Answer #1

A certain rifle bullet has a mass of 8.13 g. Calculate the de
Broglie wavelength of the bullet traveling at 1337 miles per hour.
Physical constants can be found here.

Calculate the linear momentum, and the de Broglie wavelength
of:
a) a 0.75 kg bullet that is fired at a speed of 100 m /
s,
b) a non-relativistic electron with a kinetic energy of 2.0
eV, and
c) a relativistic electron with a kinetic energy of 208
keV.
!!!! # !! Remember that for relativistic particles: ? = ? ? +
? "? and ? = ?? = ? + ?" ?, the mass
of the electron is 9.11...

If the De Broglie wavelength of an electron is equal to 450
nm calculate the velocity of the electron. Assume that the
electron's speed is non-relativistic.

If the kinetic energy of an electron is 170 eV,
calculate its De Broglie wavelength. For this non-relativistic
electron you must first calculate its velocity from the general
kinetic energy equation. Then you can find the De Broglie
wavelength of the electron.

Calculate the de Broglie wavelength of (a) a
0.613 keV electron (mass = 9.109 × 10-31 kg),
(b) a 0.613 keV photon, and (c) a
0.613 keV neutron (mass = 1.675 × 10-27 kg).

A. The mass of an electron is 9.11×10−31 kg. If the de Broglie
wavelength for an electron in a hydrogen atom is 3.31×10−10 m, how
fast is the electron moving relative to the speed of light? The
speed of light is 3.00×108 m/s. Calculate your answer as a
percentage.The solution was .732% B. The mass of a golf ball is
45.9 g . If it leaves the tee with a speed of 70.0 m/s , what is
its corresponding wavelength?...

(a) An electron has a de Broglie wavelength of 2 pm. Calculate
the relativistic velocity of the electron in terms of c.
(b) A beam of 1.9 eV electrons bombards a sample of hydrogen. If
a spectral line of the Balmer series is observed, calculate the
initial energy level, n-i of the electron.

A He atom with a mass of 6.65×10−27 kg has a de
Broglie wavelength of 4.3×10−12 m. What is the velocity of the
He atom, in meters per second?
Use 6.626×10−34kg m2s for Planck's constant.
Your answer should include two significant figures.

Calculate the de Broglie wavelength of helium nucleus (mass = 6.64
x 10^-27 kg) moving at a velocity of 2.54 x 10^7 m/s
A. 6.57 x 10^-14 m
B. 3.96 x 10^-15 m
C. 8.68 x 10^-59 m
D. 4.55 x 10^8
E. 8.64 x 10^-16

A rifle bullet with mass 15.0 g strikes and embeds itself in a
block of mass 1.500 kg that rests on a frictionless, horizontal
surface and is attached to a coil spring. The spring was relaxed at
the beginning. The spring constant is 550 N/m. The initial velocity
of the bullet was 700 m/s. The impact compresses the spring by x
(see figure below). 1) Find the magnitude of the block's velocity
(with the bullet stuck inside) after the impact...
