common iron nuclei have a mass number 56. find the radius , approximate mass, and approximate density .

with explain all steps and law's

Answer #1

An approximate experiment expression for the radius (R) of a
nucleus is R = Ro A^1/3, where Ro = 1.2 x 10^-15 m and A is the
mass number of the nucleus. (a) Find the nuclear radii of atoms of
the noble gases: He, Ne, Ar, Kr, Xe, and Rn. (b) Determine the
density of the nuclei associated with each of these species and
compare them. Does your answer surprise you?

An iron ball or radius r is suspended by a thread of negligible
mass from an upright cylinder that floats partially submerged in
water. The cylinder has a height of 6.9 cm, a face area of 12.1
cm^2 on the top and bottom and a density of .30 g/cm^3, and 2.5 cm
of its height is above the water surface. Use g = 9.8 m/s^2
a) calculate the buoyant force of the cylinder if the density of
the water is...

Consider the 6530Zn nucleus. Find
approximate values for the following.
(a) radius
fm
(b) volume
m3
(c) density
kg/m3

1. Determine the approximate radius of the nucleus of a cobalt
atom. Cobalt has 27 protons and 32 neutrons.
2. If the atomic mass of cobolt is 58.93u determine the density
of the cobalt nucleus in kg/m^3
3. Compare this to the density of cobalt metal (use google). How
does the density of cobalt metal compare to the density of just its
nucleus? If they do not match please explain why they do not
match.

A right circular cylinder is measured to have a mass of 1178.0
+/- 0.1 g, a diameter of 2.50 +/- 0.01 cm and a height of 30.48 +/-
0.01 cm.
a. Look up the volume equation for a right circular cylinder.
Remember that a radius is 1/2 the diameter.
b. The density is mass divided by volume. Find the density using
significant figures rules.
c. Find the density with error bars using the max/min
method.
d. Using a table of...

Find the moment of inertia of a uniform hollow sphere of mass M,
inner radius r, and outer radius R > r, about an axis through
the center of mass. Consider your answer for the cases r → 0 and r
→ R. Does the result reduce correctly? Explain.

Neutron stars consist only of neutrons and have unbelievably
high densities. A typical mass and radius for a neutron star might
be 8.2 x 1028 kg and 1.7 x 103 m. (a) Find the density of such a
star. (b) If a dime (V = 2.0 x 10-7 m3) were made from this
material, how much would it weight (in pounds)?

Four solid plastic cylinders all have radius 2.51 cm and length

_______________ C
Cylinder (b) carries charge with uniform density 13.7
nC/m2 on its curved lateral surface only.
_______________ C
Cylinder (c) carries charge with uniform density 525
nC/m3 throughout the plastic.
_______________ C
Cylinder (d) carries charge with uniform linear...

Four solid plastic cylinders all have radius 2.73 cm and length
5.46 cm. Find the charge of each cylinder given the following
additional information about each one. Cylinder
(a) carries charge with uniform density 14.1 nC/m2 everywhere on
its surface. Incorrect: Your answer is incorrect. Your response
differs from the correct answer by more than 10%. Double check your
calculations. ______C
Cylinder(b) carries charge with uniform density 14.1 nC/m2 on
its curved lateral surface only. ______C
Cylinder (c) carries charge...

Let X have density fX(x) = C/ sqrt(x), 0 < x <
1
(a) Find the cumulative distribution FY (y) and
probability density function fY (y) of Y = X(1 − X).
(b) Find probability density function fZ(z) of Z =
