Purpose Determine the acceleration in a quick sprint. Question What would the participant’s acceleration be if he/she sprints forward in a positive direction? Hypothesis/Prediction When a person sprints forward‚ it means he/she speeds up. Consequently‚ the acceleration should be positive. When the velocity accelerates at a constant rate‚ the acceleration should remain constant. Therefore‚ if the participant is moving toward a positive direction and the speed increases‚ then the acceleration

AIM: Finding the gravitational field strength by using a simple harmonic motion of a spring and slotted masses. INTRODUCTION: When a mass suspended from a spring is displaced‚ due to the acceleration‚ kg s-2‚ from its equilibrium and released it will oscillate up and down with a kind of motion called simple harmonic motion‚ shm. The period (T)‚ time taken to measure for one complete oscillation‚ of this motion is: m/kg =

A 1.00 x 10²g mass of tungsten at 100°C is placed in 2.00 x 10²g of water at 20.0°C. The mixture reaches equilibrium at 21.6°C. Calculate the specific heat of tungsten. Cw = 4180 J/kg°C C= 171 J/kgOC 3. A certain metal has a specific heat of 400 J / kg oC. It absorbs 8000 J of thermal energy which causes its temperature to raise 10oC. How much mass of the metal

FORMAL REPORT ON HEAT CAPACITY RATIOS OF GASES ABSTRACT This report discusses an investigation of the heat capacities of Helium‚ Nitrogen‚ and Carbon Dioxide. To accurately determine experimental values for the heat capacity of each gas‚ the heat capacity ratio was calculated from measurements of the speed of sound in each gas. An apparatus designed to measure the wavelength and frequency of sound waves in each gas was used to determine the speed of sound as a frequency was passed through each

UNSTEADY STATE HEAT TRANSFER Heat transfer processes are prominent in engineering due to several applications in industry and environment. Heat transfer is central to the performance of propulsion systems‚ design of conventional space and water heating systems‚ cooling of electronic equipment‚ and many manufacturing processes (Campos 3). Unsteady state conduction is the class of heat transfer in which the temperature of the conducting medium varies with time and position. This occurs frequently in

PHYS 221 Experiment M10 Harmonic Motion of a simple Pendulum Jacob LaMarre Group members: Josh‚ Courtney‚ Ashley Abstract: Determine the acceleration due to gravity using a pendulum. Introduction: A simple pendulum consists of a mass suspended by a length of string. When set Oscillating‚ the mass will have a period “T” given by the following equation. This equation shows the only variables that affect the rate at which the pendulum swings is the length “l” that is measured to the center

Diffusing Capacity Tests Diffusing capacity test it’s done to measure the lung’s ability to exchange gases through alveolar-capillary membrane by using gas mixture. In this test they assess 3 things to see the efficacy of the lung; 1- Lungs’ surface area with contact diffusing alveoli which is "alveolar volume". 2- Thickness of alveolar-capillary membrane. 3- blood volume available in the pulmonary capillaries. Physiology: In normal lung the gas exchange occur by passive diffusion of the gas via
