The average resistivity of the human body (apart from surface resistance of the skin) is about 5.0 Ω⋅mΩ⋅m. The conducting path between the right and left hands can be approximated as a cylinder 1.6 mm long and 0.10 mm in diameter. The skin resistance can be made negligible by soaking the hands in salt water. If skin resistance is negligible, what potential difference between the hands is needed for a lethal shock current of 100 mAmA? (Your result shows that even small potential differences can produce dangerous currents when the skin is damp.)

At the surface, the average total lung capacity of human lungs is about 6 liters of air (~0.21 ft3). Free divers typically fill their lungs with air and hold their breath while they dive. Assuming that Boyle’s Law accurately reflects changes in the air volume in a free divers’ lungs, calculate the change in volume that would occur in a free diver’s lungs at the following depths below the surface of the ocean: 10m, 20m, 35m, 45m. Finally, the world...

We want to build a circut that measure the resistance of the human body and convert it to voltage and the circut should have a led that work when the resistance of the body is low. And also we want to use a 741 op-amp And the measured resistance of the body can be represented by a variable resister(the concept of our circuit is to measure galvanic skin response )

Thick skin can be found in only two locations on the human body. Name the two locations Then, identify some anatomical differences between thick and thin skin. Explain why these differences are so important.

If the average survival of a red cell in the human body is 120 days with...

If the average survival of a red cell in the human body is 120 days with a standard deviation of 8 days, what is the probability for each of the following events? Assume a normal distribution, a. A red cell surviving more than 134 days? b. A red cell that survives less than 110 days? c. A red cell surviving between 108 and 122 days?

The human body contains about 10^(14) cells, and the diameter of a typical cell is about 10 micrometers. Like all ordinary matter, cells are made of atoms; a typical atomic diameter is 0.1 nanometers. I have all of the correct answers, but I do not know how to get to these answers or solve them on my own. I would like to get explanations (why?) and see how it should be done (math being done). a) How does the number...

The resistance of the body varies from approximately 500 kΩ (when it is very dry) to about 1.00kΩ (when it is wet). The maximum safe current is about 5.00 mA. At 10.0mA or above, muscle contractions can occur that may be fatal.a)What is the largest potential difference that a person can safely touch if his body is wet?b)Is this result within the range of common household voltages?

Are there any parts of the human body that get oxygen directly from the air and not from the blood?
