Ight, Ive got these 2 problems I cannot figure out for the life of me. Maybe you guys can be of some assistance.
#1) You are preparing some apparatus for a visit to a newly discovered planet Caasi having oceans of glycerine and a surface acceleration due to gravity of 3.20 m/s2. If your apparatus floats in the oceans on earth with 23.0% of its volume submerged, what percentage will be submerged in the glycerine oceans of Caasi?
#2) Lift on an Airplane. Air streams horizontally past a small airplane's wings such that the speed is 70.0 m/s over the top surface and 46.0 m/s past the bottom surface. If the plane has a wing area of 16.6 m2 on the top and on the bottom, what is the net vertical force that the air exerts on the airplane? The density of the air is 1.20 kg/m3.
I think for #2 Im supposed to use burnoullis equation, but there is no Y height in the question.
Thanks. This is due at 11:00 tonight by the way
