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

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

3.4 Thermal Effect Shear strain In general‚ increase in temperature causes the atoms to vibrate more and makes average atomic spacing greater. Macroscopically‚ this will lead to dimension increase in solid: T + T +V T – T – V In an isotropic material‚ temperature change only introduces variation of direct (normal) strain. In other words‚ thermal deformation does not cause shear strain. where T0 is a reference temperature and = coefficient of thermal expansion (C)-1 Hooke’s

Procedure and Analysis: The lab began with the group making a rough estimate of the force required from each arm to lift the weight up to be about 700N per arm. We then drew a force diagram for the force acting on the barbell and when the lifter held the barbell over his head. Were: B= the angle=35 degrees Fn= The normal force m= mass g=gravity F= the force exerted by each arm We then used the following equation W = mg to calculate the weight of the barbell. Were: W= weight

There are many similarities between Beethoven’s Symphony No. 5 in C Minor and Mozart’s Symphony no. 40 in G Minor. For example‚ both works have extremely recognizable motives. These works have been played on commercials‚ in advertising‚ and in places most people can’t even pinpoint. One of the main reasons is that these works carry strong motives that reoccur both rhythmically and melodically throughout the pieces. The opening four notes to Beethoven’s work may possibly be the most recognizable

Maroon 5 is an American pop rock band from Los Angeles‚ California.[1][2][3] The group originally formed in 1994 as Kara’s Flowers while they were still attending high school. With a line-up of Adam Levine‚ Jesse Carmichael‚ Mickey Madden and Ryan Dusick‚ they signed to Reprise Records and released an album‚ The Fourth World‚ in 1997. After a tepid response to the album‚ the band parted with their record label and attended college. In 2001‚ the band regrouped and added James Valentine to the lineup

Competitive Forces (Porter’s 5 Forces) Analysis of the competitive environment can be done utilising Michael Porter’s 5-forces model of UPS and FedEx. Porter’s theoretical framework allows us to determine the overall profitability and sustainability within the industry (Laudon & Laudon 2006‚ pg.99; Hubbard 2004‚ pg.211). We reckon that in this case‚ the competitive forces for both UPS and FedEx are very similar because they are both in the same industry. Power of substitutes: Communications

Intermolecular Forces Intermolecular forces are forces of attraction or repulsion which act between neighboring particles (atoms‚ molecules or ions). They are weak compared to the intramolecular forces‚ the forces which keep a molecule together. There are a few types of attractive intermolecular forces such as: Dipole-Dipole Forces Dipole–dipole interactions are electrostatic interactions of permanent dipoles in molecules. These interactions tend to align the molecules to increase the attraction
