Question One mole of nickel (6 x 1023 atoms) has a mass of 59 grams, and its density is 8.9 grams per cubic centimeter. You have a long thin bar of nickel, 2.2 m long, with a square cross section, 0.12 cm on a side. You hang the rod vertically and attach a 149 kg mass to the bottom, and you observe that the bar becomes 1.12 cm longer. Calculate the effective stiffness of the interatomic bond, modeled as a "spring": kg 1.3165 X N/m

A block of mass m is sliding over an inclined plane and is connected by a cable to a solid of fixedmass M. In a first experiment, an oil of viscosity U1 is used, resulting in a terminal velocity V1 ofthe block. When an oil of viscosity U2 is used, the terminal velocity is V2. Note that the blockmass m, and the suspended mass M are the same in both experiments.a) Assuming a linear velocity profile in the gap between the bloc and the inclined plane, showthat the ratio of the two viscosities is inversely proportional to that of the two speeds.b) When an oil of viscosity 0.1Pa.s is used, the terminal velocity is 20cm/s. Determine the valueof the terminal velocity when a liquid with a viscosity twice that of the oil is used.
A hanging wire made of an alloy of aluminum with diameter 0.05 cm is initially 3.0 m long. When a 7 kg mass is hung from it, the wire stretches an amount 1.69 cm. A mole of aluminum has a mass of 27 grams, and its density is 2.7 g/cm3. Based on these experimental measurements, what is Young's modulus for this alloy of aluminum? Y= ____________N/m^2. As you've done before, from the mass of one mole and the density you can find the length of the interatomic bond (diameter of one atom). This is 2.55 10-10 m for aluminum. As shown in the textbook, the micro quantity ks,i (the stiffness of one interatomic bond) can be related to the macro property Y: ks,i = _______N/m
