Answer:
electron λ = 12.5 nm
, bullet λ = 1.11 10⁻³³ m and golf ball λ = 4.7 10⁻³⁴ m
Explanation:
The Broglie wave duality principle states that all matter has wave and particle properties, it is expressed by the equation
p = h / λ
Where lam is called broglie wavelength
Let's use the definition of momentum
p = mv
Let's calculate the wavelengths
-Electron
mv = h /λ
λ = h / mv
λ = 6.63 10⁻³⁴ / (9.1 10⁻³¹ 5.81 10⁶)
λ = 1.25 10⁻¹⁰ m
λ = 12.5 nm
This is the X-ray region
-bullet
λ = 6.63 10⁻³⁴ / (1.90 10⁻³ 313)
λ = 1.11 10⁻³³ m
It is too small, only particle characteristics are observed
-Golf ball
λ = 6.63 10⁻³⁴ / (4.50 10⁻² 31.3)
λ = 4.7 10⁻³⁴ m
Too small, only particle characteristics are visible
Hey there,
Electric cells we use usually carry limited voltage. Here's an example: 1.5V. Really, there is no chance of any shot circuit. that's why MCB and fuse wires are not used in their circuit
.
:)
Explanation:
KE = KE
½ mv² = ½ mv²
½ (1.88 g) v² = ½ (230.5 g) (58.5 m/s)²
v = 648 m/s
Answer:
A natural resource is something found in nature that people use.
