Burn‚ Baby‚ Burn: Comparing the burning speed of scented and unscented candles This experiment was performed to compare how quickly a scented and an unscented candle will burn. The tests were done by comparing the length that the candles will burn in 30 minutes - using unscented‚ rose scented and apple scented candles. Hypothesis: Unscented candles burn more quickly than scented candles. Overview: Candles Candles are a convenient way of providing light and heat when no electricity is available

will still move a certain distance known as the” breaking distance”. The table below shows the breaking distances that were obtained at different speeds: If we show the relationship of the speed and the breaking distance by plotting a graph like this one: If we want to get an equation that helps us identify the relationship between the Speed and the breaking distance. We can see that the line makes a form of a parabola so we drive it through out calculator to get the following results:

3.3. Slowing Down The Error Propagation Speed In this section‚ we will explain the studies that made for slowing down the error propagation. In this project‚ we will attack this research problem from multiple angles. First‚ we will consider different algorithms and gauge whether such choices have a significant impact on error propagation profiles. Second‚ we will consider compiler optimizations that slow error propagation. 3.3.1 Impact of the algorithms Error propagation behavior is connected with

Characteristics and Walking Speed The data gathered from 4 to 5 individuals pertaining to their walking speed was documented in 5 different instances and an average taken to gain a clearer picture of a relationship between the average walking speed of an individual and the impact of physical characteristics between individuals‚ on walking speed. 1. INTRODUCTION In observing individuals in daily routines‚ it appears that height‚ and weight affects the walking speeds of individuals in different

then the speed of sound will also increase because faster-moving particles transfer energy quickly. The data collected supports the hypothesis. Therefore‚ increased air temperature affects the speed of sound because the molecules move faster‚ which causes the energy to be transferred quickly‚ which then increases the speed of sound. In the data‚ when the temperature is increased by 10°C‚ the speed of sound increases by 6 m/s. For example‚ the speed of sound at 0°C is 331 m/s and the speed of sound

The effect of caffeine on typing speed‚ accuracy and heart beat 1. Introduction Caffeine is a substance found in coffee‚ tea and most sodas. When it is consumed‚ it is a mild stimulant. The energy drink‚ Monster‚ contains caffeine‚ which has the ability to manipulate adenosine (adrenaline)‚ a substance present in the brain that is used to transmit brain signals to different parts of the body. Adenosine causes an increase in alertness and awareness. Modern studies show that there is direct benefits

Speed of the Human Neural Impulse Helmholtz (1821-1894) was a German scientist. In 1850‚ he measured the neural impulse in frogs. By strapping down the frogs and putting electrical voltage into their legs‚ Helmholtz measured the time it took for the frogs’ leg to twitch. Helmholtz used a galvanometer to measure the neural impulse. He found that the neural impulse in frogs was 83-90 ft/s. Afterwards‚ Helmholtz went on to test the neural impulse in humans. He put a low grade electrical voltage to humans’

TITLE CONTACTLESS TACHOMETER ABSTRACT: The aim of the project is to design a contactless speed sensing device (tachometer) for a motor. Traditional tachometers require a physical contact to the shaft of the motor to measure the speed. In certain applications‚ where it is not possible to measure the speed directly‚ it is possible for a contactless tachometer to take the readings from a certain distance. This is the main motivation behind choosing this project. This contactless tachometer
