Equilibrium is the state in which the competing influences of a system are balanced. In this experiment‚ four activities were conducted to study equilibrium namely Equilibrant Force‚ First Condition for Equilibrium‚ Locating the Center of Gravity and Second Condition of Equilibrium. The % Error obtained for the following activities were 14.13% and 2.35% for Activity 1‚ 4.90% for Activity 2 and 7.52% for Activity 4. Friction is the resistance to motion of one object moving relative to another

Cheese: A Home to Bacteria “Cheese is just a means of controlled spoilage‚” said Steve Jenkins‚ a Master Cheesemonger at Fairway Market. (Cheese) Bacteria‚ or starter cultures‚ control the flavor‚ hardness‚ type‚ and many more aspects of cheese. The two main strands of bacteria involved in cheese making are Lactococcus and Lactobacillus‚ which ferment sugars found in the milk. Humans have learned to manipulate bacteria and the fermentation process to produce different types of cheese such as Swiss

CHAPTER TWO Beneficial bacteria in the environment and their uses. In today’s world‚ the environment and its related issues are steadily gaining a lot of importance. Some bacteria are helpful and are used to obtain balance in the environment. It has been seen that helpful bacteria are useful in dissolving organic sludge from water‚ breaking down the growth of algae‚ reducing the various noxious odours such as hydrogen sulfide odours‚ reducing ammonia levels‚ promoting faster growth of fish in the

Abstract: Two parts of this lab were performed involving photosynthesis and cellular respiration. The first part of the lab consisted of cutting out spinach leaf disks with a straw and then putting them into syringes containing an infiltration solution and sodium bicarbonate. Then the syringes were place under the presence of light and watched as certain disks floated. This part of the lab consisted of watching photosynthesis take place. Then for the second part of the lab we tested cellular respiration

Ciara Clark and Caroline Bedenbaugh 4A Density Lab Objective : The purpose of this lab is to observe and explore the relationship of a substance’s volume vs. its mass‚ and to calculate an object’s density by using the relationship of its mass and volume. Data Tables : Data: Density of Water Run Mass of graduated cylinder volume of water added mass of water 1 25.28 g 0.00 mL 0.00 g 2 26.15 g 1.00 mL 0.87 g 3 27.18 g 2.00 mL 1.90 g 4 28.19 g 3.00 mL 2.91 g 5 29.13 g 4.00 mL

of mass‚ you have to do two trials to narrow the uncertainty. Then add 100 g masses one by one to the mass hanger and record the extension of the spring and the time taken for that size of mass to complete twenty oscillations. You will be given an unknown mass and also record the time taken of that mass to oscillate twenty

Answer the following: Mimi Meowz is a large designer-clothing company that sells mainly to large retail department stores‚ as well as to smaller boutique shops. The company requires its salespeople to use notebook computers to enter orders from customers.

Title- Protista Lab Concept- the concept of this lab was to explore what is in the pond water as living organisms and try to identify what it is. Some types of Protista are multi-cellular like giant kelp. Although they look much like plants‚ multi-cellular protists lack specialized tissues. Being eukaryotes‚ they have a membrane-bound true nucleus with linear chromosomes‚ and they have membrane-bound organelles. The kingdom Protista contains all eukaryotes that are not plants‚ animals‚ or fungi

Corte Madera Scientific Report Abstract I examine how rising or falling tide can affect the water level of Corte Madera Salt Marsh in this report. The data is from Wednesday (June 19th) and Thursday (June 20th). My hypothesis is that tide and water level have positive relationship. From the result‚ I learn that the water level and tide have positive relationship. However‚ when tide changes its direction‚ the water level is likely to stay or little change. Introduction On June 19th‚ my
