LAWS AND FORMULAS THAT HAS DIRECT PRPORTION IN SCIENCE
Henry's Law
Henry's law is one of the gas laws formulated by William Henry in 1803. It states: "At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid." An equivalent way of stating the law is that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid.
To explain this law, Henry derived the equation: C=kPgas
Hooke's Law
"Is proportional to" means "varies directly with", so the formula for Hooke's Law is "F = kd", where "F" is the force and "d" is the distance.
Coulomb’s Law
The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the scalar multiplication of the magnitudes of charges and inversely proportional to the square of the distance between them.
The force is along the straight line joining them. If the two charges have the same sign, the electrostatic force between them is repulsive; if they have different signs, the force between them is attractive.

Newton's law of universal gravitation states that any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance be wherein,

Ohm’s Law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship:

Joules’ heating Law also known as ohmic heating and resistive heating, is the process by which the passage of an electric current through a conductor releases heat.

Dalton’s Law states that in a mixture of non-reacting gases, the total pressure exerted is directly proportional to the sum of the partial pressures of the individual gases. Formula:

Amagat’s Law states that the extensive volume V = N·v of a gas mixture is equal to the sum of volumes Vi of the K component gases, if the temperature T and the pressure p remain the same.

Understanding how costs behave, whether costs are relevant to specific decisions, and how costs are affected by income taxes allows managers to determine the impact of changing costs and other factors on a variety of decisions. This chapter introduces concepts and tools that will be used in Chapters 6 through 8. Chapter 5 begins with a definition of cost behavior and illustrates the concepts of fixed costs, variable costs, and mixed costs. Next, the chapter revisits the concept of relevant costs (introduced in Chapter 1) as it applies to variable and fixed costs. The chapter also describes the impact of income taxes on costs. Learning Objectives After studying the material in this chapter, you should be able to: 1 Describe the nature and behavior of fixed, variable, and mixed costs Analyze mixed costs using regression analysis and the high/low method 2 Distinguish between relevant and irrelevant costs and apply the concept to decision making 3 Illustrate the impact of income taxes...

The Construction and Validation of an Achievement Test in College Physics for the Family Clinic Colleges S.Y. 2006 -2007

...CHAPTER I INTRODUCTION Background of the Study In any educational system there are three primary aspects of the learning-teaching process which are geared towards its end goal- that of growth and progress in knowledge, skills, abilities and attitudes of the students. First, educational goals are established either implicitly or explicitly. Secondly, learning experiences are designed to carry out the attainment of the goals. Finally, an evaluation is conducted to determine the extent to which the objectives have been established. This evaluation aspect has become the focus of study in the educational field. Evaluation involves the summing-up processes in which value judgments play a large part, as in grading and promoting students. Most educators considered that a school’s main business is promoting growth towards desirable and societal objectives; fewer agree on who should judge the desirability of these objectives. However, since all schools focus on student progress as the ultimate criterion, it is important to evaluate the status and gains of students expertly. If our evaluation procedures are poor, then the quality of the information on which we make judgments can not be adequate. Measurement and evaluation are indispensable to the growth of scientific education. They encompass judgments made by teachers and administrators. An important phase of this educational process involves the construction, administration, and scoring of tests. Before it is possible...

...Institutional factor grants Moving from current to the new funding framework February 2004 1 INCOME SOURCES OF PUBLIC HIGHER EDUCATION INSTITUTIONS The diagram below offers a broad summary of the ways in which funds flow to public universities and technikons in South Africa. Diagram 1: Sources of funds of public higher education institutions Government grants 50% Student tuition & other fees 25% Annual funds for public higher education 100% Other private income 25% The proportions reflected in the diagram are averages for the system as a whole. These proportions can differ widely between institutions. For example, government grants as a proportion of total income can be as low as 35% if an institution is able to raise large amounts of private funds through research contracts, donations and investments and can be as high as 65% in the case of institutions which are not able to generate substantial amounts of private income. The Ministry of Education has direct control over only government grants to public universities and technikons. The Ministry furthermore takes no account of income raised from student fees and other private sources when distributing government grants to individual institutions. These institutions are however required, as public entities, to submit to the Ministry annual financial statements which reflect all expenditures and all income from all public as well as private sources. This paper explains how the Ministry of Education...

Cost behavior is defined as, “how the activities of an organization affect its costs” (Burgstahler, Horngren, Schatzberg, Stratton, and Sundem, 2008). Cost behavior consists of variable costs and fixed costs. Variable costs are, “costs that change in direct proportion to changes in the costs driver” (Burgstahler et al., 2008). Examples of variable costs for Guillermo are materials, equipment, and labor (Guillermo, 2009). Fixed costs are, “costs that is not immediately affected by changes in the cost-driver level” (Burgstahler et al., 2008). Examples of fixed costs for Guillermo are labor, utilities, taxes, and etc (Guillermo, 2009). Cost behavior can affect the choice of the process...
