Circular Motion and Gravitation Centripetal Acceleration and Centripetal Force 1. What is the centripetal acceleration of a point on the perimeter of a bicycle wheel of diameter 70. cm when a bike is moving at 8.0 m/s? 2. A pilot is upside down at the top of an inverted loop of radius 3.20 x 103 m. At the top of the loop his normal force is only one-half his normal weight. How fast is he going? 3. The maximum force a pilot can stand is about seven times his weight. (This is his

Whilst Boyle Family are best known for their random studies of the surface of the Earth, other aspects of their work are now getting increasing attention following their retrospective at the Scottish National Gallery of Modern Art in Edinburgh last year. A highlight of the exhibition was a video room devoted to a selection of Boyle projections from the 1960s, which are being shown in London for the first time since 1969. In the late 1950s Mark Boyle and Joan Hills set out to make an objective examination

Measurement of the moment of inertia of a flywheel A flywheel of radius R is set up on a horizontal axle of radius r. A string of length h is wrapped round the axle with a mass m tied to the end (Figures 1 and 2). The moment of inertia of the flywheel and axle is I. The flywheel is accelerated by the couple applied by the mass m. The mass is allowed to fall through a height h at which point the string leaves the axle. The velocity of the falling mass at this instant is v and the angular velocity

problem lies in the fact that no two humans are the same therefore reaching a unanimous decision on what human nature is, is near enough impossible. Over the years three ideologies have emerged as the leading theories on human nature; conservatism, classical liberalism and Marxism. The three have their own differing views on what the basis of human nature is. These ideologies have evolved into political parties and their policies are largely influenced by their views on human nature. This essay will

Classical Conditioning Classical conditioning theory involves learning a new behavior via the process of association. In simple terms two stimuli are linked together to produce a new learned response in a person or animal. There are three stages to classical conditioning. In each stage the stimuli and responses are given special scientific terms: Stage 1: Before Conditioning: * In this stage, the unconditioned stimulus (UCS) produces an unconditioned response (UCR) in an organism. In basic

This problem emphasizes the fact that even if we have two different charges, mutual electrostatic force between them will be same. 1.8 Coulomb’s Law in Vector Form As force is a vector quantity, it has some magnitude as well as direction. We will write coulomb’s law in vector form so that it will represent magnitude as well as direction of electrostatic force. Consider two charges q1 and q2 separated by distance r. First of all we will define . It is the vector joining charge q1 and q2.

I have been hoping to develop my career path in music industry since childhood. I determined to be successful in this industry. There are hundreds of people who became very successful and one of them is Ludwig van Beethoven. According to Jane S. Van Ingen (n.d.), "By the time Beethoven was 40 years old in 1810, he had given the world six symphonies, 15 piano sonatas, 10 quartets, five concertos, a ballet, an opera and a choral mass" (para. 1). Beethoven is one of the greatest masters in music composition

In its most general sense, Behaviorism, also known as behavioral psychology, is a theory of learning developing as a result of the propositions and beliefs shared by a group of people who has influenced educators’ view of learning. The term behavioral psychology refers to a psychological approach which principally concerned with stimulus-response activities and emphasizes the role of environmental factors in a learning process, to the exclusion of own free will. There is a tenet of behavioral psychology

music as "classical" as opposed to "folk" in the European context? How has "classical" music influenced "folk" music style and performance and vice versa? In the European context, classical music is the highest class of music. Folk is a position relative to classical music. Folk music was meant for the common people. It was the opposite of classical music. Folk played classical music and folk music started to interest higher class people. They wanted to become part of a tradition. Classical music started

Homework Week 3 September 22, 2013 DeVry University Online Operant conditioning sometimes referred to as instrumental conditioning is a method of learning that occurs through rewards and punishments for behavior. Through operant conditioning, an association is made between a behavior and a consequence for that behavior. A good example of Operant conditioning is: employees finishing projects to receive praise or promotions (Cherry, 2013). Observational learning occurs when one observes another’s
