Speed of light:
The value of the speed of light in a vacuum is now precisely defined as .
Explanation:
1. Light waves travel the fastest through air and the slowest through other materials like glass or water.
2. Speed of light in a medium of refractive index n is given by:
, or . Thus, for more v, n should be less.
speed of light in the medium, = speed of light in vacuum.
3. Air has the lowest refractive index of the options presented.
4. Thus, the light will travel faster in the air.
Therefore, the correct option is option A.

A science student is riding on a flat car roof train that is traveling at a constant speed of 10 mph on a straight horizontal track. The student throws a ball into the air along a path that he just made to make an initial angle of 60 degrees with the horizontal and to be in line with the track that the student's professor, who is standing nearby, observes the ball rising. How high does the ball rise vertically?

The house is losing heat to the outside air through the walls and windows at a rate of 40 MJ/J, while energy generated within the house from the people, lights and appliances amount to 6000kJ/h. For a COP of 2.4, find the power input to the heat pump
