Juanita is designing a flagpole to be installed in front of her school. the school has asked her to design the flagpole so that the average parent dropping off students in the morning could see the top of the flagpole when looking out of the passenger side window of their cars. if the flagpole it to be installed 75 feet from the student drop off and the average car allows for a viewing angle of 18° with an eye level of 4 feet, what is the maximum height that the flagpole could be to the nearest foot?

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

Holes drilled several kilometers into earth’s crust provide direct evidence about earth’s interior in the form of

Abus travels 280km south along a straight path with an average velocity of 88km/h to the south. the bus stops for 24 min, then it travels 210 km south with an average velocity of 75 km/h to the south. how long does the total trip last?
