What is the de Broglie wavelength of a bullet of mass 0.030 kg traveling at 540 m/s? Planck's Constant is 6.63 × 10−34 J⋅s.

4.1 × 10−35 m
3.5 × 10−35 m
2.2 × 10−34 m
1.7 × 10−34 m

I believe the answer is 4.1 * 10^-35 m

Explanation:

I worked out the problem using the equation for this kind of wavelength.

Since I don't have the special keybind for it, ? will be the wavelength.

? = h/p

In this case, h = Planck's constant, which is 6.63 * 10^-34 J*s.

P = momentum, which is mass * velocity.

M (mass) = 0.030 kg.

V (velocity) = 540 m/s.

0.030 * 540 = 16.2.

P = 16.2

? = h/p

? = (6.63 * 10^-34) / 16.2.

? = 4.0925 * 10^-35.

? = 4.1 * 10^-35.

The wavelength is 4.1 * 10^-35 m.

a and c

explanation:

both a and c are correct answers to my knowledge, it's been a bit since i've done anything related to magnetic fields, but it should be right.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
