Steel is more dense because it’s heavy while water is light
Answer:
The correct option is;
Still constant
Explanation:
The relative refractive index ₁n₂ between the two medium can be as follows;
![_1n_2 = \dfrac{The \ speed \ of \ light \ in \ medium \ 1}{The \ speed \ of \ light \ in \ medium \ 2} = \dfrac{c_1}{c_2}](https://tex.z-dn.net/?f=_1n_2%20%3D%20%5Cdfrac%7BThe%20%5C%20speed%20%5C%20of%20%5C%20light%20%5C%20in%20%5C%20medium%20%5C%201%7D%7BThe%20%5C%20speed%20%5C%20of%20%5C%20light%20%5C%20in%20%5C%20medium%20%5C%202%7D%20%20%3D%20%5Cdfrac%7Bc_1%7D%7Bc_2%7D)
Therefore, given that the speed of light in medium 1 is constant and the speed of light on medium 2 is also constant, the relative refractive index ₁n₂ = c₁/c₂ is always constant.
Answer:
1.40 m/s^2
Explanation:
Given data
Velocity= 17.4 m/s
time= 12.4 seconds
We want to find the acceleration of the rock
We know that
acceleration = velocity/time
Substitute
acceleration= 17.4/12.4
acceleration=1.40 m/s^2
Hence the acceleration is 1.40 m/s^2
Answer:
Explanation:
The equivalent resistance for three resistors connected in parallel is given as
(1/R)=(1/R₁)+(1/R₂)+(1/R₃)
now we.need to.insert the value of 3 resistances but only 2 are given in the question.
