Two objects are said to be in parallel when they both act on the system in the same way, e.g., two forces are in parallel if they have the same direction and are applied at the same point. A light rod of length 40.1 cm is held aloft from the ceiling by two springs attached to its ends. The left spring has a stiffness of 20 kg/s2 and equilibrium length of 27.9 cm and the right spring has a stiffness of 21.8 kg/s2 and equilibrium length of 21 cm. A ring weighing 637 g is placed 21.8 cm from the left spring.
(a) How much does the left spring stretch?
(b) How much does the right spring stretch?
Now, mathematically slide the ring to the point that levels the
rod.
(c) At what distance from the left spring should you place the ring
in order for the rod to be level?
(d) How far from the ceiling is the rod when it's level?
Now consider modelling the two springs as if there were only one
spring that held the ring aloft.
(e) What is the equilibrium length of the spring?
(f) How much does the spring stretch when the ring is placed on it?
(g) What is the stiffness of the spring?

Two parallel conducting plates are oriented in an ? − ?
coordinate system. The plates are separated by a distance ? = 0.05
?, and the origin of the coordinate system is halfway between the
plates. The plate separation is very small compared to the size of
the plates. The left plate is at a potential ?L = 50 ?,
and the right plate is at a potential ?R = 10
?.

Newton said that objects continue moving if no forces
are acting on them, but his predecessor Aristotle said that a force
was necessary to keep an object moving. Why does Aristotle’s theory
seem more plausible, even though we now believe it to be wrong?
What insight was Aristotle missing about the reason why things seem
to slow down naturally? Give an example

When an individual is standing still on two feet, they are said
to be stable. 1) Discuss the how the movement of the center of
gravity over the person’s feet in response to an external torque
relates to stability. 2) Mechanically speaking, what will happen if
the center of gravity moves outside of this base of support? 3)
Using the Newton’s third law, what are some things you can do in
this scenario to prevent yourself from falling? Give specific...

Create a windows application that
contains two TextBox objects and two Button objects. One of the
TextBox objects and one of the buttons are initially invisible. The
first textbox should be used to input a password. The textbox
should be masked to some character of your choice so that the
characters entered by the user are not seen on the screen. When the
user clicks the first button, the second TextBox object and button
object should be displayed with a...

When two plane mirrors are parallel, such as on opposite walls
in a barber shop, multiple images arise because each image in one
mirror serves as an object for the other mirror. An object is
placed between parallel mirrors separated by 25 cm. The object is
15 cm in front of the left mirror and 10 cm in front of the right
mirror.
(a) Find the distance from the left mirror to the first four
images in that mirror.

Two infinite thin sheets of current are parallel to each other.
Both sheets conduct a linear current density of 8 A/m, but the top
sheet current is out of the page, while the bottom sheet carries
current into the page: A 8 A/m (out) B 8 A/m (in) C A. Calculate
the magnetic field at point ‘B’, halfway between these sheets. B.
Calculate the magnetic field at a point ‘A’, 1 meter above the top
plate. C. The bottom plate...
