Since the mass of the plate is a uniform‚ the center of mass is in the center of the plate. The plate has diameter d = 28 cm‚ thus the center of mass is 14 cm from the edge of the plate. In the lab‚ two scenarios will be analyzed; 1) when the glass is standing up‚ and 2) when the glass is laying on its side. When the glass is standing up‚ its mass

Introduction The purpose of this lab is to examine the motion of an electron‚ when it encounters a constant magnetic and electric field. We will also observe when the electric field and magnetic field will cancel each other out. This will lead to the electron having no net force acting upon it. By adjusting the values for the magnetic and electric fields‚ we will be able to check the different paths the electron follows. From this data we will be able to calculate the charge-to-mass ratio. Then

An investigation into the specific heat capacity of a solid Introduction: In this experiment I investigated the specific heat capacity of brass and aluminium‚ in order to do this I arranged a series circuit with a heater‚ the heater would go inside the brass and aluminium and heat it for an amount of time in which I decided‚ I also used the voltmeter in parallel. This arrangement made me able to arrange the equation VIT= mcΔθ‚ since the electrical energy in would be equal to the mass times the

The first thing everyone should do after sitting in their car is buckle their seat belts. Too many unnecessary loses of life occur each year for the simple reason people just do not wear seat belts. It is a confirmed fact that using a seat belt saves lives and prevents serious

Circular motion‚ gravitational field‚ and oscillation 1.Define gravitational field strength: Force per unit mass 2. Explain why there is a point between two point masses at which the gravitational field strength is zero. Because gravitational fields of two masses are in opposite directions‚ so there is a point where it is zero What is meant by angular velocity The rate of change of the angular displacement of an object as it moves along curved path. Generally when asked to test

The Importance of Automobile Safety Many people‚ including college students‚ overlook one of the most important things when buying a new car–safety. It is a known truth that a new car is probably filled with the most up-to-date safety features in the automotive market today. However‚ knowing that the car is “safe” does not mean how safe the car really is because of the safety features it has or the lack of them. Therefore‚ this paper will illustrate the need to examine and research the safety features

was driving a car and got into a serious wreck and the air bags did not deploy therefore injuring the victim then they could sue the automobile company for money‚ a new car‚ pain and suffering‚ etc. Some of these safety features include Brakes‚ Airbags‚ seat belts‚ and more. When talking about brakes in a car you’re going to want to know what it is your getting because there are many different options in brakes‚ some examples of this being your regular brakes like you push down the peddle softly
