The cable of a large crane applies a force of 2.2x10^4N to a demolition ball as it lifts it vertically a distance of 7.6m. a) How much work is done on the ball? b) Is the work positive or negative? Why? Solution: A.) W=( 2.2x10^4N) ( 7.6 m) W= 1.6x10^5 Nm or J B.) Positive‚ because the force

Solution Focused Therapy or Brief Therapy is a counselling technique that focuses on solutions in the present and future instead of the past. It is a short-term goal focused approach that moves clients away from their problems to solutions. Solution focused therapy is based on the idea that to help clients focus on things related to how change happens rather than concentrating on how problems develop. Solution focused therapy focuses on the future and how life will be better when their goals

Lactated Ringer’s Solution Lactated Ringer’s classified as an isotonic or crystalloid solution‚ has similar osmolarity to body fluids‚ meaning that it maintains fluid volumes in balance between the space inside and outside the blood vessels. Lactated Ringer’s contains electrolytes‚ substances necessary for cells to function. It’s intended for intravenous administration‚ but if a suitable vein cannot be found it can be given orally which has an unpleasant taste. It is made up of NaCl (sodium chloride)

Density of Solutions Lab Purpose: The purpose of this lab was to find out the densities of the known and unknown Solutions that were given to us. This can be found by dividing the mass by the volume of the Solutions. The other purpose of this lab was to perfect our skills in finding out the percentage error‚ uncertainties‚ random error‚ and systematic error. Variables: Independent: Mass Percentage of Solution (KCl); Unknown Solution; Temperature Dependent: Density Materials: 10.00 mL

This assignment must be submitted no later than November 22nd‚ 2011. 1. What is a true solution? Explain why the solute does not settle out of a solution. Is it possible to have one solid dissolved in another? Explain. In metals it would be called an alloy. 2. An aqueous solution of KCl is colorless‚ KMnO4 is purple‚ and K2Cr2O7 is orange. What color would you expect of an aqueous solution of Na2Cr2O7? Explain. Orange. 3. Explain why hexane will dissolve benzene but will not dissolve

However‚ growing up in such a small town and thinking of my community as one big family‚ I just assume that everyone treats one another equally. Which in fact‚ is not true at all. Studying this issue has taught me how hopeless you would feel if you get punished wrongfully by a police officer. Nobody can help you since the people whose job it is to protect are are actually abusing you. Studying different branches taught me how one person can create a large foundation fighting for what he/she believes

been watered down‚ to complete this task a sample of commercial vinegar was tested twice using titration and an average was taken of the two samples to give a base line to compare the potentially tampered samples against. Introduction Vinegar is a solution made from the fermentation of ethanol (CH3CH2OH)‚ which in turn was previously fermented from sugar. The fermentation of ethanol results in the production of acetic acid (CH3COOH). The typical pH of vinegar ranges anywhere from 2 to 3.5‚ although
