Textbook Question
Chapter 1, Problem 1.2P
Folklore has it that Sir Isaac Newton formulated the law of gravitation supposedly after being hit on the head by a falling apple. The weight of an apple depends strongly on its variety, but a typical weight is 1 newton! Calculate the total mass of 100 apples in kilograms. Then convert the total weight to pounds and the total mass to slugs.

A block of metal measures 12 cm by 10 cm by 10 cm.
When the block is hung from a spring scale, as shown in
Figure 3a, the scale reads 30 kg. This is the "true mass"
of the block. Suppose we attempt to measure the block's
mass under water. The same mass, while hanging from
the same scale, is completely submerged in water, as
shown in Figure 3b. What is the reading (in kilograms)
on the spring scale? Show and explain your work.
