What is the density of an object that has a mass of 184g and a volume of 50cm CUBED?
The density of the object is calculated by dividing the mass (184g) by the volume (50 cm^3). Therefore, the density of the object is 3.68 g/cm^3.
How does liquid pressure different with density of liquid?
Imagine three glass tubes with equal cross-section of 1 square cm and of length 100 cm each. Fill the first tube with water to the 75cm mark, the second to the 50cm mark and the third to the 25cm mark. The density of water would be one of the following 1) Mass of the 75cm column with a cross section of 1 sq cm divided by 75 cubic cm 2) Mass of the 50cm column with a cross section of 1 sq cm divided by 50 cubic cm 3) Mass of the 25cm column with a cross section of 1 sq cm divided by 25 cubic cm and in each case should give you an answer close to 1 gm per cubic cm. Thus the density stays the same no matter how high the water is in each tube. On the other hand the pressure at the bottom of each tube is different and is the force exerted per unit area by the column of water in each tube which are again different. We have conveniently selected tubes with 1 sq cm (unit area in CGS system) cross sectional areas. So the weight of the column in each tube would be the pressure. Hence the pressure in the first tube would be 1) Weight of the 75cm water column = 75 x 1 x g = 75g dynes 2) Weight of the 50cm water column = 50 x 1 x g = 50g dynes 3) Weight of the 25cm water column = 25 x 1 x g = 25g dynes Thus density remains the same for a given temperature and pressure but the pressure depends on the weight the column of liquid per unit area.
A convex lens forms a real and inverted image of a needle at a distance of 50cm from the lensWhere is the needle placed in front of the convex lens so that the image is of the same size as the object?
A convex lens forms a real and inverted image of equal size only when it is kept at the center of curvature of the lens. The image is also formed at the center of curvature at the other side. Hence, the distance of object = distance of image = 50 cm. Now, focal length = � � radius of curvature = � � 50 cm = 25 cm Hope it is clear!
What is the weight of cubical block of ice 50 cm in length if 1 m3 of ice weighs 900 kg?
The volume of the cubical block of ice is 50 cm x 50 cm x 50 cm = 125,000 cm³. Converting this to cubic meters gives 0.125 m³. Therefore, the weight of the block of ice would be 0.125 m³ x 900 kg/m³ = 112.5 kg.
How much does wood expand with changes in temperature eg a 50cm oak plank going from 20C to 30C under constant humidity?
Under constant humidity wood won't expand much from 20c to 30c. Moisture is the leading cause of expansion in wood products.For an exact answer you'll need to specify with the grain or against it.You can then use the coefficients located herehttp://www.inspect-ny.com/exterior/Coefficients_of_Expansion.htm0.0000030 (across grain)0.0000027 (parallel to grain)put them into the calculator located herehttp://www.ajdesigner.com/phpthermalexpansion/thermal_expansion_equation_linear_length_change.phpWhich give the following answer0.015 millimeters across grain0.0243 millimeters Parallel to grain

What is the volume of an object that measures 30cm x10cm x 50cm?
15,000 cm3
How do you f ind volume of an object using water displacement method?
Fill a market beaker to a specific measured volume. (Eg. 50cm cubed, make sure you have not filled the beaker with water). Now place the object in the beaker with water. The water level should rise (Eg. from 50cm cubed to 60cm cubed). The difference in the original volume and the final volume is the volume of the object. That is the water displacement method.
A rectangular tank measures 150cm x 100cm x 50cm it is filled with water to a height of 30cm an object is placed in the tank the water is now at the height of 36.2cm what is the volume of the object?
If the object hsa sunk the volume is equal to the volume of water displaced If the tank is 50 cm high, the volume is 150x100x (36.2-30) = 93000 cubic centimeters
If 400kg of a metal measures 20cm X 50cm X 80cm find the density of the metal?
The mass of the sample is 400 kg = 400,000 grams.The volume is (20 x 50 x 80) = 80,000 cm3The density is (mass / volume) = (400,000 / 80,000) = 5 gm/cm3
What is the volume of a cone whose slant height is 50cm and height is 40cm?
The volume of this cone is 37,699 cm3
What object is longer than 50cm but shorter than 1m?
nothing
What the mass of steel plate with a volume 500mm by 200mm by 10mm and relative density of 7.5?
You've got (50cm x 20cm x 1cm) = 1,000 cm3 there. (That's a liter !)Since its density is 7.5 times the density of water, its mass is 7.5 kg .It weighs 73.6 newtons (16lb 8.55oz).
What is 50cm added to 50cm?
50cm added to 50cm = 100
How do you measure 50cm of water?
To measure 50cm of water, you can use a ruler or a measuring tape to gauge the water level in a container. Ensure the container is transparent and has volume markings to make the measurement accurate to 50cm. Adjust the water level until it reaches the desired height.
How many liters in a tank 500mm by 500mm by 500mm?
If the tank is a cube, and each edge is 500mm long, then the volume of the tank is50cm x 50cm x 50cm = 125,000 cm3 = 125 litres.
How many 50cm are there in 3m 50cm?
350cm/50cm=7
