An electric heater draws a steady 16.0 a current in a circuit with a 120 v power supply. it operates 4.0 h per day for a month (30 days). the electric company charges 10.0 cents per kwh. (i) calculate the power consumed by the heater in watts. (ii) calculate the energy in kwh consumed by the heater in one month. (iii) calculate the total dollar amount charged monthly by the electric company cost

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called

Why does karst topography exist in some geographic location? a. few climates have enough oxygen b. most regions have rock layers other than limestone c. in most regions, the soil is too thin d. the water is too acidic enough in most places
