and the spring scale reading when submerged in water is 3N , the density of water is 1000 kg/m^3
a) caluculate the buoyant force in water
b) calucualte the volume of object
c) calculate the density of object
d) how would the aboslute pressure at the bottom of the water change if the object was removed? explain your answer
thanks gintable. I have a quick question. what does rho_ojb stand for?

A brick of mass 2.0 kg is "weighed under water" by hanging it from a spring scale ad suspending it in a beaker of water.
If the spring scale reads 14.0 N, what is the upward force of the water on the brick?
What is the reading on the pan scale on which the beaker sits? The weight of the water and the beaker together is 12.0 N.

A 50g thermometer is used to measure the temperature of 180 mL of water. The specific heat of the thermometer, which is mostly glass, is 750 J/kg K, and it reads 18.0 degree C while lying on the table. After being completely immersed in the water, the thermometer’s reading stabilizes at 75.1 degrees C. What was the actual water temperature before it was measured?

A 5 kg rock suspended above water weighs 49 N. When suspended beneath the surface of the water, its apparent weight is 48.0 N. The buoyant force on the rock is 1 N. The scale reading when the rock is released and rests at the bottom of the container is 58.8 N.
If the container of water on a bathroom type scale weighs 9.8 N, what is the scale reading when the rock is suspended beneath the surface of the water?

The drawing shows a spherical reservoir that contains 4.70 x 10^5 kg of water when full. (height of house b above ground = 7.40 m.) The reservoir is vented to the atmosphere at the top. For a full reservoir, find the gauge pressure that the water has at the faucet in each house. Ignore the diameter of the delivery pipes. The cylinder base that holds up the sphere of the tower is 15m tall.
