Homework Statement
You, Archimedes, suspect that the king’s crown is not solid gold but is instead gold-plated lead. To test your theory, you weigh the crown, and find it to weigh 60.0 N, and to have an apparent weight of 55.3 N when it is completely submerged in water. Take the density of...
Homework Statement
A flexible tube can be used as a simple siphon to transfer fluid from one container to a lower container. The fluid has a density of 800. kg/m3. See the dimensions given in the figure, and take atmospheric pressure to be 101.3 kPa.
There are three points given:
Pt X is...
Ok, I plugged the numbers into the Pressure=Force/Area [450/(.8m^2)(Pi)] for the barrel and got the necessary pressure to be 223.81 pa.
Then to find what force would be required in the tube to cause this, I used the same P=F/A formula, to solve for F [223.81=F/((.008m)^2 x Pi), and got it to be...
I got the W(app) to be 58.8N, which makes means that the V(water) displaced is 7.2kg [m(wood)-58.8N=(90%)(V(wood)) x (p(water)] (This is how I tried to go about it using the free body diagram). From this, I determined that the W(wood)=70.56, meaning M(wood)=11.76N [70.6N-58.8N]. Using this to...
Homework Statement
As shown in the figure below, a wooden cube measuring 20.0 cm on each side floats in water with 90.0% of its volume submerged. Suspended by a string below the wooden cube is a metal cube. The metal cube measures 10.0 cm on each side and has a specific gravity of 6.00.

Homework Statement
A barrel with diameter 80cm is completely full of water and sealed except for a piece of tube extending vertically through the lid with a diameter of 0.8cm. It's asking what height would you have to fill the small tube with in order to make the lid of the barrel pop off. The...
