The required value of the index of refraction of glass is 1.5.
Given data:
The speed of light in a vacuum is, 
.
The speed of light in a glass is, 
.
Light has the tendency to travel from one medium to another, then the difference between the speeds of light in various mediums is determined by a term, known as the index of refraction. The mathematical expression for the index of refraction of glass is,
n = c / v
Solving as
Thus, we can conclude that the required value of the index of refraction of glass is 1.5.

Answer: on jupiter you would weigh the most and on mars you would weigh the least
Explanation:
Answer: The ice absorb 6671.1 kJ of thermal energy.
Explanation:
The conversions involved in this process are :
Now we have to calculate the enthalpy change.
where,
= enthalpy change = ?
m = mass of ice = 20.0 kg = 
(1kg=1000g)
n = number of moles of ice= 
= enthalpy change for fusion = 6.01 KJ/mole = 6010 J/mole
Now put all the given values in the above expression, we get
(1 kJ = 1000 J)
Therefore, the enthalpy change is, 6671.1 kJ
