Elliptical and Spiral have some similarities, they both are huge and contain lost of dust and also they are held by gravitational forces.
Field in this context refers to a region of the space to which corresponds a value.
There is a gravitational field around the earth, because a mass m placed at any point around the earth will be atracted (gravitational force) by it.
There is an electric field in a point when a charge placed there feels an electric force.
The gravitational field is proportional to the value of the mass of the object that produces it.
The electric field is proportional to the magnitude of the charge of the particle that produces it.
The gravitational field is always attractive. The electric field may be attractive or repulsive.
Both fields are proportional to the inverse of the squared distance.
The magnetic field is created when a charge is in movement,i.e a charge in movement will create a magnetid fiedl around it that will act and create a magnetic force over other charge also in movement.
The magnetic field is proportional to the product of the charge times its velocity and inversely proportional to the squared distance. The force generated my be attractive or repulsive.
The Young modulus E is given by:
where
F is the force applied
A is the cross-sectional area perpendicular to the force applied
is the initial length of the object
is the increase (or decrease) in length of the object.
In our problem,
is the initial length of the column,
is the Young modulus. We can find the cross-sectional area by using the diameter of the column. In fact, its radius is:
and the cross-sectional area is
The force applied to the column is the weight of the load:
Now we have everything to calculate the compression of the column:
So, the column compresses by 1.83 millimeters.
"Traditionally, physical science courses are categorized into four areas: physics, chemistry, earth sciences, and space sciences. It is important to understand that the arbitrary divisions of specialized knowledge are integrated into a basic overview of the physical laws that govern our universe." - Cameron University
Answer:
the pressure will increase.this will cause the molecules of the gas will move faster and thats why the pressure or force increase the volume is the same
