Magnetic force is the key simple but no has done it magnetic force repels to create rotation if applied right the force could be harnessed to create rotation this constant frictionless rotation could be used with simple coils for electricity. This would be perpetual motion no outside energy required its like using gravity
minimal outside or no outside help would be required. Give me ideas if you think your smart?

Magnteic force is the answer for constant rotation. Rotation applied
in a large facilty using magnets materials coils could produce electricty at an alarming rate. frictionless energy would result. Magnets repel to create rotation static charge using coils wouls produce electricty lubrication could minimize friction between coils
result contant energy proudction with no extrenal power source.

Is it? Doesn't the answer come out negative? This is a problem from our calculus textbook that looks a bit fishy to me. It then asks you to do the following, assuming it is a probability density function (which I'm sure it isn't)...

A) Determine the expected value and standard deviation

b) Determine the median

c) find the probability that x is within one standard deviation of the mean.

I am building a basic drug simulation program for a project right now where you are tasked with modeling the concentration of whatever drug in the body, specifically the oral, central, and peripheral compartments. To enhance my model I am looking to add gender, age, and weight factors.


My question specifically: What are the some general effects of gender, age, and weight on the metabolization of drugs in the body?
