En la casa de RosalĂa se encuentran funcionando una bomba de agua, 2 focos ahorradores de 60 vatios o watts ( W ) y un foco incandescente de 100 W. En las terminales de la bomba de agua existe una diferencia de potencial de 120 voltios ( V ) y circula una corriente de 5 amperes ( A ). DespuĂ©s de 45 minutos, la energĂa elĂ©ctrica en casa de RosalĂa queda suspendida, debido a una descarga atmosfĂ©rica sobre el transformador que proporciona el suministro elĂ©ctrico, lo que tambiĂ©n ocasiona que Ă©ste se aĂsle de la red elĂ©ctrica y adquiera una carga elĂ©ctrica de -8000 microcoulombs ( ÎĽC ). La bomba de agua tambiĂ©n queda cargada despuĂ©s de su operaciĂłn con una intensidad de +500 ÎĽC. Considera que la bomba de agua de la casa de RosalĂa se encuentra 8 metros al norte del transformador de suministro elĂ©ctrico y 6 metros al este. 1. ÂżQuĂ© potencia elĂ©ctrica desarrolla la bomba de agua de acuerdo con las caracterĂsticas señaladas? 1.1. Anota tu resultado anterior en kilowatts ( kW ).

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.
