The temperature coefficient of resistivity of iron is 5.0 ´ 10-3 / °C; that of carbon is -0.50 ´ 10-3 / °C. When an iron wire and a carbon rod, each having the same 10 W resistance at 20°C, are cooled from that temperature to -80°C, the new ratio of the resistance of the carbon rod to the resistance of the iron wire at the lower temperature is

According to piaget’s stages of cognitive development, the child does not differentiate between self and other objects. the child repeats rewarding activities, discovers new ways to get what he or she wants, and may have imaginary friends. which period is described?

[05.02] what is the best explanation of the kinetic molecular theory as it relates to the energy of the molecules in the states of matter? (1 point) the molecules in a gas have greater kinetic energy than those in a liquid, which in turn have greater kinetic energy than the molecules in a solid. kinetic energy cannot be created nor destroyed, and, as a result, all states of matter have the same kinetic energy. the molecules in a gas have greater kinetic energy; therefore, they are more tightly packed than the molecules in either a liquid or a solid. the molecules in gases and liquids, in constant motion, have greater kinetic energy than those in a solid, which do not move or vibrate because their position is fixed.
