(a) At what speed does its momentum increase by 1%?
(b) At what speed does its momentum increase by 10%?
(c) At what speed does its momentum increase by 100%?
Particle X has a speed of 0.850 c and
a momentum of 8.61×10-19kgm/s. What is the mass of the
particle?
What is the rest energy of the particle?
What is the kinetic energy of the particle?
What is the total energy of the particle?
A particle travels at 0.14c. By what percentage will a
calculation of its momentum be wrong if you use the classical
formula?
Express your answer using two significant figures.
p−prelprel = ? %
B- Repeat for
0.58c.
Express your answer using two significant figures
p−prelprel = ? %
If the momentum of a particle is doubled, what happens to its de
Broglie wavelength?
it decreases by a factor of 2-1/2
it doubles
it halves
it becomes slightly less than half
it slightly more than doubles
An 8kg mass is observed traveling with a speed of .08*c.
What is its classical momentum?
What is the relativisitic momentum?
What is the difference between the two values?
Repeat the problem for a speed of .2*c and .8*c
Sometimes it is convenient to construct a system of units so that all quantities can be expressed in terms of only one physical quantity. In one such system, dimensions of different quantities are given in terms of a quantity X as follows:[position] = [𝑋𝛼]; [speed] = [𝑋𝛽]; [acceleration] =[𝑋𝑝]; [linear momentum] = [𝑋𝑞]; [force] = [𝑋𝑟]. Then
what charge does a soil particle have and what does that mean in
terms of its ability to hold cations or anions? How can you
increase CEC (cation exchange capacity)?
An object has a relativistic momentum that is 7.3 times greater
than its classical momentum.
What is its speed?
Express your answer using two significant figures.
v=__________c
If a particle’s momentum uncertainty, what is the uncertainty in
its position. Very briefly, what does this result mean?
What is the Compton effect? What is measured in observations of
the Compton effect? How does this differ from the expectations of
classical physics? At what condition for incident radiation can the
effect be observed? What important property of light does the
Compton effect demonstrate? How does it give evidence of
electromagnetic radiation`s particle nature?
Is it possible to sketch the probability distribution of
momentum for a particle in the second excited state (n = 3) of an
infinite square well? If so, do it.
