The concepts required to solve this problem are those related to density, as a function of mass and volume. In turn, we will use the geometric concept defined for the volume.
The relationship between volume, density and mass is given under the function
Here,
m = Mass
V = Velocity
Rearranging for the Volume,
With our information the volume is
Now the volume of sphere is expressed as
Here r is the radius of Sphere, then rearranging to find the radius we have
Therefore the radius of a sphere made of this material that has a critical mass is 9.02cm
Answer:
A) 2.5 * 10^22 molecules
B) 3.33 * 10^-9 m
C) 1134 miles/hour
D) average spacing = 2.1 m , New mass = 17 kg
Explanation:
Given data :
diameter of atom = 10^-10 m
volume of air = 1 liter
