Coloque verdadero o falso El Joule (J) es la unidad de medida del trabajo Para que el trabajo se produzca debe haber una fuerza aplicada, un desplazamiento producto de su accionar, y la fuerza debe tener una componente a lo largo de dicho desplazamiento. El trabajo se simboliza con la letra T Toda fuerza perpendicular al movimiento realiza trabajo El trabajo neto o total es la suma de los trabajos realizados por c/u de las fuerzas de un sistema sobre un cuerpo El trabajo mecánico es una magnitud escalar y su valor puede ser cero, positivo o negativo La fuerza de rozamiento hace trabajo negativo porque se opone al movimiento del cuerpo

i think the miocene epoch spans the time from 23 million to 12 million years ago.

what's the question ?

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

"it built up in the atmosphere"

i think thats it, idk, i tried looking for this exact q& a for grad. and idk if i got this question right or sorry if im wrong
