Question

A 4.5 kg iron block is suspended from a spring scale and is submerged in a fluid of unknown density. The spring scale reads 3.5 N. What is the density of the fluid? The desity of iron is 7. 80 × 103 kg/m3

Answer #1

2) A 6.00kg block is suspended from a spring scale and submerged
in a liquid.The spring scale reads 10.00N.
What is the density of the liquid?

A
solid block is attached to a spring scale. When the block is
suspended in air, the scale reads 20.0 N; when it is completely
immersed in water, the scale reads 16.7 N.
Part A) What is the volume of the block?
Part B) What is the density of the block?

A block has a weight of 50 N when it is measured on a spring
scale. The spring scale then measures 32 N when the block is
submerged in water that has a density of 1000 kg/m3.
What is the volume of the block in m3?

A solid block is attached to a spring scale. When the block is
suspended in air, the scale reads 22.6 NN; when it is completely
immersed in water, the scale reads 15.1 NN.
Part A
What is the volume of the block?
Express your answer using two significant figures.
Part B
What is the density of the block?
Express your answer using two significant figures.

The gravitational force exerted on a solid object is 4.20 N.
When the object is suspended from a spring scale and submerged in
water, the scale reads 3.00 N (figure). Find the density of the
object.

An iron cube of unknown mass is suspended by a string
from a scale that can measure its weight. If you were to lower the
cube into three different substance - corn syrup, vegetable oil,
and rubbing alcohol- in which would the cube have the smallest
apparent weight? density of : iron 7874 kg/m3 density of corn syrup
=1400 kg/m3 density of vegetable oil = 930 kg/m3 and density of
rubbing alcohol = 786 kg/m3

A) What is the block's volume?
B) What is the block's density?

A block of mass 604 g and side length 10.4 cm is suspended on a
spring into a fluid of density 1780 kg/m3. The block is
pulled up a distance 10 cm and it takes 3.3 s for the block to make
3 full oscillations, by which time the oscillation amplitude falls
to 6 cm.
(a) Find the drag coefficient of the fluid.
(b) Find the stiffness of the spring.
