are some of the advantages and disadvantages of shortening project schedules? In some situations project manager will have to get the project schedule shortened. One method for accomplishing this is by shortening the durations of the activities in the critical path. This can be done by allocating more resources to perform the activities or by making changes in the scope. Project Crashing and Fast Tracking are two methods useful for shortening the project schedule. Crashing is a

PROJECTILE MOTION PRACTICE QUESTIONS (WITH ANSWERS) * challenge questions Q1. A golfer practising on a range with an elevated tee 4.9 m above the fairway is able to strike a ball so that it leaves the club with a horizontal velocity of 20 m s–1. (Assume the acceleration due to gravity is 9.80 m s–2‚ and the effects of air resistance may be ignored unless otherwise stated.) a b c d e How long after the ball leaves the club will it land on the fairway? What horizontal distance will the ball travel

1. Two ships P and Q are moving along straight lines with constant velocities. Initially P is at a point O and the position vector of Q relative to O is (6i + 12j) km‚ where i and j are unit vectors directed due east and due north respectively. The ship P is moving with velocity 10j km h–1 and Q is moving with velocity (−8i + 6j) km h−1. At time t hours the position vectors of P and Q relative to O are p km and q km respectively.

PHYSIOEX 9‚ ACTIVITY #3 Review Questions ACTIVITY #1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability

Then complete the discussion by supplying or choosing the appropriate terms. To maintain life‚ organisms must be able to convert energy from one form to another. For example‚ in the process of photosynthesis‚ algae‚ plants‚ and photosynthetic prokaryotes use the energy from sunlight to convert carbon dioxide and water to glucose and oxygen (a waste product).

It has recently come to my attention that other schools have been thinking about shortening the school week to four days instead of five. Of course‚ at first glance‚ this proposition sounds like all of your dreams have come true! Three day weekend every weekend! However‚ there are many reasons that schools should NOT enforce this rule. First off‚ the government requires you to attend school a certain amount of time a day and a certain amount of time a year. With five day weeks and normal hours‚

Teen Angst and the Essence of Adolescence The Highest Tide has two prominent themes‚ exploration of marine life and teen angst. The main character‚ Miles along with his other adolescent friends and foes (A.K.A.‚ Frankie Marx) perfectly exhibit the symptoms of the phenomena that is teen angst. Symptoms such as defiance of authority figures‚ self-centered tendencies‚ emotional turmoil and adventures of sexuality both fit under the category of teen angst/adolescence and are examples presented in the

obtained‚ what is the effect of the height of the track to the cart’s acceleration? The data shows that sinӨ‚ which is dependent on the height‚ is getting higher as acceleration is increasing. This implicates that when object is at higher altitude‚ its acceleration is faster. 2. From the data obtained‚ how is time‚ t related to the inclination of the track? Explain why? Time and position of velocity are interrelated to each other and the height and gravitational pull affects the acceleration of a moving
