Are you talking about the displacment needed to lift 3000 pounds in water? The total displacment would need to equal the weight of the object AND the contianment vessel AND the entrapped air. Water weighs about 8 (fuel is 6) pounds per gallon. So you'd have to divide the total weight of all objects by 8 pounds to find the displacment. Recognize that you can also count the displacment of the object being lifted as part of the total displacment, so if the 3000 pound object displaces 100 gallons of water, that reduces the total additional displacent by 100 gallons.
direction displacement and units
In the US, $1.56.
Work = Force * Displacement. Therefore Force = Work / Displacement = 160 J / 8 m = 20 N (Note that the force and the displacement have to be in the same direction, or else the components of either of them will have to be calculated in the direction of the other)
how much postage needed to send a manilla envelope that is 13.2 ounces?
The formula will be known once information is provided on what formula is needed. Without information on what exact information is needed a person will not be able to know the correct answer.
A formula is a statement. It's not a problem or an exercise to which a solution is needed.
the empirical formula and the molar mass
The required velocity is the given displacement/the given time intervalin the direction from the starting point to the end point.
The displacements of the particle at different times. Velocity is the rate of change of displacement.
The volume of displaced water is equal to needed volume of the sample.
Iron is an example of an element needed by all organisms.
Because the centrifugal pump cannot pump air due to its loose tolerances, the positive displacement pump is needed to create the vacuum.
The force. Work=force x displacement Displacement=100m Work=? <----------------- if it's work your trying to find you need to force=? Know force and displacement. You know the Displacment, so force is missing.
A little more information is needed. Rhenium is a transition metal, and as such, can have multiple valence states. If an ionic charge is known, for example, +2, then it can be assumed that the formula for the oxide would be RhO. If percent composition by mass is known, for example, 86.5% rhenium by mass, then math can be done to determine the formula of the oxide, which in this case, would also be RhO.
In order to measure velocity you need displacement (a start location and an end location) and time.
No pulse and no breathing is when CPR is needed.
speed of light
HF This is an example of a covalent compound, so prefixes are needed to determine how many of each atom are in the compound. Since there are none, it is given that there are one of each.
Apparatus needed: Displacement can, sinker such as rock, calibrated beaker, string to attach to rock, tripod stand ( not necessary ) or level surface. Fill displacement can with water, place on tripod stand or flat surface, at the opening or ' side shoot ' of displacement can place calibrated beaker. Dip or place the rock with string attached into water of displacement can, a volume of water will flow or fall through the opening of displacement can, into calibrated beaker. This water, known as the excess water is equivalent to that of the volume of rock, simply observe the meniscus ( of calibrated beaker) and that measure will be the volume.
It is a single displacement reaction. No balancing is needed in the resulting equation. Zn + CuBr2 ----> ZnBr2 + Cu
