I measured and marked 3cm from the bottom of a small test tube. I filled the tube to 3cm marked with our assigned pigment solution. I then turn on our spectrophotometer and I loaded it with a test tube filled with distilled water into the slot in the machine and closed the lid. I then pushed the test button I pushed again the stored tests option and I pushed load test (chlorophyll). I pushed run test and then I pushed tabular.
Incisions are made behind the opercula to form a flap. Three thin slices (0.3 cm) of muscle and cartilage are consecutively removed from the head until three pea-shaped structures are revealed in a cavity. The brain is removed from the cavity by gently probing and scraping it out with a scalpel. Finally, the eye is removed from the socket by means of protruding a finger through the gills and loosening the muscles around the eye and it is pushed out from the socket. From the outside the eye is gently pulled away from the head to detach it completely from the
Sketch what you see. Measure your craters and record any observations. Repeat steps 3 and 4 with the large marbles. Continue the experiment, dropping the marble from heights of 30 cm, 1 m, and 2 m. Make sure you continue to record your observations, sketching what you see and measuring the crater sizes. Observations Variable Observations Size of “rock” Trial #1 Trial #2 Trial #3 Small (Dropped from 30cm) Marble fell near the surface.
As the parachute falls, these two forces are almost in perfect balance, the drag force that comes from the parachute is slightly less than the force of gravity, this lets the parachute fall safely do the ground. As parachutes are used for when people go sky-diving, this experiment has been conducted multiple times for skydivers. It has been found that this relates closey to Issac Newton’s Laws of Motion, especially his first. His first law clearly states that if forces on a object are in balance, that specific object’s speed and direction (of motion) will not change throughout. So, if the object is moving, it will continue to do so in a constant speed and straight line.
Equipment: • Different coloured pens/textas • Filter paper • Scissors • 250ml beaker • Pencil or pop stick • Tape • Water Methylated spirits Ruler • Measuring cylinder Method 1. Cut a 10cm length of filter paper 2. Rule a line in pencil 2cm from the bottom end of the paper 3. Place a mark on the pencil line with two of the pens/textas 4. Add approximately 25mL water to the beaker 5.
Airfoil Terminology, Its Theory and Variations As Well As Relations with Its Operational Lift Force and Drag Force In Ambient Conditions Author Names: Dr V.N. Bartaria (H.O.D Mechanical engineering LNCT Bhopal) Shivani Sharma (B.E. Mechanical engineering Pursuing M.tech) Abstract: It is a fact of common experience that a body in motion through a fluid experiences a resultant force which, in most cases is mainly a resistance to the motion. A class of body exists, However for which the component of the resultant force normal to the direction to the motion is many time greater than the component resisting the motion, and the possibility of the flight of an airplane depends on the use of the body of this class
III. Turbulent Flow • Valve 1 and 3 should be closed now and only valve 2 should be open now. • Using stop watch and beaker measure the flow rate again 4-5 different times. IV. Calculations • Calculate the velocity (m/s) and the Reynolds’ number for each flow rate.
I numbered these strings 1 (m. 93), 2 (mm. 94–95), 3 (mm. 96–98), and 4 (mm. 99–103). It uses the minimalistic compositional device of note addition and subtraction by splitting each of the strings in half and filled in with new—but related—material by the next string.
Quickly the serum was acclimated to 0.75m Sodium sulfate and 3 volumes of Affi-T gel was included under tender shaking at 200c. following 1 hour the gel was washed three times with three volumes of 0.75m Ammonium sulfate precipitation and the ensuing arrangement was conformed to the first volume as depicted above (Honge et.al., 1994). 2.18.2 Non-Chromatographic
