forced damped transverse vibration of a beam and verify Dunkerley’s empirical formula. According to Dunkerley’s empirical formula‚ 1f2=1fb2+1fω2 where f referring to the natural frequency of heavy beam with central load fb referring to the natural frequency of heavy beam only fω referring to the natural frequency of light beam with central load M By using the results of light damping‚ Dunkerley’s empirical formula would be studied and verified by comparing the calculated resonant frequency f

Molecular Formula | Key Concepts * Empirical Formula of a compound shows the ratio of elements present in a compound. * Molecular Formula of a compound shows how many atoms of each element are present in a molecule of the compound. * The empirical formula mass of a compound refers to the sum of the atomic masses of the elements present in the empirical formula. * The Molecular Mass (formula mass‚ formula weight or molecular weight) of a compound is a multiple of the empirical formula mass.

finish college? Will student loans help student to reach their goals? These are some of the questions that student may ask to their self when they are applying for student loan. Going to colleges is now hair-raising than before. Student loan can affect to the student for the rest of their life. Student loans are now rapidly increasing‚ more student having difficult time to pay their student load‚ and it does not guarantee a better career after they graduate. The student loan is tremendously increasing

project I built a car out of only paper‚ straws‚ wheels‚ and hot glue. The car was to protect and egg‚ comparable to how real cars protect us. If you built a car that did not protect the egg‚ it is comparable to you having been in a fatal car crash. II. Variables: * With the building of our cars‚ we were measuring the mass of the egg‚ mass of the car‚ time for it to go down the track‚ and the width so that it would fit down the track. The variable that affects our cars the most is the

very clear when they emphasized the boss would not be happy if no agreement was made. Was this negotiation different from the “Used Car” negotiation? Why or why not? This negotiation was different because in this negotiation the best result for both parties was working together in order to build a long term business relationship. The used car negotiation was a negotiation revolved around a singular item and most likely both the buyer and the seller would never meet again because it was a one time

Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚ if we resolved a sample of the compound NaOH weighing

Differences Between Ionic and Covalent Compounds Abstract In chemistry‚ a compound is a substance formed from two or more elements‚ with a fixed ratio determining the composition. A defining characteristic of a compound is that it has a chemical formula. Formulas describe the ratio of numbers of atoms in a substance. Compounds may have a number of possible phases. For a compound to be a liquid or a gas and still be called a compound‚ atoms from the various elements must be stuck together in
