Road Safety Lab Report Research Question: How is the stopping distance affect by the surface area of an object? Variables: Independent variable: The Different Surface Area (0cm2‚ 1760cm2‚ 2480cm2‚ 3440cm2‚ 3920cm2) Dependent variable: Stopping Distance Controlled variables: Mass of Object Environmental Conditions (Hallway Atmosphere) The surface of the road (Marble) The type of wheels (plastic) Height of the Ramp Background Information: The aerodynamics of an external object

Friction on a surface. Aim: To establish the relation between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance Materials required: A rectangular block of wood with a hook ‚ set of weights‚ strong thread and a spring balance. Theory: The force of friction acting on a block of wood is proportional to the normal reaction acting on the block. By the third law of motion‚ normal reaction is equal to the weight

only to Van der Waals forces that operate by induced polarity in non-polar molecules. Cohesion‚ along with adhesion (attraction between unlike molecules)‚ helps explain phenomena such as meniscus‚ surface tension and capillary action. Mercury in a glass flask is a good example of the effects of the ratio between cohesive and adhesive forces. Because of its high cohesion and low adhesion to the glass‚ mercury does not spread out to cover the bottom of the flask ‚ and if enough is placed in the flask

Structure of Gaseous Exchange Surfaces in Humans‚ Fish‚ Insects and Frogs Gaseous Exchange is a biological process where oxygen diffuses into the body or bloodstream and carbon dioxide diffuses out of the body or blood stream. This process is different for Humans‚ Fish. Frogs and Insects. Humans: In humans the gas exchange system is known as the Respiratory system. The respiratory surface is the Alveoli located on Bronchial tubes inside of the lungs. The average human adult has about 600 million

Ratio Analysis Memo July 9‚ 2012 Memo To: From: Date: July 9‚ 2012 RE: Kudler Fine Foods ratio analysis One of the things that we will be going over is some of the ratios for Kudler Fine Foods through Liquidity‚ Profitability‚ and solvency ratios. We will look into some of the finding that were found through these ratios and discuss them. One of the things that we found was where Kudler Fine Foods’ position is with these ratios. The first area that we look at is profitability

Surface Tension My problem was to find out how to test or measure surface tension. I think the reason of some of the force in surface tension is cohesion and gravity. Surface Tension is the condition existing at the free surface of a liquid‚ resembling the properties of an elastic skin under tension. The tension is the result of intermolecular forces exerting an unbalanced inward pull on the individual surface molecules; this is reflected in the considerable curvature at those edges where the

Microsoft’s Surface Pro laptop-in-disguise1 tablet is no different‚ a “flawed”2 device which has seen improvements to its design and structure over the past few years making it slowly approach perfection. Microsoft’s Surface Pro is one of the newer innovative devices that was initially introduced in February 20133 and has seen a much shorter succession cycle than that of any other popular tablet manufacturer‚ namely Apple. Adoption rate was not at its best with the initial introduction of the Surface Pro

Adsorption: The accumulation of molecular species at the surface rather than in the bulk of a solid or liquid is termed as adsorption. Adsorbate: The substance which is being adsorbed on the surface of another substance is called adsorbate. Adsorbent: The substance present in bulk‚ on the surface of which adsorption is taking place is called adsorbent. Desorption: The process of removing an
