I've been thinking about this one problem for 2 days. The book does not give enough examples for me to figure it out. HEre is the problem.

A panel is being organized. You need to arrange a list of participants 4 administrators and 4 students. A) in how many ways can you list them if administrators must sit together in a group and students in a group? B) In how many ways can you list them if you must alternate students and administrators?

The answer on the back of the book says its 2*4!*4! = 1152. However it does not specified if this applies to part A) part B) or both. Plus I have no clue how they got this arrangement. Please provide how you came up with your answer. And yes its part of my homework but I just have no clue on how to solve this one.

i want to know exactly what interaction is there between the magnetic field of a conductor and the magnetic field of the magnet that makes the conductor to experience the Lorentz force when placed perpendicular to the magnetic feild and also why this force does'nt apply when the conductor is placed parallel to the magnetic field.

Since the ~30 years from my birth sound waves (from my first movements and cries) have travelled 325,346,400km - or about 1000 light seconds.

Light from me (my light cone) has travelled 30 light years.

Now I believe that from my frame of reference, the light has not experienced the passing of time - is that right? - but the sound has (as time slows down as one approaches light speed.

Anyway, just as light reaching us from stars light years away tells us about what has happened in the past, if we could reverse the light from my birth, in it's direction (say by a hypothetical but improbable mirror), in 30 years time we would see the event over again - and be looking back 30 years into the past.

But with the sound, if we could encode it's information into light wavicles, we would be looking only 1000 seconds into the past - or so it would seem.

It this apparent oddity explained by the faster rate at which time passed for the sound (ie. less time dilation)

All birds lay eggs. There are no avian species with a reproductive system similar to placental mammals, and there are no ovoviviparous species that retain the eggs internally until they hatch. Briefly describe how this phenomenon would be approached from a proximate vs. an evolutionary viewpoint. Help me with this! Proximate vs. evolutionary viewpoint???

hi, i'm a medicine student and for a project we have to do a dissection. i have an elbow, and i have to show the muscles and ligaments of the elbow, without cutting away the nerves and vessels.

i have just obtained the specimen, however my tutor wont be available till next thursday (today is monday here). i would like to begin as i am already late (project ideally must be ready in 3 weeks time). i thought i would begin by opening the skin and removing the underlying fat.

the problem is that i dont know what instruments to use. if anyone out there knows, please tell me!!! i have a scalpel - i guess this is used to cut the skin, right??? then what do you do to remove the fat???

another problem, which i dont know if it is a problem or not is that my specimen is 'fresh'. that is, it has blood (dry, not oozing out) and it is not hard, like the specimens my colleuges have. this is because there were not enough cadavers and i got a specimen which happened to be lying around.

Why is it not possible to make a machine/generator that once started on another fuel can run itself by creating its own energy.

Like the 2 magnets that give perpetual motion.
