The object will move 5 meters per second (5m/s)
What does thrice mean not being mean or anything just saying so I can help with the question
Option (b) is correct.The index of refraction for the glass is 1.52
Explanation:
velocity of light in vacuum= C= 2.99 x 10⁸m/s
Velocity of light in glass = V= 1.97 x 10⁸m/s
The refractive index is given by n=
n= 2.99 x 10⁸/1.97 x 10⁸m/s
n= 1.52
Thus the refractive index of glass is 1.52
Kinetic Energy is defined by 1/2 times the mass times the velocity squared.
KE = (1/2)mv2
The last sentence is a little vague.
However, I will assume that by the last sentence you meant
![Reaction~Rate=[CH_3Cl][H_2O]](https://tex.z-dn.net/?f=Reaction~Rate%3D%5BCH_3Cl%5D%5BH_2O%5D)
The reaction order respective to any substance is the value of the exponent on that substance in the Reaction Rate equation.
We see that the exponent on both the substance is 1 so the reaction order with respect to each substance is 1.
