A metal sphere with radius ra is supported on an insulating stand at the center of a hollow, metal, spherical shell with radius rb. There is charge +qon the inner sphere and charge −q on the outer spherical shell. Take V to be zero when r is infinite. Part G. Suppose the charge on the outer sphere is not −q but a negative charge of different magnitude, say −Q. Find the potential of the inner sphere with respect to the outer. Express your answer in terms of the given quantities and appropriate constants. V_{ab} = ?Part H. Suppose the charge on the outer sphere is not −q but a negative charge of different magnitude, say −Q. Find the electric field at any point between the spheres (rarb. Express your answer in terms of the given quantities and appropriate constants. E = ?

In a good thermo flask the main cause of heat loss is

Glass has a hardness that is in the middle of the hardness scale. what is the hardness of glass?

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.
