Calculation of conduction velocity Distance between recording electrodes: 30 mm Time interval between CAP1 and CAP2: 0.53 ms Conduction velocity 56.60 m/s Based on your calculation for CAP conduction velocity, how long would it take the CAP to travel the length of the sciatic nerve? Assume a total length of 100 mm.
Give me additional examples of values with infinite significant figures. According to our handouts, here is one of the examples: 3000 chocolate Bars which are considered countable numbers. Moreover, the final zeroes in a whole number are significant IF the unit of quantity is measurable like mass, temperature, length, current etc. Therefore, even the trailing numbers are counted as significant. Example: 40 kg (2 sig figs) & 1900 mm (4 sig figs). Give me more examples as well. Thank you!

The immediate cause of many deaths is ventricular fibrillation, an uncoordinated quivering of the heart, as opposed to proper beating. An electric shock to the chest can cause momentary paralysis of the heart muscle, after which the heart will sometimes start organized beating again. A defibrillator is a device that applies a strong electric shock to the chest over a time of a few milliseconds. The device contains a capacitor of a few microfarads, charged to several thousand volts. Electrodes called paddles, about 8 cm across and coated with conducting paste, are held against the chest on both sides of the heart. Their handles are insulated to prevent injury to the operator, who calls Clear! and pushes a button on one paddle to discharge the capacitor through the patient's chest Assume an energy of 3.00 102 W s is to be delivered from a 30.0-F capacitor. To what potential difference must it be charged?

The electrical signals to the heart are typically coordinated to create a wave of compression that travels across the heart and pumps the blood through the heart chambers. If these signals get misaligned, the bits of the heart muscle vibrate independently and as a result do not move blood. This situation is called fibrillation and can quickly lead to death. If the situation is caught in time, passing a jolt of current through the heart can realign the electrical signals in the heart and start it beating again. The device that delivers this current is a defibrillator. The central component of a defibrillator is a big capacitor. A battery takes perhaps half a minute to charge this capacitor. A typical defibrillator capacitor might have a capacitance of 54 μF and is charged by a battery to a potential difference of 4200 V.1. What is the magnitude of charge stored on one of the capacitor plates when it is fully charged?|Q| = _____ μC 2. The energy stored in a capacitor is ½|Q||ΔV|. How…
