Answer:
0.459 m.
Explanation:
To calculate the height, use 3rd equation of motion as
Here v is the final velocity, u is the initial velocity, g is the acceleration due to gravity and h is the height.
As ball moving up so acceleration due to gravity becomes negative i.e -g and at maximum height v = 0.
Therefore equation becomes,
Given u = 3 m/s and g = 9.8 m/s^2.
Substitute the given values, we get
h = 0.459 m
Thus, the height of hill is 0.459 m.
Explanation :
In Newton's prism experiment, a ray of white sunlight is passed to the prism. It is observed that the light gets refracted at different angles and different colors spread.
Sunlight is made up of seven colors. The colors are the same as the colors seen in the rainbow. The colors are :
- Violet
- Indigo
- Blue
- Green
- Yellow
- Orange
- Red
So, the correct option is (c) " White sunlight is made up of all the colors of the visible spectrum ".
