What is the formula for bouyancy?
951699
I don't know if there is a physical quantity measure of bouyancy, but the idea is displace a volume of the surrounding liquid.\n\nYou can easily calculate. For example lets say you have a barrel that can hold 50 gallons and you want to know how many rocks you would have to put in it so that it will sink. You just calculate the total weight of the water that must be displaced (50 gallons - the volumn of the barrel walls is negligible). That is the same weight that the barrel + contents would have to be so that it just becomes level with the water at its lip.

You DO have to consider bouyancy.  The person who said the force of the water can be neglected is incorrect.\n   The bouancy is equal to the weight of the water displaced.  Volume of the rock is 20/4200 = .004762m^3.  Water weighs 1 gm per cubic centimeter, or 1000 kg/m^3, weight of water displaced is therefore 4.762kg.  Subtract this from 20kg to get 15.238kg.  Multiply by 9.8m/s^2 = 149.3 Newtons

volume=pir^2h=1000\nsince there are two variables we need a minimum of two equations

The mathematical formula for calculating your mortgage payment is MP = LB [ (I (1+ I)n)¸((1+I)n - 1)], in which MP is the monthly payment, LB is the loan balance, I is the monthly (annual¸12) interest rate and n is the number of periods for the amortization.

This formula might help\n\nchange in S=(m1)(c1)(ln(Tf/Tc))+(m2)(c2)(ln(Tf/Tc))\nm1 & m2=substance mass in this case oxygyn gass (O2)=15.999(2)\nc1 & c2 are spcific heats\nTc =cold temp\nTh = Hot Temp\nTf=((m1)(c1)(Tc)+(m2)(c2)(Th))/((m1)(c1)+(m2)(c2))\n\nI'm assuming m^3/kg is the pressure (Volume/Mass) ???\n\nhope this helps!!

OK, the barrel´s mass is 40Kg (notice: its mass is 40 Kg, not its weight). \n\na) So, your formula is Weight = mass(m)*gravity´s acceleration(g)= 40Kg*10m/s^2 = 400 KG*m/s^2 (=400 Newton)\n\nb) Work = force * distance\nSince work is calculated only for the vertical, and the force equals the weight, you have:\nWork = 400N*5m = 2000 Joule\n\nc) Eff = 250N*5m/2000J*100 = 0.625*100 = 62.5%\n(You got 12.5% because you forgot to multiply 250N for 5 meters. Remember that efficiency is a relation of works, and work is force * DISTANCE).\n;o)

The idea is that the increase in hydrostatic pressure of the water will cause a decrease in volume of the balloon. You are told that the temperature of the ballon is constant so that you can make the assumption PV = constant = Pa Va, where Pa Va are the pressure and volume at atmospheric conditions.\n\nThe bouyant force is simply the weight of water displaced, and therefore is it proportional to the volume of the balloon. You can assume that the water is incompressible and therefore constant density.\n\nSo, saying that the bouyant force is 1/2.4 of the surface value means that the volume has decreased to Va/2.4.\n\nPa Va = Pb Vb; Vb = Va/2.4 --> Pb = 2.4 Pa.\nRemember that this means absolute pressure.\nThe absolute hydrostatic pressure in the water is:\nPw = Pa + (rho) g h\nwhere h is the depth below the surface.\nSo: 2.4 Pa = Pa + (rho) g h\nh = (1.4 Pa)/((rho) g)\nPa = 101 000 N/m^2\nrho = 1000 kg/m^3\ng = 9.8 m/s^2\nh = 14.4 m
