1.Summarize the formation of friction ridge skin and how it relates to the permanence of fingerprints. The skin over most of our bodies is fairly smooth. ’Friction Ridges ’‚ however‚ are found on the digits‚ palms and soles. They are called ’friction ’ ridges because of their biological function that helps us grasp and hold onto objects. Sometimes compared to fine lines found in corduroy‚ unlike corduroy‚ ridges vary in length and width‚ branch off‚ end suddenly and‚ for the most part‚ flow with

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Measurement of the fluid flow‚ often must understand its flow‚ flow rate distribution. Reynolds number is the characterization of fluid flow characteristics of an important parameter. Fluid flow when the inertial force F g and viscous forces (the friction) F m ratio known as the Reynolds number. OBJECTIVES The main objectives of conducting this experiment were: 1. To visualize laminar‚ transitional and turbulent flows. 2. To determine the conditions under which types of flow occur.

In labs 4.1‚ 4.2‚ and 4.3‚ the connection between the force of gravity and the type of surface was tested through a series of experiments. In lab 4.1‚ the force of gravity was tested through various surface types‚ including: tabletop‚ waxed paper‚ paper towel‚ fine sandpaper‚ and coarse sand paper. In lab 4.2‚ two different surface types that were tested included: tabletop and coarse sand paper. This lab compared the two averages between both tabletop and coarse sandpaper using different amounts

African Diaspora and the World After reading the short story “Diaspora” by Joanne Hyppolite‚ I got a vivid understanding of how diaspora can have an effect on one’s identity. Over the past month we have studied many theories and concepts concerning race‚ gender‚ and politics. There are three theories that capture the essence of Joanne Hyppolite’s worldview as a Haitian growing up in America: intersectionality‚ identity‚ and diaspora. Individuals oftentimes experience the theory of Intersectionality

Uniform Acceleration Cedric C. Labasan Physics Department‚ De La Salle University St. Joseph Hall Room 404‚ 2401‚ Taft Avenue‚ Manila‚ Philippines cedric_labasan@dlsu.ph Abstract This lab report defines what uniform acceleration is and how to calculate uniform acceleration of a cart rolling down a ramp at different angles and elevations. The experiment will be performed by setting the cart on the track against the end stop and then record this final position on the steel ramp ten times
