Donor Services

1) Joanna’s diagnosis was that the department was fairly inefficient. There was a large discrepancy in between work load distribution, with mounds of paper work piling up with Magdalena and some of the newer workers, while the clique had time to sit around, gossip and not do work. Another thing was that Sam and Jose never looked at any of the work done by the department. They only reviewed the case histories. The employees couldn’t really explain why their jobs…

Vacations_ Psychology and Family

Picture yourself sitting on the beach. It’s a warm sunny day and the sun is beating down on you, warming every inch of your body. You have forgotten every itsy bitsy, as well as mega-problem back at home, your mind has been cleared blank from stress, and all you can think about is how amazing it feels to be lying on the beach doing nothing. People every year miss out on going on vacations. And yet, “getting away from the…

Bayfield Mud Company

The Bayfield Mud Company has had some problems with their 50 pound bags of treating agents. They sent shipped some bags to Wet Land Drilling, Inc. that were found to be short-weight by approximately 5%. Wet Land first did their own research on how many bags were short and by how much. They randomly sampled 50 bags and found the average net weight to be 47.51 pounds. Wet Land then contacted Bayfield Mud about the situation. Bayfield gave a 5%…

Projectile Motion

I. Introduction In this lab the main focus was projectile motion. A projectile is an object flying through the air that is only under the force of gravity (neglecting air resistance). A projectile moves both horizontally and vertically, which creates a parabolic flight path. In vertical projectile motion there is a constant velocity since there are no forces in the horizontal direction (neglecting drag due to air resistance). Consequently, there is no acceleration in horizontal projectile motion. In vertical projectile…

Problems of Working Women

The financial demands on the Indian families are becoming fiercer by day. The sky rocketing cost of living, increasing expenses on education of children, increasing cost of housing properties in India force every family in India to look for ways and means of increasing the household income. As a result, women in India who were mostly known as homemakers are forced to go for jobs and take up even careers that were considered only suitable for men such as working…

How Airplanes Work

Human flight has become a tired fact of modern life. At any given moment, roughly 5,000 airplanes crisscross the skies above the United States alone, amounting to an estimated 64 million commercial and private takeoffs every year [source:NATCA]. Consider the rest of the world’s flight activity, and the grand total is incalculable. It is easy to take the physics of flight for granted, as well as the ways in which we exploit them to achieve flight. We often glimpse a…

Torque_ Second Condition of Equilibrium

A torque is an influence, which tends to change the rotational motion of an object. One way to quantify a torque is force applied times the lever arm. In this experiment we consider the systems in equilibrium and its applications and how the forces acting on the system affect torque. To serve as a guide there are objectives set in performing this experiment. First objective is by the second condition applied to the systems of equilibrium and the second objective…

Use of Force

Use of force can be defined as the right granted to the authority or an individual to settle conflicts through measures that are aimed at either preventing or dissuading a given party from a certain course of action or physical intervention to stop the individual(s) from taking a certain course of action. As such, use of force may be applied by the military, the police, other security personnel or corrections in an effort to stop or prevent crime. The executive…

Polygon of Forces

Static equilibrium of forces was investigated through the use of different weights attached to cords which were connected to a central ring, while pulleys supported them. This assembly facilitated the force band system to demonstrate that equilibrium will be attaining regardless of disturbances. However, due to errors in the experiment, the sum of the x and y component did equate to zero as predicted. The graphical solution of the experiment yield a polygon that is completed indicating that all the…

Fluid Mechanics

2.15 A team is designing a helium-filled balloon that will fly to an altitude of 24,000 m. As the balloon ascends, the upward force (buoyant force) will need to exceed the total weight. Thus, weight is critical. Estimate the weight (in newtons) of the helium inside the balloon. The balloon is inflated at a site where the atmospheric pressure is 0.89 bar and the temperature is 22°C. When inflated prior to launch, the balloon is spherical (radius 1.3 m) and…

Tension of a Liquid

TITLE To measure surface tension of a Liquid OBJECTIVE The aim of this physics experiment is to use a domestic single-beam weighing scale to straight away measure the surface tension of a liquid. INTRODUCTION Surface tension is defined as the quantity of energy necessary to increase the surface area of a liquid by a unit amount. The unit for Surface tension is expressed in joules / square meter or (J/m2). Also, the units can be expressed as force per unit…

Simple Machines

Simple machines are extremely important to everyday life. They make stuff that is normally difficult a piece of cake. There are several types of simple machines. The first simple machine is a lever. A lever consists of a fulcrum, load, and effort force. A fulcrum is the support. The placing of the fulcrum changes the amount of force and distance it will take in order to move an object. The load is the applied force. The effort force is the…

Acceleration Due to Gravity

The acceleration due to gravity, g, was determined by dropping a metal bearing and measuring the free-fall time with a pendulum of known period. The measured value is 9.706 m/s2 with a standard deviation of 0.0317, which does not fall within the range of known terrestrial values. Centrifugal forces and altitude variations cannot account for the discrepancy. The calculation is very sensitive to the measured drop time, making it the likely source of error. (Short, sweet and to the point….

Activity 1.1.2 Simple Machines Practice Problems Answer Key

Answer the following questions regarding simple machine systems. Each question requires proper illustration and annotation, including labeling of forces, distances, direction, and unknown values. Illustrations should consist of basic simple machine functional sketches rather than realistic pictorials. Be sure to document all solution steps and proper units. All problem calculations should assume ideal conditions and no friction loss. Simple Machines – Lever A first class lever in static equilibrium has a 50lb resistance force and 15lb effort force. The lever’s…

War Is a Force That Gives Us Meaning

The book “War Is a Force That Gives Us Meaning” by Chris Hedges provides in-depth discussion of the appeal and pull of war on national actions and attitude of people towards the war. The author highlights fifteen years of experience and reports through his own prism the very nature of the war, its causes and terrible consequences such as numerous deaths, hunger, cataclysms, etc. Moreover, Hedges discusses physical and moral devastation the war leaves. The author claims that war should…
