the tension in the string decreases as the solid is lifted
the mass of the solid has increased
the solid apparently weighs less when completely immersed in water than when partially immersed
part of the solid still in water is exerting more force on the string
the solid is no longer in equilibrium with water
Correct answer is C

The density of a solid is defined as the
mass of the solid compared to the mass of an equal volume of water
amount of water displaced when a unit mass of thesolid is immersed in it
weight per unit volume of the solid
volume per unit mass of the solid
mass per unit volume of the solid
Correct answer is E
The density of a solid is defined as mass per unit volume of the solid
\(\frac{mv^2}{r}\)
\(\frac{mr^2}{v}\)
\(\frac{mr}{v}\)
\(\frac{mv}{r^2}\)
\(\frac{mv}{r}\)

To determine the weight of an object you could
use a beam balance
use a spring balance
find the force necessary
use none of these methods
use any of these methods
Correct answer is B
The weight of an object is found with a SPRING BALANCE.
