Dancers do not often understand the physics and mathematics describing their movements‚ but they know how to execute them with grace. If ballerinas were not able to feel physics‚ they would fall over. Legs‚ arms and head are oscillating as they turn– moving back and forth in seemingly separate patterns. For dancers‚ everything must move in separate patterns‚ yet at the same time‚ move at the same rhythm. This presentation introduces the history‚ mathematics‚ and physics behind ballet. Ballet originated

Introduction Background Theory The usual equation for measuring electric current flowing through a series is I = V/R. The current flowing in a series is affected by the voltage and the resistor that is also creating the series. Electric current is a flow of electric charge through a conductive medium. These charge is in a form of moving electrons in a wire. The SI unit for electric current is ampere (A) and can be measured by using a device called ammeter. Change in temperature can change

HOW DO WE WRITE THE RESEARCH PAPER? A science investigatory project ends with a report. It is also known as the technical paper. OUTLINE FORM A. TITLE - catch the attention - concise - accurate - descriptive - self-explanatory The phrase “A Study to Show” should be avoided‚ because in research you do not seek to prove something‚ but rather to impartially find an answer. B. ABSTRACT - short paragraph of not more than 200 to 250 words - gives the essential or principal features of

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

Test 01 - Introduction Receptor cells use chemical transmitters to communicate with relay cells or afferent nerve fibers. In all sensory systems‚ accessory structures modify‚ in some way‚ the stimulus going to the receptor surface. Receptors are electrically polarized cells and therefore have a resting membrane potential. Stimuli produce‚ in the appropriate receptors‚ a change in the electrical properties that is known as the receptor or generator potential. The two ways in which sensory stimuli
