EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

The Milgram Experiment Stanley Milgram‚ a famous social psychologist‚ and student of Solomon Asch‚ conducted a controversial experiment in 1961‚ investigating obedience to authority (1974). The experiment was held to see if a subject would do something an authority figure tells them‚ even if it conflicts with their personal beliefs and morals. He even once said‚ "The social psychology of this century reveals a major lesson: often it is not so much the kind of person a man is as the kind of situation

Abstract The Tuskegee syphilis experiment was an infamous clinical study conducted between 1932-1972 in Macon Country‚ Alabama by the U.S Public Health Service. The purpose was to study the natural progression of untreated syphilis in rural African American men who thought they were receiving free health care from the U.S government; about four hundred African American men were denied. The doctors that were involved in this study had a shifted mindset; they were called “racist monsters”; “for
