The index of refraction of a material is the ratio between the speed of light in vacuum and the speed of light in that material:
where
n is the refractive index
is the speed of light in vacuum
v is the speed of light in the material
For sapphire, n=1.76, so if we re-arrange the previous equation and we use this value, we can calculate the speed of light in sapphire:
Answer:
Jim's kinetic energy is 54.67 J.
Explanation:
Given that,
Mass, m = 15 kg
Velocity, V = 2.7 m/s
We need to find the Jim's kinetic energy. We know that when the object is in motion, it has kinetic energy. This energy is given by :
E = 54.67 J
So, Jim's kinetic energy is 54.67 J. Hence, this is the required solution.
