What problem(s) was hempel hoping to avoid by developing this model? explain the deductive-nomological model ('covering law model') in your own words. what are the strengths and weaknesses of hempel's model? do you find this be a strong model for scientific explanation? why or why not (or perhaps you find both strengths and weaknesses)?

Acar moves at 12m/s and coasts up a hill with a uniform acceleration of -1.6m/s2. how far has it traveled after 6.0s?

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?

The electronic structure or chlorine is 2.8.7 what is the electronic structure of fluorine?
