Biochemistry CP2085 Effect of Temperature‚ Study and Measure of Enzymes Activity Abstract This experiment investigates the effect that temperature has on the rate of activity of enzyme β-galactosidase and also the rate of β-galactosidase activity in different concentration of substrate over time. Ο-nitrophenylgalactoside (ONPG) is used as a substrate for β-galactosidase. A spectrophotometer is used to detect the change in colour of the substrate. Results show that increase in temperature up to 50oC speeds

Temperature and Thermometers The Temperature of an object is a measure of the hotness or coldness of that object. An alternative way to think of temperature is to say that “the temperature of an object is a number – on some manmade scale – that indicates the hotness of the object”. ‘Hotness’ in turn is a measure of the kinetic energy of the molecules of the material. Note: You must use the term ‘hotness’.* The SI unit of temperature is the Kelvin (K)* Relationship between degrees Celsius

Diffraction and interference describe effects unlike what geometrical optics would predict: the edges of shadows are not quite sharp; the beam passed by a slit is not a narrow rectangle. Diffraction patterns carry information about the spacing and location of the elements in the diffraction grating that produced them. Conversely‚ if we know the structure of the grating‚ we can deduce properties about the incident light‚ in particular its wavelength. This will be our task‚ in this first optics

Physics (Thorpe Park Trip) Report: On Monday 8th October our physics class went on a physics trip to Thorpe Park to look at the different ways in which a roller coast works. This report will be looking at the G forces acting on rides‚ the launching systems and breaking systems. The particular rollercoaster which I have picked to look into more detail in is “Stealth” which is located in Thorpe Park. Stealth: Stealth was originally designed by Werner Stengel. Stealth reaches a height of 205 feet

Extension: The Physics in Swimming Physics is defined as the branch of science concerning the study of matter and energy and the interactions between the two. Physics tries to explain the nature of the world around us‚ how things happen and why. Swimming displays some physical properties‚ such as buoyancy‚ drag resistance and propulsion. We swimmers are at a constant battle to stay afloat‚ while fighting through the water and propelling ourselves forward‚ and we do so using technique. Buoyancy is the power

What is Physics? Physics is a field of science that shows the interaction between matter and energy. It shows physical processes that help us understand better how our universe behaves. Physics also use scientific method that formulates and tests hypothesis which are based on observations and comprehensions. What are the different fields under Physics? PHYSICS PHYSICS dealing with physical processes and their relations in the science of physical chemistry. dealing

Physics (from Greek)‚ i.e. "knowledge‚ science of nature"‚ from φύσις‚ physis‚ i.e. "nature"[1][2][3][4][5]) is a part of natural philosophy and a natural science that involves the study of matter[6] and its motion through space and time‚ along with related concepts such as energy and force.[7] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[8][9][10] Physics is the field of science that studies the physical world.

Physics Formulas: Mechanics Mechanics is the oldest branch of physics. Mechanics deals with all kinds and complexities of motion. It includes various techniques‚ which can simplify the solution of a mechanical problem. Here are some of the often required physics formulas falling in mechanics domain. Motion in One Dimension The physics formulas for motion in one dimension (Also called Kinematical equations of motion) are as follows. (Here ’u’ is initial velocity‚ ’v’ is final velocity‚ ’a’ is
