Consider a steel guitar string of initial length l=1.00 meter and cross-sectional area a=0.500 square millimeters. the young's modulus of the steel is y=2.0×10¹¹ pascals. how far ( δl) would such a string stretch under a tension of 1500 newtons? use two significant figures in your answer. express your answer in millimeters.

Fill in the blank. the number of each type of element in the compound (other than 1) is represented by a small number to the right of the element symbol.

While standing outdoors one evening, you are exposed to the following four types of electromagnetic radiation: yellow light from a sodium street lamp, radio waves from an am radio station, radio waves from an fm radio station, and microwaves from an antenna of a communications system. rank these type of waves in terms of increasing photon energy.

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
