well for the first question, I forgot to convert to cm. However, I did use F=PxA with the pascals that they gave me, plus the area of the top of the block. Am I supposed to add the Pinitial also?
Well that makes sense. See our teacher never explains to us these things.
However, now when I use the pressure that I got, 12644352 and plug it into P=F/A for part II, I get the wrong Newtons.
No, thank you! Although I'm not sure why you would have to add the pascals... I thought the equation P=pgh already encompassed the atmospheric pressure ><
1. A 11.4kg block of metal is suspended from a scale and immersed in water. The timensions of the block are 12.7cm x 9.9cm x 9.2cm. The 12.7cm dimension is vertical, and the top of the block is 4.94cm below the surface of the water. The acceleration due to gravity is 9.8m/s^2.
What is...
[SOLVED] Density/Sea Water Problem
Assume the density of sea water is 1024 kg/m^3 and take the atmospheric pressure equal to 101000Pa. The acceration due to gravity is 9.8m/s^2. Calculate the pressure at an ocean depth of 1260m. Answer in Pa.
Calculate the total force exerted on the...
Hi! I've been working on this problem for a while, subtracting this and that.. but i can't get the answer which is 557m/s. Help would be greatly appreciated! Thanks in advance ><
