The resistance of the skin on a person's finger is typically about 15,000 Ω. How much voltage would be needed to cause a current of 0.001 A to flow into the finger? (This is about enough current to just be felt by most people.)

The relatively high resistivity of dry skin, about 1 × 106 O·m, can safely limit the flow of current into deeper tissues of the body. Suppose an electrical worker places his palm on an instrument whose metal case is accidentally connected to a high voltage. The skin of the palm is about 1.5 mm thick. Estimate the area of skin on the worker’s palm that would contact a flat panel, then calculate the approximate resistance of the skin of the...

Electric current passing through a human body can be dangerous, even fatal, depending on the amount of current, the duration of the current, and the region of the body through which the current passes. However, currents less than about 0.5 mA are typically imperceptible. A current caused by a low potential difference typically travels through the outer layer of the skin. The resistance of the skin therefore determines how much current flows for a given potential difference. The resistance can...

Typically, 20.0 % of this blood, and other uses of mechanical energy, while the rest goes to heat. Most people get rid of all of this excess heat by transferring it (by conduction and the flow of blood) to the surface of the body, where it is...

1. An average nerve axon is about 5x10-6m in radius, and the axoplasm that composes the interior of the axon has a resistivity of about 2 Ω ⋅m. What is the resistance of just 2-cm length of this axon? Provide your answer in mega-ohms (1 mega-ohm = 106 ohms or "millions of ohms"). (Note, this value is so large -- it corresponds to the resistance of tens of thousands of miles of the thinnest copper wire normally manufactured(!) -- that it...

Take a look at what and how much the people of our country know about statistics. Are we adequately educated in the ins and outs of statistics? Do we know enough about statistics to make informed decisions? What is the state of statistics education in America? Is education on statistics adequate and, if not, how can it be improved?

1. I hear people talking about how a person's personality can change throughout their life depending on the people they associate themselves with and can be changed if they change their lifestyle or the people they surround themselves with. But according to Freud's development of personality theory, person's personality is established at Stage 5, seeming almost as if it is genetic. I have no actual opinion of whether it is genetics or social, but I do believe it is a...
