How does wetting the fingers change the measured resistance from one hand to another? Explain
Homework Answers
Lets consider that our body is a resistive thing, when you wet your fingers, which can be analogus to have water(another resistance) parallel to the surface of hands. We know that the equivalent of two resistors in parallel is:
Req = R1 R2/(R1 + R2)
So with the use of aboive formule effective resistance of the two elements in parallel is smaller than the smallest of two.
Hence, the resistance decreases.

How does increasing the number of resistors in a parallel branch change the total resistance of the system? - Decreases the total resistance of the circuit - Increases the total resistance of the circuit - Increases the total resistance of the circuit if the resistance of the added resistor is larger than the resistors already in the branch - Decreases the total resistance of the circuit if the resistance of the added resistor is smaller than the resistors already in...

Suppose we have two species R and S that interact with one another and that we record the change in their populations from year to year. When we begin our study, the populations, measured in thousands, are Ro and So; after k years, the populations are R and S,. If we know the populations in one year, they are determined in the following year by the expressions We will combine the populations in a vector x - and note that...

This is an interesting phenomenon, and a very difficult one to explain. Both torque and angular momentum must be treated as vectors. Torque causes angular momentum to change according to the following equation: delta L rightarrow = rightarrow delta T To use this equation the direction of a torque vector must be defined. Follow the moment arm with the fingers of your right hand. Then turn your fingers to follow the force. As you do this, your thumb will point...
