Theoretical study of law, principally by philosophers but, from the twentieth century, also by social scientists. Scholars of jurisprudence, also known as jurists or legal theorists, hope to obtain a deeper understanding of legal reasoning, legal systems, legal institutions, and the role of law in society.
After doing some research on Wiki, Google, and Easyscienceforkids, I have come to a conclusion that:
Mass: 5.972 * 10^24 kg
Radius: 3958.8 mi
Distance from the sun: 92.96 million mi
Time and velocity are both vectors T/F
Answer:
(a). Index of refraction are 
= 1.344 & 
= 1.406
(b). The velocity of red light in the glass 
2.23 ×
The velocity of violet light in the glass 
2.13 ×
Explanation:
We know that
Law of reflection is
Here
= angle of incidence
= angle of refraction
(a). For red light
1 × 
= × 
= 1.344
For violet light
1 × = × 
= 1.406
(b). Index of refraction is given by
= 1.344
2.23 ×
This is the velocity of red light in the glass.
The velocity of violet light in the glass is given by
2.13 ×
This is the velocity of violet light in the glass.
The solid cylinder reaches the bottom first.
A solid object will always roll down the ramp faster than a hollow object of the same shape regardless of their exact mass or diameter.
The solid cylinder has a lower moment of inertia than the hollow one does. Although they have the same mass, all the hollow cylinder's mass is concentrated around its outer edge so its moment of inertia is higher.
The velocity would be greater for the material with radius of gyration k is lower of for which the moment of inertia is lower. Solid cylinder with k as 1/2 will have greater velocity as compared to hollow cylinder which has k as 1. As they have same mass and radius their energies at both the levels would remains same including the potential energy and energy lost due to friction.
