A beam of electrons strikes a double slit, with the slit separation of 130 nm. The first-order diffraction maximum is seen at an angle of 5 degrees away from the beam's direction. What was the speed of the electrons

The speed of electron is 891.8

Explanation:

Given :

Wavelength m

According to the uncertainty principle,

Where difference in length means wavelength, difference in momentum,

We know that

Put value in main equation,

                    ( ∵ )

Therefore, the speed of electron is 891.8

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )
