Thanks, I used the P=density x height x gravity and got the same answer. Thank you very much!

Yes! Thank you! It sounds so trivial now, thanks again.

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. a)...

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...
