulus of 4.9 GPa, a shear modulus of 4.2 GPa, and a bulk modulus of 11 GPa.
