On the off chance that u know the condition I = NEVA where N= no. thickness of electrons, E= charge on a solitary electron, V=drift speed ,and A=area of cross-segment.
since the widths are same , the zone of cross-segment must be same and thusly the float speed likewise will be the same
b) as u know current streams from higher to bring down potential.The electrons will spill out of lower potential to higher potential. Higher potential suggests higher potential vitality and accordingly potential vitality must increment.
Answer:
(6.675 × 10⁶) m
Explanation:
A body vibrating in simple harmonic motion has its frequency related to the spring constant and mass of the body through the relation
f = (1/2π) √(k/m)
k = 2233 N/m
m = mass of one molecule of Nitrogen = 28.0 g = 0.028 kg
f = (1/2π) √(2233/0.028)
f = 44.945 Hz
And the photons that'll excite the molecule to the next state must at least have this frequency (f = 44.945 Hz)
For waves, the velocity (v), frequency (f) and wavelength (λ) are related through the relation
v = fλ
v = speed of light (since it's a photon) = (3 × 10⁸) m/s
λ = (v/f) = (3 × 10⁸)/44.945 = 6674824.8 m = (6.675 × 10⁶) m = (6.68 E6) m
I believe the answer is true
Delta means change usually
It’s true
an atom as a whole is electrically neutral
