Water dude lol H²0 (dont you know?) #rhymes
H²o → Hydrogen [The 2 means there are two hydrogen atoms], Oxygen = H²O
The most appropriate unit to take the weight of a cow would be kilograms.
Meters are a unit of distance and are not applicable here
A gram is too small to use in this instance
Explanation:
To show - from E=mc²=hv show that wavelength=h/mv
Proof -
Given that,
E = mc²
E = hν
By equating both the equations, we get
mc² = hν
Because real particles do not travel at the speed of light, De Broglie submitted velocity ( v ) for the speed of light ( c ).
mv² = hν
Through the equation λ , de Broglie substituted v/λ for ν and arrived at the final expression that relates wavelength and particle with speed.
mv² = hv/λ
⇒λ = hv/mv²
⇒λ = h/mv
Hence showed.
