nucleus but they do not react as radioisotopes do. These factors are categorized by the extra energy which is present in them and which would be used to react and produce some other particle. The reaction, which would result in various emissions of Gama, rays, alpha particles, beta particles. The reaction, which causes these emissions, is called radioactive decay (Radioactivity). The discharge of the radioactive decay is harmful in various ways, only due to the progress in technology now these disadvantages

Cloud Chambers were used to detect ionization particles. Cloud Chambers are sealed environments with super saturated liquid such as water or alcohol. The liquid is allowed to vaporize in the chamber. This vapor forms a mist in the sealed chamber. Any cosmic particle, such as a alpha or beta particle, ionizes the mist and forms a ionized nuclei. This nuclei form causes the mist to condense around it and form a cloud. For our chambers we used donated peanut butter jars that were cleaned out. These jars

Name Instructor Course Date Dark Nebulae Dark nebulae are nonluminous nebulae that are observable since it obscures light from other sources. Nebulae are diffuse clouds of interstellar dust and gas. The shape, size, and characteristics of nebulae may vary significantly because some are the remains of dead stars and others are star nurseries. Dark nebulae are found in areas with no nearby stars. These clouds do not emit or reflect enough light for them to be visible. In fact, the view from the stars

Questions A. How did the angle of incidence compare with the angle of reflection? B. In trial 5, you aimed the incident ray directly along the normal. Describe the path of the incident and reflected rays for this special case. C. Where might errors occur in this activity? D. How would these errors affect your conclusion? E. Billiards is a game that makes use of reflection (Figure 2). How could the results of this activity help you in such a game? F. What other sports or activities make

concave surfaces; and to measure the index of refraction of water. Theory: If a ray of light is incident on a flat surface: the angle of incidence a is the angle that the incident ray makes with respect to the normal, which is a line drawn perpendicular to the surface at the point of incidence. The angle of reflection r is the angle that the reflected ray makes with the normal. The incident ray, the reflected ray, and the normal to the surface all lie in the same plane, called the place of incidence

dots in the centre of the incident and reflected rays. Move the mirror to one side and use the ruler to join the dots to show the complete path of the ray. Add arrows so you know which direction the ray travelled. At the point where the ray reflects from the mirror add a line perpendicular to the mirrors surface - this is the normal line. Use the protractor measure the angle between the normal and the incident ray, and the normal and the reflected ray. Note these angles in a table and then repeat

Cultural Diversity in Professions 11-13-2010 You Decide Out of the four applicants for the sales manager position, one applicant stood out from the rest as better prepared to fulfill the job description. All applicants possessed particular qualities or characteristics that were fitting for the position, however, only one of them had both the experience, and knowledge the position requires. As a human resource manager I would hire Karen for the job. The reason why I would hire Karen for this

the incident ray would be directed towards the mirror and the reflected ray would match the incidence ray but would reflect the other way. For example, when trial 1 was performed and the angle of incidence was aimed on the plane mirror, its angle equaled 45°. The angle reflected off the mirror in the same angle which also equaled 45°. This reflection came off a smooth surface which was a flat mirror. This reflection is known as a specular reflection. b) In trial 5, when the incident ray was aimed
