The latent heat of fusion of water is 344 j/p.This will take 344x300 or 100200 J to melt the ice. once it melted its at oc
use a = (v1-v2)/t so u would put 14 (initial velocity or v 1) - 6 (the v2) and divide all of that by 4 seconds to get 2m/s/s as your acceleration
Yes so the materials that it holds is
The angle of the incidence (T) = 40°
Angle of refraction (r) = 26°
→To find the speed of light in the material
From shell's law, we know
n: sin i/sin = speed of light in air/Speed of light in the medium
Sin 40°/sin 60° = 3×10⁸/V
V = 3 × 10⁸× sin 26°/sin 40°
→ V medium = 2 × 10⁸ m/s.
