reaction rate of enzymes in different environments. Second part of the experiment was performed to see the effect of substrate concentration on velocity of the reaction. Different level of ADP or substrate was used and corresponding OD510nm reading was measured. Both Michaelis-Menton Plot and Lineweaver-Burk plot were constructed to determine maximum velocity‚ Vmax and Michaelis constant‚ Km. Vmax is a maximum rate at which the enzyme can perform the reaction and Km is an inverse measure of the affinity

distance it traveled2‚3. The formula for determining kinetic energy is KE = mv2‚ where KE is kinetic energy‚ m is mass of the projectile‚ and v is velocity. Based on this formula‚ the velocity of a projectile has traditionally been considered far more important than its mass in determining its wounding power. Indeed‚ guns are often classified according to velocity as

propagate in a wave medium‚ such as sound waves‚ the velocity of the observer and of the source are relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from motion of the source‚ motion of the observer‚ or motion of the medium. Each of these effects is analysed separately. For waves which do not require a medium‚ such as light or gravity in special relativity‚ only the relative difference in velocity between the observer and the source needs to be considered

produces a greater velocity increase above the wing than below the wing. The greater velocity increases the pressure differential on a cambered airfoil. The greater pressure differential on the airfoil will increase the magnitude of the aerodynamic force. SYMMETRIC AIRFOIL Increasing angle of attack on any airfoil causes the area of the streamtube above the wing to decrease. This produces a greater velocity increase above the wing than below the wing. The greater velocity creates a pressure

changes its velocity. An object is accelerating if it is changing its velocity. People will occasionally say that a person is accelerating if he/she is moving fast. Yet acceleration has nothing to do with going fast. A person can be moving very fast and still not be accelerating. Acceleration has to do with changing how fast an object is moving. If an object is not changing its velocity‚ then the object is not accelerating. Sometimes an accelerating object will change its velocity by the same
