The reason that the sun changes colors at sunset is because small particles and molecules in the atmosphere change the direction of light ray causing them to scatter and resulting in a beautiful sunset.
Answer:
Cumulative effect of two or more force can be found using Vector sum of all forces
Explanation:
Force is a vector quantity and in order to find the resultant of two or more forces we have to use the concept of vector addition
here we know that vector addition rule is given as
here we know that
= angle between two forces
so using this equation we can find the cumulative effect of two forces which are inclined at an angle with respect to each other
