A toy is placed in a fish tank 3/4 of water. Attached to tire is a pulley. The weight of the tire is .36 N outside of water. Weight after tire is pulled under water is .45 N. What is the density of the toy in g/cm3?
Solutions
Expert Solution
The additional mass inside the water is due to the buoyant
force. This additional mass is can be called as buoyant mass
and it is given by,
where,
= mass of the body in air (or vacuum)
= fluid density
= object density
as it is the ratio of the same quantities(density), it is
unitless, so we will consider the density in 
this will make no difference.
the density of the water is 
this is density of the toy.

A rock sits at the bottom of a fish tank and the level of the
water in the tank is noted. The rock is then put into an old
fashioned ice cube tray (made from aluminium) and is floated on the
top of the water. The level is again noted. Which of the following
is true?
a). The water level is the same before and after.
b). The water level is higher before when rock is at the bottom
of...

A metal bar, initially at 2000K, is placed in a large tank of
water at room temperature. Tank is well isolated from the
environment. Between the moment bar was placed in the water and the
moment when bar and water reached equilibrium, did the entropy of
the metal bar increased, decreased, or remained the same?
Explain.

A
tank contains 100 gal of water. Brine enters the tank at the rate
of 3 gal/min. The mixture, thoroughly stirred, leaves the tank at
the rate of 2 gal/min. If the salt concentration in the brine at
the end of 20 minutes is to be 2 lb/gal, what should be the salt
concentration in the brine entering the tank?

A tank contains 100kg of salt and 2000L of water. Pure water
enters a tank at the rate 6L/min. The solution is mixed and drains
from the tank at the rate 3L/min. ) Find the concentration(kg/L) of
salt in the solution in the tank as time approaches infinity.
(Assume your tank is large enough to hold all the solution.)

A 4 m-wide tank with height of 1.8 m filled with water is pulled
with a cable inclined at 30o to the horizontal. The constant
acceleration value in the cable direction is 4 m/s². The water
depth is measured as 1.5 m before the motion starts. Determine
the angle between the water surface and the horizontal. Compute
the maximum and minimum pressure values on the bottom of the tank.

A water tank is spherical in shape with radius of
90 feet. Suppose the tank is filled to a depth of
140 feet with water. Some of the water will be
pumped out and, at the end, the depth of the remaining water must
be 40 feet.
i) Set up a Riemann sum that approximates the volume of the
water that is pumped out of the tank. (use horizontal slicing). You
have to draw a diagram and choose a coordinate...
