CHAPTER ONE INTRODUCTION A. STATEMENT OF THE PROBLEM This study aims to find out how long a lemon (Citrus limon) can last as a lemon battery powering a digital clock. B. HYPOTHESIS The researcher assumes that one lemon would last for a day or two and that the usage of more lemons would entail a longer battery time. C. OBJECTIVES Specifically‚ it aims to: 1) come up with a quantity-longevity ratio with the use of a varied quantity of lemons in the production of a lemon battery 2) find

Enzymes are biological catalysts that speed up chemical reactions by lowering the amount of activation energy needed to start the reaction and let the reaction occur at temperatures found in living cells. The way that enzymes do this is explained with the lock and key hypothesis. This hypothesis says enzymes have a specific shape called the active site which is different between different enzymes. Molecules called the substrate that participates in the reaction also have a specific shape that can

Paragraph 1 Perovskite‚ with a general formula of ABO3‚ has a structure comparable to that of ReO3. What differentiates them is the fact that ReO3 lacks the cation A at its unit cell centres. An octahedron made up of six oxygen atoms encompasses each rhenium atom‚ and it forms the 3-dimensional structure by connecting its corners with other octahedral. At low temperatures and a pressure of about 3kbar‚ the Fermi-surface cross sections undergo nonlinear patterns. ReO3 thus undergoes phase transitions

Marques Harvey PHIL 201 9/25/14 Immanuel Kant: Knowledge Is Both Rational and Empirical Immanuel Kant was renowned German philosopher who sought to reconcile the Continental rational philosophies with those of the British empirical philosophers. The rationalist philosophers‚ such as Descartes‚ believed that the fundamental source of all knowledge was not simply observation‚ but that it was a priori‚ which is independent of experience. It’s different from a posteriori‚ which is known as experiential
