Definition of volume of a regular solid?
There isn't a single formula for solids of different shapes. For a right solid with a rectangular base, volume is base area x height. Similarly for cylinder with a circular base, volume = base area x height (base area in this case is Pi x radius2). For a sphere, volume = 4/3 x Pi x radius3.
A solid in which electrons are able to move about easily from one atom to another is called a?
A solid in which electrons are able to move easily from one atom to another is called a conductor. Conductors allow electric current to flow freely through them due to the mobility of electrons. Metals like copper and aluminum are examples of good conductors.
What is a trait of a substance by itself?
Density is a trait of a substance by itself. It is a physical property that describes the compactness of a substance and is independent of the amount of the substance present.
Whats the difference between morula and blastula?
An egg undergoes cell division and starts to become an embryo after fertilization. One cell divides into two, these then cleave into four, those four cells become eight, and so on. When there are a hundred or more cells, the embryo becomes a solid mass of cells called a morula. In most species the mass next transforms into a hollow sphere called a blastula.
What is the density of silver at room temperature?
The density of silver at room temperature is 10,49 g/cm3. The relative density is the same. Pure silver is very hard to find on Earth. Generally, silver found has a density which ranges from 10 to 12 gram per cubic centimeter based on the amount of impurity.
How do you find the radius of a sphere based on the weight in pounds?
You need to know if the sphere is solid or hollow. You also need the "density" in terms of pounds weight per unit volume. Then Volume = Mass/Density And Radius = cuberoot[3*Vol/(4*pi)]
What is the moment of inertia of a solid sphere?
The moment of inertia of a solid sphere is given by the formula (2/5) m r2, where m is the mass of the sphere and r is the radius of the sphere.
What is the formula for calculating the moment of inertia of a solid sphere?
The formula for calculating the moment of inertia of a solid sphere is (2/5) m r2, where m is the mass of the sphere and r is the radius of the sphere.
How many balls of radius 4 cm can be made from a solid sphere of lead of radius 8 cm?
16
How do you derive the moment of inertia of solid sphere?
mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)
What part of the earth is a solid metallic sphere about 1216 kilometers in radius?
The inner core of the Earth is a solid metallic sphere made primarily of iron and nickel with a radius of about 1216 kilometers. It is surrounded by the liquid outer core and the solid mantle.
What is a steradian?
A steradian is the solid angle subtended at the centre of a sphere by radius r by a portion of the surface of the sphere which has area r2.
What part of earth is a solid metallic sphere about 1216 kilometers in radius?
inner core
A solid rectangular block of metal 49cm by 44cm by 18cm is melted and formed into a solid sphere find the radius ofthe sphere?
To find the radius of the sphere, we need to know that the volume of the rectangular block is equal to the volume of the sphere. The volume of the rectangular block is 49 x 44 x 18 = 38,808 cm³. Equating this to the volume of a sphere (4/3πr³), we can solve for the radius which comes out to be approximately 22.18 cm.
What is the radius of a solid aluminum sphere that has a mass of 87g in inches?
Mass = 87 grams and density of aluminium = 2.7g/cm3 So volume of spere = Mass/Density = 87/2.7 = 32.22... cm3 Then V = 4/3*pi*r3 = 32.22.. cm3 r3 = 32.22...*3/(4*pi) = 7.6925 so that r = 1.97 cm = 0.78 inches.
How do you determine density of sphere with Vernier caliper?
Measure the diameter and from that calculate the volume, then determine the mass of the sphere on a weighing device. Then it's just density = mass/volume ========================== It again depends on the sphere whether its hollow or its a solid sphere
Why Does an aluminum can float on water but an aluminum pole does not?
Because the overall density of a can is less than the density of water, a solid aluminium pole has a density greater than water
