The density of an object with a mass of 16 g and volume of 8 cm^3 would be 2 g/cm^3.
To find the density, first calculate the volume of the block by multiplying the three dimensions (12cm x 8cm x 9cm = 864cm³). Then, divide the mass (75g) by the volume to find the density. So, the density of the wood block is 75g / 864cm³ ≈ 0.09 g/cm³.
The magnifying power of a lens is given by 1 + (D/F), where D is the least distance of distinct vision (typically 25 cm) and F is the focal length of the lens. Given a focal length of 8 cm, the magnifying power would be 1 + (25/8) = 4.125.
The pressure exerted by a column of mercury is given by the equation P = hρg, where h is the height of the column, ρ is the density of mercury, and g is the acceleration due to gravity. Since the pressure inside and outside the tube remains the same, the length of the air column will be the same when the tube is fixed vertically. Therefore, the length of the air column will be 10 cm.
This is a question on plane geometry and involves Pythagorastheorem. The ant finishes at a point which we will call point C. You have created a right angle triangle. As we know the length of two of the sides we can calculate the third with the theorem. The theorem is "the square on the hypotenuse of a right angled triangle is equal to the sum of the square on the other two sides". That may sound complex but it is not, work it out like this. One side of the triangle is 6cm so you square this number (multiply it by itself 6 x 6) = 36. The other side is 8cm so you do the same (8 x 8) = 64. Then add the two together. 36 + 64 = 100. You then need to find the square root of this number. In this case it is 10. So the distance traveled is 6 + 8 = 14cm and the displacement from the original point is 10cm
You don't leave it very clear what the question is. But problems that involve mass and volume MIGHT be related to density. To calculate the density, divide themass by the volume.
Density = mass/volume = 4g/8cm3 = 0.5g/cm3
density = mass/volume = 50g/8cm^3 = 6.25 g/cm^3
The volume is 1608.5cm3
To find the density of the cube material, divide the mass of the cube by its volume. You would first need to know the volume of the cube to calculate its density accurately. If the volume of the cube is 8cm³, then the density would be 96g/8cm³ = 12g/cm³.
128pi.
Volume = 8cm * 8cm *8 cm = 512 cm3
density = mass/volume = 4g/8cm³ = 0.5 g/cm³
The volume is 512 cm3
The substance's density is 0.11 g/cm3
The density of any substance is measured as its mass per some unit of volume. Normal units are kilograms per cubic metre, grams per cetimetre or grams per millilitre. 8cm is a measure of length: it cannot be a measure of density.The density of any substance is measured as its mass per some unit of volume.
