subsequent stimulus? It gets higher. Activity 5: Investigating Wave Summation 1. Is the peak force produced in the second contraction greater than that produced by the first stimulus? yes 2. Is the total force production even greater?yes. 3. In order to produce smooth‚ sustained muscle contraction at Active Force = 2 gms‚ do you think you will need to increase or decrease the voltage? State your hypothesis.decrease. 4. Test your hypothesis. At what voltage were you able to achieve Active Force

gradations while th sliding scale (vernier scale) has 0.05 mm gradations. The smallest division of vernier scale is called the least count of vernier caliper. It may be different for different vernier calipers (and other measuring instruments). In order to measure length‚ put an object between the jaws and close the jaws gently. Fix the object with the fixing screw. (Fig.2b) In Fig. 2b‚ the leftmost thick mark on the sliding scale is between

Design Lab – “The Rotocopter” Title – The Effect of Weight on the Time it takes for the Rotocopter to Fall Down Introduction – In this lab or experiment‚ we looked for variables that affect the falling motion (how long it takes) of a structure called a rotocopter. The purpose was to see and find out how the weight of the increasing number of paper clips attached (independent variable) would affect the time (dependent variable) it takes for the rotocopter to spin down from

In November 1994‚ John Wells‚ a customer service representative of Bayfield Mud Company‚ was summoned to the Houston warehouse of wet land Drilling‚ Inc.‚ to inspect three boxcars of mud-treating agents that Bayfield Mud Company had shipped to the Houston firm. (Bayfield’s Corporate Offices and its largest plant are located in orange‚ Texas‚ which is just west of the Louisiana-Texas border.) Wet-land Drilling had filed a complaint that the 50 Pound bags of treating agents that it had just received
