1)A rock is suspended from a string in air. The tension in the
string is 2.94N. The rock then is
submerged in a liquid, and the tension in the string drops to 2.06
N. If the density of the rock is
2.55 g/cm^3 what is the density of the liquid?
2)When exposed to sunlight, a hole in a sheet of copper expands
in diameter by
0.153% compared to its diameter at 68 F. What is the temperature of
the copper
sheet in the sun? Coefficient of linear expansion for copper is
1.66 x 10-5 (0 C)^-1
