Molar mass distribution

Therefore, any problem that can be solved by the work-energy method can, in theory, be solved using the FMA method. There is main advantage of using work and energy method compared to the force-mass-acceleration (FMA) method. 1. Work can be calculated in problem without integration, the change in speed of the particle may be easily obtained with a minimum of computation. 2. Only forces that do work need to be considered which mean a nonworking…

When teaching the skill of sweeping or brushing to novice curlers necessary to always remember the three basic fundamentals. These fundamentals are body weight, brush speed and footwork. Throughout the process of teaching our skill we will continue to highlight these fundamentals ensuring that our teens will remember them and hopefully demonstrate them as they continue to curl. During our teaching of the skill it is important to note that we will always be watching for unsafe practices on the…

formed or impaired; it’s always preserved. Potential energy is a kind of spared energy that objects have because of their position or configuration. Energy comes in many forms, and can be converted from one form to another. Kinetic energy is energy of mass in motion, and the formula is E=1/2mv^2. The most important property of kinetic energy in the ability to do work, and it can be transferred from one body to another in collision, which can be elastic or inelastic. Joule found out about Energy…

Introduction Section- The purpose of this experiment is to use reaction stoichiometry to determine the molar mass and the identity of an unknown, powdered metal, and to identify an unknown metal nitrate solution. To give a little background information on this experiment I will start by saying that a balanced chemical equation provides several important pieces of information about a chemical equation. Those important pieces include the substances consumed and formed, the physical states of the…

Weight Watchers can be a system developed to assist participants shed weight. The particiapnts of the system are permitted to purchase and cook their very own food options and so the program differs from other individuals. It has been proven to be efficient and is an excellent diet plan option for all those who want to shed fairly a little of weight and for all those who could just have a few additional pounds that they would like to become rid of. Weight Watchers also has a separate plan for…

Lab 3: Technology Name: Section: General Physic Lab 3 Date: 10/03/2017 Purpose The goal of this experiment was to learn how to apply computerized instruments in physics. In addition, this experiment aimed at enhancing practice on how to use three equipment in the lab: the rotary motion sensor, high resolution force sensor, and motion sensor. Further, this experiment sought to clarify the circumstances under which the instruments fail to comply with expectations. Results/Data Part 1: The…

“Hey, can you pass me the popcorn?” Katherine asked “Sure! Haven’t you had enough though Kat?” I replied jokingly. Kat was my nickname for her. My nickname was ______. “Nope!” Kat replied grinning like a clown. I passed her the popcorn and replied with a smile, “Alright, suit yourself.” We had been in my large basement the whole day binge watching television shows and movies on Netflix. Kat and I made a drawer in one of my closets filled with junk food and sweets back in middle school. It…

John Ortiz is a recent a graduate from a highly touted dance academy. In his last semester at the academy, one of his instructors was interested in what had driven her students to find their passion in dance. So to find out she gave an assignment for each student to write a paper on how they fell in love with dance. In John’s case, falling in love with dance seemed as likely as the Cleveland Browns ever winning the Super Bowl. Growing up John was never the most slender kid. He always had a big…

the Acceleration and gravity is the same because it was dropped and not thrown which means that the speed it will fall will be 9.81 m/s. By combining all of the data, the egg speed was found, it was 9.81 m/s identical to gravity, also, the vessel’s mass, and the density of the object was very light and was able to protect the egg and leave it without a…

The Magnet Cannon is a perplexing object to understand how the forces work, in this explanation I will explain how the forces and energy in the magnet cannon work. The purpose of the magnet cannon is to help show how kinetic and magnetic forces work. The magnet Cannon is an object composed of 5 balls a ruler and a magnet. One of the balls is placed on one side of the magnet (ball A), then the other 4 balls (balls B-D) go on the other side of the magnet, then the contraption is placed on a ruler.…
