This is because whilst the pendulum is swinging‚ it may hit me in my eyes‚ as the pendulum is at a similar level of height to my head. I will also clear all the chairs‚ coats and bags from the vicinity as they may cause obstruction to me‚ other people who I work with‚ or people passing who may be injured. After taking these measures into account‚ I was able to

The Thickness of Aluminum Foil Lab In the study of Chemistry‚ we encounter very large and very small numbers. For example‚ the size of a molecule or thin layer of molecules is very‚ very small and difficult to measure directly. In order to “measure” such numbers‚ we often use one measured quantity and another known property to calculate the unknown value. In this experiment‚ we will use this approach to calculate the thickness of various types of aluminum foil‚ a quantity whose direct experimental

1. Objective: The objective of this experiment is to demonstrate the bending of a bean when loaded at the center of its length and examine its deflection when positioned in two different ways‚ when the flat side of the beam is support and when the thin side is supported. In addition‚ try to find linear relationship between the load applied and the deflection of the beam and comparing the experimental deflection with the theoretical deflection. If the load is applied at the mid- length a=b=L/2

nature is. Out of all the possible literary works that have a theme about nature there’s three in particular that are going to be described in this essay. These three works are "A Description of New England‚" by John Smith‚ "Rip Van Winkle‚" by Washington Irving‚ and "Thanatopsis‚" by William Cullen Bryant.
