1. Communication
In early ages people were using letters to communicate between them. Now days instantly we can call one person from anywhere, these are based on optical fiber communication and it is an application of physics.
2. Transportation
We can travel from place to anther place by aeroplane , these technologies are introduced after advancement in physics.
3. Construction
Earlier people used to stay in small houses, now days apartments with many number of storeys are built by considering all the forces coming on the structure.
4. Medical Department
The invention of many equipment increased the health of humans.
5. Weather forecasting
The prediction of weather considering all the available factors, prediction of natural disasters all are application of physics.
To solve this problem it is necessary to apply the concepts related to the concept of superposition and the fringe separation for double slit experiment.
The equation can be written as
Where
= Distance between fringes
x = distance between slits and screen
d = Distance between slits
= Wavelength
Our values are given as
d= 0.08mm
x =3m
In this way replacing in the equation,
Therefore the distance between the fringes is 2.37cm
PART B) For the case in which it is submerged in water it is necessary to apply the relationship of the fringes with the index of refraction therefore
B. a sound wave that he could just barely hear
Answer:
It can cause an object to accelerate.
It can cause an object to stop moving.
It can cause an object to start moving.
It can cause an object to change directions.
Explanation:
When the velocity of an object is increased in the same direction, the object is said to have positive acceleration. If it increases its velocity in a direction that is opposite to the original direction, it is negative acceleration.
When an object that's already moving is made to stop, it is said to have decelerated. Deceleration is negative acceleration.
When an object at rest is made to move by applying a force, it is said to have accelerated to some final velocity, during its motion for some duration.
An object at rest will remain at rest is said to have no net force acting on it.
180+156=336
4+3=7
336/7=48mph
