Answer:
Explanation:
When two coherent light beams travel different paths and arrive at a point , there will be difference in the length of path travelled by them . If this difference is zero then both will reinforce each other and their brightness will add up . Hence there will be constructive interference .
If their path difference is not zero but it is equal to odd multiple of their half wavelength like λ / 2 , 3 λ / 2 , 5 λ /2 , 7 λ /2 etc , then instead of reinforcing each other , they will destroy each other . This is called destructive interference . As a result of it , darkness will prevail at the point where they meet or interfere.
At a constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.
The force applied to an object can be determined by applying Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.
F = ma
where;
- <em>m is the mass of the balloon</em>
- <em>a is the change in velocity per time</em>

The mass of an object is inversely proportional to the rate of change motion of the object.
Thus, we can conclude that at constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.
