INTERPRETATION OF RESULTS: This experiment circles around with the Newton’s second condition of equilibrium in rotational motion. It describes by net torque acting on a body which is zero. The ability of the body to rotate in a certain direction is varied according on how much torque is applied. To prove that‚ a beam that is subjected to two forces is balanced by adjusting the perpendicular distances. When applied force is weight‚ modification in masses added is also done. Once equilibrium is achieved

hypothesis was that EDTA will remove the ions‚ and will not work. Materials/Methods For unit 7.3 the experiment needed 2 microfuge tubes one labeled "L" for lactose and the other labeled "M" for maltose. The experiment also called for a total of 3 clean plastic pipettes. With one pipette add milk up to the 0.5 line of the lactose tube. With the second clean pipette add maltose solution up to the 0.5 line of the maltose tube. With the third clean pipette‚ add lactase solution to each tube‚ until

ionise to provide a conductive path for the current. Consequently this phenomenon might damage the contacts of the switch over time. (We assume that the switch used in this circuit is rated at only 100 Vdc). FIGURE 3 From Figure 3: A diode in series with a resistor is connected across the inductor to resolve the arcing phenomena across the switch. At t 0‚ when the switch is opened‚ the diode is forward bias hence allowing current to its branch. The current‚ I in
