Transcribed Image Text:A cube-shaped block A of side length a is hanging from a spring balance D,
which reads, in units of mass, Mp. The block is submerged in liquid C, which
has a total mass of me and is inside beaker B with mass mp. The beaker
rests on an electronic scale E with a readout of ME.
a) Draw force diagrams for block A and beaker B.
b) What is the mass mд of block A in terms of the given variables?
c) What is the density pc of liquid C?
d) The block is now pulled out of the liquid. What are the new readings M
and Mg on the balance and scale?
e) Compare the readouts of the balance and scale before and after the block
is pulled from the liquid for the values a = 0.1 m, mg = 1 kg, mc = 5 kg,
MD = 3.5 kg, and MĘ = 7.5 kg.
