We will apply the concepts related to energy conservation to develop this problem. In this way we will consider the distances and the given speed to calculate the final speed on the path from the sun. Assuming that the values exposed when saying 'multiply' is scientific notation we have the following,
The difference of the initial and final energy will be equivalent to the work done in the system, therefore
Here,
m = Mass
= Final velocity
G = Gravitational Universal Constant
M = Mass of the Sun
m = Mass of the comet
= Initial Velocity
Rearranging to find the final velocity,
Replacing with our values we have finally,
Therefore the speed is 75653m/s
Answer:
Solubility
Explanation:
Material becomes soluble in solvent and disappears.
Answer:
Velocity is a function of time and defined by both a magnitude and a direction. [1] Often in physics problems, you will need to calculate the initial velocity (speed and direction) at which an object in question began to travel. There are multiple equations that can be used to determine initial velocity. Using the information given in a problem, you can determine the proper equation to use and easily answer your question.

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.
