Question

An object has a mass of 1.67 x
10^{-27}kg and a
kinetic energy of 2.323 x 10^{-17}J. use De Broglie’s equation to find the
wavelength associated to this object.

Answer #1

Two
protons (resting mass M=1.67*10-27kg) move in opposite directions
at the same rate. After collision, the protons are retained, but
the collision results in a new particle having a rest mass of
m=2.75*10-28kg.
1a) Calculate the kinetic energy of the proton in MeV

1. A neutron has a rest mass of 1.68 × 10−27kg. How much kinetic
energy would it possess if it was travelling at 0.800c?
2. How much energy would be required to produce a kaon particle
at rest with a rest mass of 8.79 × 10−28kg?
3. The Sun radiates energy away at a rate of 3.9 × 1026W. At
what rate is the Sun losing mass due to this radiation?
4. How many 100.0W light bulbs could be powered...

A proton (mass 1.67 × 10 −27kg) is moving at
1.30 ×10 −6m/s directly toward a stationary helium
nucleus (mass 6.64 × 10 −27kg).
a)After a head-on elastic collision, what is the proton's
velocity?.
b)After a head-on elastic collision, what is the helium's
velocity?

A neutron (m=1.67×10?27kg) moves with a speed of 0.91 c.
Part A What is its total energy?
Part B what is its rest energy?
Part C What is its kinetic energy?

Compare the wavelengths of an electron (mass = 9.11*10^-31 kg)
and a proton (mass = 1.67*10^-27 kg), each having (a) a speed of
4.33*10^6 m/s and (b) a kinetic energy of 7.63*10^-15 J. Please
give in scientific notation for both.
a) electron wavelength=____*10^__m
proton wavelength=____*10^__m
b) electron wavelength=___*10^__m
proton wavelength=____*10^m

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 = 3.50 x 10-6 m. When their separation has
decreased to 1.40 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...

An infinitely long line of charge has linear charge density
4.00×10^−12 C/m. A proton (mass 1.67×10^−27kg, charge +1.60×10^−19
C) is 18.0 cm from the line and moving directly toward the line at
3.80×10^3 m/s. How close does the proton get to the line of charge?
Please show all steps CLEARLY so I can follow and understand how to
derive the equation and solve for the answer with my given values.
Thank you so much in advance!!!

What is the wavelength, in meters, of an alpha particle with a
kinetic energy of 8.00•10^(-13) J? (Mass of an alpha particle=
4.100150 AMU. 1 AMU = 1.67•10^(-27) kg)

An object has a kinetic energy of 254 J and a momentum of
magnitude 24.8 kg · m/s.
(a) Find the speed of the object. m/s
(b) Find the mass of the object. kg

1) Find the uncertainty in kinetic energy. Kinetic energy
depends on mass and velocity according to this function E(m,v) =
1/2 m v2. Your measured mass and velocity have the
following uncertainties 0.01 kg
and 0.37 m/s. What is is the uncertainty in
energy, , if the measured mass, m = 0.68 kg and the
measured velocity, v = 1.09 m/s? Units are not needed in your
answer
2) The propagation of uncertainty formula for the equation y =
ax^2 is
where ,and ....
