Suppose that the supply of aged cheddar cheese is inelastic, and the supply of bread is elastic. both goods are considered to be normal goods by a majority of consumers. suppose that a large income tax increase decreases the demand for both goods by 10%. refer to scenario 5-3. the price elasticity of supply for aged cheddar cheese could be?

A0.750 kg aluminum pan is removed from the stove and plunged into a sink filled with 10.0 kg of water at 293 k. the water temperature quickly rises to 297 k. what was the initial temperature of the aluminum pan? the specific heat of aluminum is ca = 900 j/(kgk) and water is cw = 4190 j/(kgk)

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?

How do you know how many valence electrons an atom has?
