From the information in this chapter on the mass of the proton, the mass of the electron, and the sizes of the nucleus and the atom, calculate the densities of a hydrogen nucleus and a hydrogen atom. (Radius of hydrogen atom is 1 ✕ 10^-8 cm.)
density of hydrogen nucleus

______g/cm3

ddensity of hydrogen atom

___________g/cm3

Expert Solution

A hydrogen nucleus is a proton and the mass of a proton is 1.67*10^-24g

Radius of hydrogen atom is 1 ✕ 10^-8 cm

volume = 4/3r^3

= 4/3*3.14*(10^-8)^3 = 4.186*10^-24cm^3

density of nucleus = mass/volume

= 1.67*10^-24g/ 4.186*10^-24cm^3 = 0.398g/cm^3

A hydrogen nucleus is a proton and the mass of a proton is = 1.67*10^-24g + electrons = 1.67*10^-24g

Radius of hydrogen atom is 1 ✕ 10^-8 cm

volume = 4/3r^3

= 4/3*3.14*(10^-8)^3 = 4.186*10^-24cm^3

density of hydrogen = mass/volume

= 1.67*10^-24g/ 4.186*10^-24cm^3 = 0.398g/cm^3

A proton and a singly charged ion of mass 91 atomic mass units (amu) are accelerated through the same potential difference and enter a region of uniform magnetic field moving perpendicular to the magnetic field. What is the ratio of their kinetic energies? If the radius of the proton's circular path in the magnetic field is 16.8 cm , what is the radius of the path of the singly charged ion of 91 amu? By what factor must the magnetic field be...

37.52•• Quarks and gluons are fundamental particles that will be discussed in Chapter 44. A proton, which is a bound state of two up quarks and a down quark, has a rest mass of m_p=1.67×10^−27 kg. This is significantly greater than the sum of the rest mass of the up quarks, which is m_u=4.12×10^−30 kg each, and the rest mass of the down quark, which is m_d=8.59×10^−30 kg. Suppose we (incorrectly) model the rest energy of the proton m_pc^2 as...

An electron (mass m1 = 9.11 x 10-31 kg) and a proton (mass m2 = 1.67 x10-27 kg) attract each other via an electrical force. Suppose that an electron and a proton are released from rest with an initial separation d = 2.40 x 10-6 m. When their separation has decreased to 0.510 x 10-6 m, what is the ratio of (a) the electron's linear momentum magnitude to the proton's linear momentum magnitude, (b) the electron's speed to the proton's...

A proton (p) of mass 2.36-u(unified atomic mass units) traveling with a speed 4.93 x 104 m/s of has an elastic head-on collision with a helium (He) nucleus (mHe = 4.00 u) initially at rest. What is the velocity of helium nucleus after the collision? (As mentioned in Chapter 1, 1 u = 1.66 x 10–27 kg but we won’t need this fact.) Assume the collision takes place in nearly empty space.

Chapter 1 describes the evolution of operations from craft production to mass production to lean production, as modeled after the Toyota Production System (TPS). Using resources in addition to the textbook and those provided in this class, please investigate examples of other organizations that are attempting to adopt lean production. In particular, address "who" is adopting lean, "why" are they adopting lean, and "what" has been the result.
