Answer:
The precision at which the number was measured
Explanation:
The number of digits that you use to record a measurement indicates the precision of the measurement.
It is B) Wavelength, because it measures the "length" between "waves", therefore, wavelength.
Answer:
Explanation:
Energy, E = 4.75 x 10^-19 J
Energy, E = hc/λ
where, λ is the wavelength, h be the Plank's constant and c be the velocity of light.
h = 6.63 x 10^-34 Js
c = 3 x 10^8 m/s
λ = (6.63 x 10^-34 x 3 x 10^8) / (4.75 x 10^-19)
λ = 418.73 nm
So, the colour of light should be violet.
Explanation:In exothermic reactions, increase in temperature decreases the equilibrium constant, K, whereas, in endothermic reactions, increase in temperature increases the K
