3.51 × 10^-7m
Explanation:
Refractive index = wavelength of the light in air ÷ wavelength in the medium
wavelength in the medium = wavelength of the light in air ÷ refractive index
= 5.4 * 10^-7 ÷ 1.54
= 3.51 × 10^-7m
Acceleration = speed/ time
a = Δv/Δ t
as Δv = v₂ - v₁ / t
a = 50m /s - 0 m/s / 60m
= 50m/s / 60m
= 0.834s⁻¹
Explanation:
wait I will give it ur answer
In endothermic reactions energy in the form of heat is given
The similarity is that they both are types of bonds in molecules.
Ionic bonds are between a metal and a nonmetal.
Covalent bonds are between two nonmetals.
