Amid high food prices in 1972‚ Sweden’s National Board of Health and Welfare developed the idea of "basic foods" that were both cheap and nutritious‚ and "supplemental foods" that added nutrition missing from the basic foods. Anna Britt Agnsäter‚ head of the test kitchen at KF‚ a consumer co-op that worked with the Board‚ held a lecture the next year on how to illustrate these food groups. Attendee Fjalar Clemes suggested a triangle displaying basic foods at the base. Agnsäter developed the idea

Chapter 13 – States of Matter Pressure (P) – the amount of force per unit area. Pressure=F/a or P=F/a Pascal’s Principle “Any change in pressure at a point on a confined fluid is transmitted throughout the fluid”. Any change is transmitted throughout the fluid. Buoyancy & Archimedes Principle “When an object is submerged in a fluid‚ it displaces a certain volume of that fluid. The amount of force pushing upward on the object is equal to the density of the fluid (Ï) times the acceleration

Journal #2 ENG 091 #96426 Going through chapters 1-7 of Hitchhiker’s guide to the Galaxy was impossible. I had to read more. I am not done with the book yet though. I felt like I was reading an anime. I could picture the scene of what I was reading so clearly that it felt like my body was there. I loved the way they represented what happened to Arthur on planet earth in a gross way where the house to be demolished for a pathway was the earth in the galactic space. I loved the idea of having a

KINEMATICS REVIEW LESSON EXAMPLE 1: Consider the velocity vs. time graph below. The motion of five different people (A‚ B‚ C‚ D‚ and E) are shown on the graph. Study the graph and answer the following questions. Some questions may have more than or less than one answer. Question: 1. Which person(s) changes direction during the time of motion? 2. Which person(s) is/are not moving? 3. Which person has the greatest average speed? 4. Which person(s) has/have a constant‚ positive acceleration

Calculations- 1. Main Show Tank Calculation: The main show tanks radius is 70 feet. Based on that the tank is a sphere-shaped and we have to find the volume‚ I used the formula for the sphere volume which is: V= 4/3(3.14 x r^3) V= 4/3(3.14 x 70^3) V= 4/3(1‚077‚020) V= 1‚436‚026.66666... V= 1‚436‚027 But I have to find the volume of the quarter sphere-shaped‚ so: V= 1/4 x 1‚436‚027 V= 359‚007 The volume of the quarter-shaped tank is 359‚007 cubic feet Holding Tank Calculations- 2.

Newton’s Laws of Motion and Gravity Define mass‚ weight‚ force‚ and acceleration. Mass – A measure of the total amount of material in a body‚ defined either by the inertial properties of the body or by its gravitational influence on other bodies. It is proportional to‚ but not the same as‚ its mass Force – A quantitative description of the interaction between two physical bodies‚ such as an object and its environment. Force is proportional to acceleration. Acceleration – A vector quantity that

The eye of a hurricane passes over New Orleans in a direction 60.0° north of west with a speed of 41.0 km/hr. Three hours later‚ the hurricane suddenly shifts due north‚ and its speed slows to 25.0 km/hr. How far from New Orleans is the hurricane 4.50 hours after it passes over the city? v1 = 41.0km/hr(cos30°‚ sin30°) = (35.5‚ 20.5) km/hr v2 = (0‚ 25.0)km/hr → D = v1×3hrs + v2 × 1.5hrs =Answer (105.9‚ 99) km A ship which can move at the velocity of v0 = (12‚ 6) m/s (x-axis: the West to the
