one of the following relationships between T and P must be true? Ans) P= T+25N UNIT IS Newton(N) Question no 22) If you swing a bucket of water fast enough in a vertical circle‚ at the highest point the water does not spill out because an outward force balances the pull of gravity on the water. Ans) False Question no 23)Suppose a highway curve is properly banked to eliminate friction for a speed of 45 mph. If your tires were bald and you wanted to avoid sliding on the road‚ you would have to drive

because their velocities will the larger and will need a larger force to go downwards. Air resistance of an object is affected by its mass‚ the total surface area that is exposed by the air resistance‚ and how fast an object is falling. When an object is falling‚ the force diagram will be represented by the force of air of an object pointing upwards and the force of gravity pointing downwards. But the value of the force of air and the force of gravity will not be the same in the beginning of the fall

Name: Lauren Date: February 15‚ 2016 Title: May The Force Be With You Abstract: Experimental Question: How does the mass of the first model source car affect the acceleration of the second model source car at rest to in motion? Research: When we drive our cars‚ motorcycles‚ trucks‚ or any vehicle down the road‚ we are driving them at a certain velocity and direction. All vehicles have a mass to the order of a few hundred pounds. When our vehicles move at a certain speed down the road‚ they create

Title : Shear Force and Bending Moment Objective : To determine the shear force and bending moment when concentrated load‚ symmetrical load and non symmetrical load are applied Introduction The shear force (F) in a beam at any section‚ X‚ is the force transverse to the beam tending cause it to shear across the section. The shear force at any section is taken as positive if the right-hand side tends to slide downwards relative to the left hand portion. The negative force tends to cause

IKEA‚ the Swedish furniture conglomerate‚ has taken on aggressive growth goals over the past several years in an effort to remain competitive. With this in mind‚ Michael Porter ’s "5 Forces" are applied to IKEA for better understanding of the organization as such: INTERNAL RIVALRY/COMPETITORS- The organization operates in a highly competitive industry‚ characterized by other low priced furniture producers such as Galiform of England and retailers such as Wal-Mart of the United States.

5 forces of Porter The 5 forces of Porter are named after Michael E. Porter. This model classifies and examines the competitive forces that characterize every single industry plus it helps to give a clear understanding of what the strengths and weaknesses are of each type of industry. In addition to this‚ the 5 forces of Porter were mainly designed as a response to the famous “SWOT Analysis”. These 5 forces are the following: 1. Competition in the industry 2. Potential of new entrants

sailboat moves north for a distance of 10.00 km when blown by a wind from the exact southeast with a force of 2.00 × 104 N. The sailboat travels the distance in 1.0 h. How much work was done by the wind? What was the wind’s power? Your response should include all of your work and a free-body diagram. Answer: Power is work done per unit time and workdone is force times the displacement. Hence power equal force * displacement / time. P = 2e4*10 / 3600s = 55.56 W. (10 points) Score 0. A sailor
