The element lead, M = 207.2, has a density of 11.35 g/cm3. (a) Find the number of atoms per cubic centimeter. If the total gamma ray cross-section at 3 MeV is 14.6 barns, what are (b) the linear attenuation coefficient and (c) the half-thickness

yo yo yo its papaguy in the house lol

okay, ima .

um it shows links to uh so kinda microsoft website is that were ima go or no? ?

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
