How many lead ball each of radius 1 cm can make a sphere of radius 8 cm?
The volume of a sphere is 4/3*pi*r3 So Vol8/Vol1 = 83/13 = 83 = 512
Why is the world a sphere?
Gravity pulls with equal strength in all directions; therefore any variations from a spherical shape will lead to gravitational forces that bring the shape back into that of a sphere.
The EPA limit for lead in the soil of play areas is 400 ppm This is the same as?
400 mg lead in each kilogram of soil.
A piece of lead pipe of inner diameter 5.72 cm outer diameter 6.67 cm length 40.64 cm has been melted in an open conical pot of radius 25.4 cm altitude 38.1 cm. Find the depth of the molten metal?
Is this taking into consideration the dross content as the metal melts it oxides? and how much does the lead pipe weigh per foot?
How do you get the lead out of a Staedtler compass?
The lead is held in place by tightening a knurled bolt. Open the bolt and remove the lead.
How many balls of radius 4 cm can be made from a solid sphere of lead of radius 8 cm?
16
How many balls each of radius 1 cm can be made from a solid sphere of lead of radius 8 cm?
It is: (4//3*pi*83) divided by (4/3*pi*13) = 512
How many lead ball each of radius 1 cm can make a sphere of radius 8 cm?
The volume of a sphere is 4/3*pi*r3 So Vol8/Vol1 = 83/13 = 83 = 512
How do you calculate the density of lead in a sphere?
The density of lead is well known; you can look it up in any reference book on chemistry, or on the Internet. It is 11.34 grams per cubic centimeter, according to Wikipedia. But if you have a sphere that is only part lead, you can get the density of the sphere by weighing it, and dividing the weight by its volume. The volume of a sphere is 4/3 x pi x r ^ 3, where r is the radius of the sphere.
Which element has a larger atomic radius silicon or lead?
Atomic radius of Si is 111pm.Atomic radius of Pb is 175pm.Therefore lead has a larger atomic radius than silicon.
What were musket balls made of?
They were made of lead
A uniform lead sphere and a uniform aluminium sphere have the same mass what is the ratio of the radius of aluminium sphere to the radius of the lead sphere?
d=m/v v= (4/3)(pi)(r^3) set up equation for aluminum and lead 11.3*10^3=m/( (4/3)(pi)(ri^3)) 2.7*10^3=m/( (4/3)(pi)(ra^3)) solve for m. then set two equations equal to each other, since they have the same masses. finally, solve your new equations for ra/ri 11.3*10^3( (4/3)(pi)(ri^3)) =m 2.7*10^3( (4/3)(pi)(ra^3)) =m 11.3*10^3( (4/3)(pi)(ri^3)) = 2.7*10^3( (4/3)(pi)(ra^3)) 11.3*10^3/2.7*10^3 = (ra^3)/(ri^3) (11.3*10^3/2.7*10^3)^(1/3)=ra/ri
Can 2 balls with the same diameter have the same mass?
2 balls of the same diameter can have the same mass. Equally, they can have a different mass. (i.e Having the same diameter does not automatically mean that they are the same mass).However, they will have the same volume. In maths, volume of a sphere (ball) =4/3*(pi)*radius^3. Hence volume is directly proportional to diameter (radius is half the diameter).Mass is a measure of "how dense something is" (e.g lead, wood and concrete are all dense, whereas meringue and mousse are not) Mass has nothing to do with the size of the ball, only what substance the ball is made up of. Whereas volume is easiest of think of as "how much water can I fit in this" (volume is directly related to the size of the container).Hope that helps, rather than confuses.
