Answer: z = 2
solution:
formula of z value is
z = x - μ / σ
so z = 40-30 / 5 = 10/5 = 2#
So the height will equal 95.50 inches.
So if you double the height the volume is 1800cm3 and that is double the original volume
And if you double the height the volume is 3600cm3 and that is the triple the original volume
Cobalt has an atomic number (Z) of 27, which means the nuclei of all its isotopes have 27 protons. Cobalt 60 has an atomic mass of 60, so it has 60-27 = 33 neutrons.
The mass of 27 isolated protons plus the mass of 33 isolated neutrons would be:
27*(1.007825 u) + 33*(1.008665 u) = 60.497220 u
The actual mass of the nucleus of 60-Co is 59.933820 u.
Mass defect: 60.497220 u - 59.933820 u = 0.563400 u
The mass defect is equal to the binding energy of a nucleus.
using the fact that 1 u = 931.5 MeV/c^2
(0.563400 u)*(931.5 MeV/u) = 524.807 MeV
Answer:
the thrid one
Step-by-step explanation:
Answer:
Step-by-step explanation:
According to congruent chords and arcs theorem, if then .
This means that
Thus:
(full circle = 360°)
Plug in the values into the equation
Add like terms
Subtract 36 on both sides
Divide both sides by 12
