The density of the block of wood is 0.2 g/cm^3. This is calculated by dividing the mass (3 g) by the volume (15 cm^3).
You need a unit for the mass, not just a number. In any case, the idea is to divide the mass by the volume.
The mass of an object can be calculated by multiplying its volume and density. The formula is: Mass = Volume x Density. Make sure the volume is in cubic units (such as cubic centimeters or cubic meters) and the density is in units such as grams per cubic centimeter or kilograms per cubic meter.
The density of thermocol or polystyrene is 1.64 g/cm3. it can vary due to the mass and volume of the object, the density usually ranges from 5kg/m3 to 12kg/m3.
Unknown. Everything after the collision depends on the nature of the friction between the block and the surface on which it slides. We have no way of estimating the energy dissipated as the 13.4 kg scrapes along for 15 cm before coming to rest, so we can't calculate the KE of the putty before the merger.
It is impossible to give a sensible answer to this question. The mass of 15 ml of air will be very different from the mass of 15 ml of mercury. Furthermore, the weight of either will depend on the force of gravity acting upon them. In outer space they will weigh close to nothing while on the surface of a neutron star, they will weigh a huge amount!
density = mass/volume density = 15/20 = 3/4 units/ml
Density = Mass/Volume = 30/15 = 2 grams per millilitre.
The mass is volume x density; so it is necessary to know the density of this liquid.
You need to know the volume because the density is the ratio mass/volume.
To calculate the mass of benzene, use the formula: mass = volume x density. You need to know the volume of 0.1900 L of benzene at 15°C, which can be calculated using the ideal gas law or the formula for density (density = mass/volume). Once you have the volume, multiply it by the density to find the mass.
To calculate the density of an object, you can use the formula: density = mass/volume. Given that the mass is 78 g and the volume is 15 cm³, the density would be 78 g / 15 cm³ = 5.2 g/cm³. Therefore, the density of the object is 5.2 g/cm³.
Density = mass/volume = 36/15 = 2.4 g per cm3
Density = Mass/Volume = 30/15 = 2 grams per mL.
Mass = 15 gm Volume = 2 cubic cm Density = Mass/Volume = 15/2 = 7 and 1/2 or 7.5 g per cm3
You need a unit for the mass, not just a number. In any case, the idea is to divide the mass by the volume.
The formula for density is mass/volume, hence the density is 15/5=3g/cm3
By definition: density = mass / volume Solving for volume: volume = mass / density Please note that a boy will NOT have a density of 15, at least, not if you use anything remotely related to SI units. The density of a person is close to that of water - with a density of 1, or 1000, depending on the units used.
