Answer:
The distance of first minimum from central maxima is 4.25 m
The spacing between maxima in sound intensity is 8.5 m.
Explanation:
Given that,
Distance D= 15 m
Frequency = 200 Hz
distance between slits a=3 m
We know that,
The width of fringe,
(a). We need to calculate the distance of first minimum from central maxima
Using formula for distance
Put the value into the formula
(b). We need to calculate the spacing between maxima in sound intensity
Using formula for the distance of first maxima
Hence, The distance of first minimum from central maxima is 4.25 m
The spacing between maxima in sound intensity is 8.5 m.
The person walking down the sidewalk follows the newton's third law of motion.
Explanation:
- A person is able to walk down the sidewalk by using the reaction forces from the ground.
- In simple term, feet pushes the ground and the reaction forces makes the feet able to walk.
- Another important force included in the walking mechanism is friction. With out friction one cannot walk down the sidewalks.
- Hence the forces involved in the walking of a person down the sidewalk are:
- Friction force
- Action and reaction force between ground and person's feet.
