Homework Statement Find the volume of the smallest block of ice which when floating on salt water will carry a person of mass 80 Kg Densities: Salt Water = 1025 Ice = 917 Homework Equations F_b=P_f * V_f * G The Attempt at a Solution I figured F_b would have to be equal...

Last week I went to Ripley's Believe it or not and saw this gigantic granite ball floating on water. I was wondering how much the water pressure is and what kind of calculation we need to find out the water pressure. I wanted to create a small fountain that would make the ball float. Please...

I'm sure one could find a reason to use any data type. There is a lot you can do with just intergers. I do, however, have a computational physics book and they make wide use of the type double. Could float be used as an alternative?

Im not sure if anything like this has been posted before, and I am not sure if this was the right place to post the question, ao i apologise in advance if i make anyone angry... at the beginning of the year my lecturer posted the challenge to find another compound which, like water, was lese...

First off i'd like to say hi guys (and gals) - this may be my first post, but should hopefully be the first of many:smile: Basically i have a problem regarding some physics coursework. We're actually conducting these on the 8th of November - and i have a deadline of the 20th of November...

shouldn't it float?? if one recalls the old classical physics terms namely repose angle, I've got a problem for them. as it(repose angle) is meant for is a state when a matter lying on an inclined plane with a repose angle to ground ... then there will be equilibrium between the frictional and...

Such as SkyLab? If the airplane got more horizontal velocity would things float?

i think that the reason of hot water 'float' on the cold water is not becuase of diffrent density. i make a model of a container containing a higher energy particle (hot water) and lower energy particle (cold water) using action script in flash and uploaded it in geocities...

I'm new here and not sure if this post is in the right spot (it's about Special Relativity) but here goes nothing. This problem--from the book Spacetime Physics by Taylor and Wheeler--is giving me a lot of trouble. What I think is that the scale will read zero in the air, because there...

The bottom of a steel "boat" is a 6.00 m x 9.00 m x 5.00 cm piece of steel(density of steel = 7900 kg/m^3) . The sides are made of 0.460 cm-thick steel. what minimum height must the sides have for this boat to float in perfectly calm water? in cm i have that F_B (buoyancy force) is equal...

Hi Guys! First Post! I really like the Forums, although most of the topics are way over my head. I'm hoping you can help me solve a problem. If a Truck-Trailed Gas Tanker, the kind that refuel Gas Stations, was full, would it float? Assuming there isn't any air for boyancy. My pal thinks...

I've been frustrated for a couple of days over a C programming assignment: "Convert the float value tot_bill (in dollars and cents) to integer dollars in tot_doll and integer cents in tot_cents. Make sure that the cents value is rounded, not truncated." I am assuming that we should take a...

Can anyone tell me why clouds float and don't fall down ? tx

This might sound like a stupid question, but in my physics class we have a game called "Will it float?" It's just like on the tonight show. We pick out random things to put in the water and guess if they'll float or not. My teacher decided to let us try to stump her after several weeks of her...
