To solve a mechanics problem, you should read the problem carefully and attempt to relate it to theories you’ve learned. Draw accurate diagrams and write out the problem data. Next, apply physical principles you have learned such as Newtons Laws, and tabulate mathematical equations. Double check to make sure your equations are dimensionally homogeneous: a fancy way to say that they have similar units on either side of the equals sign. Solve your equations and check your solution if possible. […]
In a wave energy can move from one place to another, however the actually matter particles will return to its original place (1). The waves however don’t go back to their original place but go to their desired location (2). The reason why the transport of matter doesn’t exist is because you would need other matter to move or other matter to have a force which would cause the other object to move (1). The differences between transverse and longitudinal […]
The scientific method refers to group of steps that investigate phenomena, acquiring new knowledge, changing or correcting prior knowledge. The scientific method is used by all scientists all around the world. It’s a way for researchers to find cause and effect in experiments. The first step to the scientific method is asking a question. This process is the reason for the experiment or discovery. It usually involves who, what, when, where. Which the whole process of the scientific method will be nearly based […]
Practice Journal—Dave Berry, “Red, White, and Beer” Recapping: In the beginning of “Red, White, and Beer”, Dave Berry is talking about how commercial are very patriotic and pro-American. Then, he goes on and gives examples of commercial that show pro-America like Chrysler with the winner of the Bruce Springsteen Sound-alike contest. Dave gets more specific on how beer commercials show the most pro-America, especially Miller. Dave also explains how Miller’s commercials have these burly American men who go round and […]
Objective: To determine the reaction order with respect to crystal violet and determine the rate constant and half life for the reaction: [CV+ + OH– Þ CVOH]. Procedure: (1) Calibrate the Colorimeter with distilled water. (2) Prepare a solution with 10ml each of the provided CV and OH. (3) Let solution stand for 3 minutes before beginning (4). (4) Place solution in Colorimeter and record data point with software. (5) Remove solution for one minute. (6) Repeat steps (4-5) twenty […]
