Question:
A piece of wax is attached to a newton-meter. In air, the reading on the newton-meter is 0.27 N and when submerged in water of density 1,000 kg m−3 the
reading is 0.16 N. Calculate:
a. The upthrust on the wax when in water
b. The volume of the wax
c. The reading on the newton-meter when the wax is submerged in a liquid of density 800 kg m−3.
Step by Step Answer:
a The upthrust on the wax when in water can be calculated by subtracting the reading in ...View the full answer
