Find the de broglie wavelength λ for an electron moving at a speed of 1.00 x 10^6m/s. (note that this speed is low enough that the classical momentum formula p=mv is still valid.) recall that the mass of an electron is me=9.11 x 10^−31kg, and planck's constant is h=6.626 x 10^−34j*s. express your answer in meters to three significant figures.

De broglie wavelength will be 0.727 nm

Explanation:

We have given speed of the electron

Mass of the electron

Plank's constant

We have to find the De Broglie wavelength

De Broglie wavelength is given by

So wavelength will be 0.727 nm

terd muffin is the correct answer

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
