A 0.22 caliber handgun fires a 1.9g bullet at a velocity of 765m/s. Calculate the de Broglie wavelength of the bullet. Is the wa
ve nature of matter significant for the bullets?
1 answer:
Answer:
- de Broglie wavelength of the bullet is 4.56 x 10⁻³⁴ m
- The value of the wavelength shows that wave nature of matter is insignificant for the bullet because it is larger than particles.
Explanation:
Given;
mass of the bullet, m = 1.9 g = 0.0019 kg
velocity of the bullet, v = 765 m/s
de Broglie wavelength of the bullet is given by;
where;
h is Planck's constant = 6.626 x 10⁻³⁴ J/s
λ is de Broglie wavelength of the bullet
Thus, this value of the wavelength shows that wave nature of matter is insignificant for the bullet because it is larger than particles.

Answer:
149.8Hz
Explanation:
V=I.(XL).........{1}
where (XL) is inductive reactance
(XL) =2πfL......... {2}
V= 41.5, l= 4.5, L= 9.8* 10^-³
take π to be 3.14
(XL) = V/I
= 41.5/4.5
= 9.22
f = (XL) /2πL
= 9.22* 10^³/6.28* 9.8
=149.8
Answer:
There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.
