MASS, VOLUME, AND DENSITY
To determine the densities of unknown metals.
Measure the mass and volume of different metals, using a balance and the method of water displacement.
Show that the relationship between mass and volu
The uniform 20-lb ladder rests on the rough floor for which
the coefficient of static friction is s = 0.8 and against the
smooth wall at B. Determine the horizontal force P the man
must exert on the ladder in order to cause it to move.
