Aguy wire is used to support flagpoles in windy areas. these wires are anchored in the ground to provide constant stability. you need to replace the guy wire on a pole that is 20 feet tall.. the anchor point for this flagpole is 15 feet away from the base of the pole. a. how long is the wire you need to purchase to replace the old wire? b. you are also a friend determine the length of a guy wire for a 10-foot flagpole. the wire needs to be anchored 6 feet from the base of the pole. you can purchase guy wires in whole foot lengths only. using your knowledge of perfect squares, estimate the length of wire you would need to complete the project. how much wire would be left over?

Select the correct answer from each drop-down menu. compared to its surroundings, the concentration of solutes is low inside a cell. so, the cell is with respect to its surroundings. a particular solute in this cell uses energy for its transport from the cell to its surroundings. this type of transport is called

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
