The gravetational force on an object is described with the formula: F = g * m
With g = 9.81 and a mass of 0.08 m3 * 7840 kg/m3 = 627.2 kg
627.2 * 9.81 = 6153 Newton.
It is the mass of the block divided by its volume.
Density of wood = mass/volume
you weigh the block on a balance get its mass if it is a regular shape block so the volume should be length * weadth * breadth (side * side * side) the density = mass / volume
Density = Mass/Volume = 13.6 g/cm3
Density = Mass/VOlume = 120g/200cm3 = 0.6 grams per cm3
5362.56 NEWTONS
9.81 m/s2 nine and eighty-one hundredths meters per second squared.
Let us formulate the formula. If suppose m is the mass of the body then mg will be the force acting on it due to gravity. If d is the density and v the volume then v d will be the mass. Hence the force due to gravity will become v d g. This force acting due to gravity is other wise known as weight of the body. Now in your problem note down the unit. It has to be in SI system. Unit for volume is m3 and that for density is kg m-3. The unit for g is m/s2 Hence as per your problem, simply multiply 0.08, 7840 and 9.8. You will get the required answer.
Density = 7,840 kg/m3 Volume = 0.008 m3 (= 8 liters). Mass = (7,840 x 0.008) = 62.72 kg Force of gravity on the block = (9.8 x 62.72) = 614.656 newtons (138.27 pounds) Bouyant force = weight of 8 liters of water = 78.4 newtons (17.64 pounds) Weight of the block in water = (614.656 - 78.4) = 536.256 newtons (120.64 pounds)
Density = Mass/Volume
It is the mass of the block divided by its volume.
4096 cm is not a volume, but a length. Once you know the volume, divide the mass by the volume to get the density.
Specific gravity and density will have the same value when the two substances under investigation have identical densities. Let's look at this. Density is an expression of the amount of mass per unit of volume that a substance exhibits. Liquid water has a maximum density at about 4 °C. And there is 1 gram in a cubic centimeter or a milliliter of water. We say water has a density of 1 gram/cubic centimeter. Other substances can have their mass discovered when a known volume is weighed, and then the density of those substances can be discovered and recorded. Specific gravity is a comparison of the density of a substance to the density of water. The specific gravity of a material will not have units associated with it. It is a purenumber. If a substance has a spee gee (lab speak for specific gravity) of 2, it will have 2 times the density of water. A cubic centimeter of this material will weigh 2grams, and will have a density of 2 grams per cubic centimeter. But, to repeat, spee gee has no units associated with it. The only time that specific gravity and density will have the same value is when the substance under inspection has the same density of water at 4 °C. That's the only time density and spee gee will have the same value. And note that we're talking value here, and without regard to units. Density has units of mass per unit of volume, and specific gravity has only a numerical value, only magnitude, and nounits associated with it.
The block's density is about 0.076 g/cm3
What is the density of a plastic block with a mass of 2.0 grams and a volume of 2.5cm3?
It depends on the volume of the block and the mass. The equation D=M/V Density=mass/volume The answered is displayed as (answer) grams/(the units in which you measured the volume) I hope this helps.
