<span>3640 m/s
The de Broglie wavelength of a particle is expressed by the equation:
λ = h/p
where
λ = wavelength
h = Planck constant
p = momentum
so let's solve for momentum and the substitute the known values and calculate:
λ = h/p
λp = h
p = h/λ
p = 6.62607004x10^-34 Js/2x10^-7 m
p = 6.62607004x10^-34 kg*m^2/s^2 * s/2x10^-7 m
p =3.31303502x10^-27 kg*m/s
Now momentum is defined as mass times velocity. And the mass of an electron is 9.10938356Ă—10^-31 kg. So
p = mv
p/m = v
3.31303502x10^-27 kg*m/s / 9.10938356Ă—10^-31 kg = v
3.63694754774384x10^3 m/s = v
Rounding to 3 significant figures gives 3.64x10^3 m/s or 3640 m/s. That velocity is low enough that we don't need to worry about relativistic effects.</span>
Answer:
480 mL
Explanation:
Ideal gas law states:
PV = nRT
At constant pressure, nR/P is constant. Therefore:
V / T = V / T
420 mL / 220 K = V / 250 K
V ≈ 480 mL
If we will connect the resistors 2ohms, 3ohms, 5ohms in series and the 10ohms resistance parallel then we get equivalent resistance of 5 ohms.
The equivalent circuit is,
R equivalent for the series connection is,
The equivalent resistance is 5 ohms.
So your friend is saying true.
