In chemistry, reduction occurs when a substance
A) accepts electrons B) loses electrons C) rearranges its electrons internally D) breaks into its constituent atoms
A coaxial cable consists of a long, straight filament surrounded by a long, coaxial, cylindrical conducting shell. Assume charge Q is on the filament, zero net charge is on the shell, and the electric field is E1î at a particular point P midway between the filament and the inner surface of the shell. Next, you place the cable into a uniform external field –Eî. What is the x component of the
electric field at P then? 1. 0 2. between 0 and E1 3. E1 4. between 0 and -E1 5. - E1
Current understanding holds that a galaxy's type (spiral, elliptical, or irregular)
A) is always determined by the angular momentum of the protogalactic cloud that formed it. B) may either be the result of conditions in the protogalactic cloud that formed it or the result of later interactions with other galaxies. C) is determined by whether the galaxy is located in a cluster where collisions are likely or outside a cluster where collisions are less likely. D) may either be a result of the mass of the protogalactic cloud that formed it or the result of the heavy element abundance in that cloud.
