12-29 A soda glass specific gravity
bottle having a volume 5.250 x 10-
m' is filled with glycerin at 0°C. The
bottle and its content are heated to
50°C. Calculate the mass of glycerin
that will spill out of the specific
gravity bottle. Coefficient of linear
expansion of soda glass 8.5 x 10°K,
coefficient of volume expansion of
glycerin is 5.2*10*K' and specific
gravity of glycerin at 0°C is 1.26.
[Answer = 15.94 mg]

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

What statements accurately describe atoms

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
