number of students moving left to right
N
R-L number of students moving right to left
In a specified time interval., if the time interval is very
small that is if the time interval is approaching zero
t tends to zero then the difference is called derivative.
It is represented with dN/dt.
The additional condition required is change should be continuous.

Linear charge density λ Problem 3; ll examples of Gauss's law have used highly symmetric surfaces where the flux integral is either zero or EA. Yet we've claimed that the net flux Ф,-Qin/eo is independent of the surface. The figure on the right shows a cube of edge length L centered on a long thin wire with linear charge density A. The flux through one face of the cube is...

2. In class we considered a mass m connected to a pair of identical springs with spring constant k. One spring is connected to the left side of m and the other is connected to the right side. Initially, the springs are at their equilibrium lengths ro and the two springs and the centre of m are all aligned with the r-axis. The mass is on a frictionless horizontal surface. The ry-plane is horizontal. m4 co . In class, we...

L/2 L/4 L/2 L/4 P/2 P/2 3 pt. Loading 4 pt. Loading 1. The schematics above show two common mechanical testing geometries - a 3 point loaded specimen and 4 point loaded specimen. The samples you would test in these geometries would be called "flexure" samples. P is the load measured by the load cell Samples would actually be longer than L but the contact points determine the loading profile...

18 A flexible rope of mass m and length L slides without friction over the edge of a table. Let x be the length of the rope that is hanging over the edge at a given moment in time (a) Show that r satisfies the equation of motion/dt2 -gr/L. Hint: Use F-dp/ dt, which allows you to handle the two parts of the rope separately even though mass is moving out of one part and into the other (b) Give...

ahhh...debits and credits, easily one of the hardest concepts for beginning accounting students to get a handle on. Now for the good news, by the time you finish this course you will be doing debits and credits in your sleep. (OK, put down the phone. Don't drop the class. I promise this will in no way effect your sleeping patterns:-) Please, please, please watch the chapter 2 overview video for a discussion of debits and credits before responding to this...

Please derive these equations and break them down into steps .
thank you very muvj
Pumping from a Standing Position The pumped swing is modeled as a pendulum with variable length L. The rider is modeled as a point mass m, and L is the distance from the rider's center of mass to the fixed swing support point O. Conservation of angular momentum for a point mass undergoing plane motion is where H is the angular momentum of the body...

Im kinda lost in this sample problem im trying to study..
could someone pls clarify my questuon i wrote in green..
My question is why they used that formula or can u relate that
to the formula i shown to u from my book. Whyvthey ignore that part
pf the formula for this problem??
Also i dont understand the limit for 1/r could someone pls
help explain..
Any helpful help would be appreciated..
