No, that was the exact question.

According to the de Broglie hypothesis, which of the following statements is applicable to the wavelength of a moving particle?

No, I just need the exact formula then I will know what to do from there.

What is the relationship between the wave function ψ(r,t) of a particle and the probability of finding the particle at position r at time t?

I don't know what formula to use.

The rest energy of an electron is 0.511 MeV = 8.2 x10-14 J. A positron is an electron with positive charge and the same rest energy. Within what time interval can we create and destroy an electron-positron pair without worrying about the conservation of energy? h = 6.626 × 10-34 J s.

These are the possible answers. a. 0.55c. b. 0.09c. c. 0.30c. d. 0.90c.

The nearest star to the Sun is Proxima Centauri, a very faint component of the Alpha Centauri system. It takes light 4.2 years to reach us from Proxima. In the light's own frame, how far away is it?

In a typical color television tube, the electrons are accelerated through a potential difference of 25,000 Volts. What speed do the electrons have when they strike the screen? (qe = 1.6 x10-19 C, me = 9.1 x10-31 kg)

thank you very much!

ok so my palm faces east since it goes left to right, my thumb is pointing down. but down would mean positive, so I am assuming it goes to the top right?

Assume that a uniform magnetic field is directed into this page. If an electron is released with an initial velocity directed from the left edge to the right edge of the page, which of the following describes the direction of the resultant force acting on the electron? I think it would come...

ok, thank you very much its appreciated

thank you very much, i just solved it

Why is there a minus sign in the formula Δp/Δt = −ΔEP/Δs? Is it because the objects are accelerated toward or away from a higher potential, or is it something else? If anyone could help me, thank you!
