I'll have to find the issue. I would be particularly interested to see whether MDMA has been in tried with connection of Aspergers patients. MDMA and simuilar compounds are as far as I know the only known chemical empathogens, and may be of great value in developing these capacities. Come to...
Not in the US. It is a scheduled I substance which means it has no redeeming medical value whatsoever.
Numerous psychotherapists and researchers have enjoyed considerable success with unapproved methods. And really I should not imply that such success is limited to issues of the mind. Does...
Hee, hee poorly worded.
Words are way too often a lousy substitute for math and a diagram. So correct that which should read whether the rays reflected from the fish were directed above or below his eyes before hitting the surface.
Can you do what the question asks and draw a diagram of the light rays striking the fishermans eyes? What happens at the surface?
Is it bent towards or away from the fisherman? If you know that, it becomes a problem in geometry.
In this case, yes, but what if the next interval was 6.1 seconds. Profs have bbeen known to do such things, esp physics profs!:smile:
So knowing the velocities is a necessary skill on the third day.
Once the spring has reached a standstill and commences to retract, the SHM eqns should work. It makes no difference how that distance from equilibrium was reached.
From your comments, I believe you may have computed the swing back time, but neglected the time required to slow the bus?
Edit...
Indeed. And those patents really operative in the US only as modafinil has been available as a generic for quite some time in other countries. To me, this case along with many others sugggests that a new paradigm for bringing a drug to market here in the US, or even broadening indications for an...
Most of these experiments I recall were done in dark adapted volunteers using all of the eye. But in theory, all you need is capture of one photon by one rhodopsin photopigment molecule which sets into motion a biochemical cascade with gain measured in the millions.
It really seems to be a safer alternative for ADHD than the regular stimulants--but still an off label use as far as I know. One case of Stevens-Johnson syndrome in a study of 1000 patients stopped progress towards getting the indication. Yet the FDA still approves the use of various stimulants...
The force is going to be applied in line with the initial angle which can be found as you suggest:
tan (theta)= Vy/Vx
Don't have time to check your work, but you can always test it by trying it, ie
Find a. Multiply by 0.11 sec to get Vinitial. Then decompose into to Vy and Vx. Vy you...
Modafenil--the non-amphetamine speed with lots of disclaimers re we know not how it works! Careful on that one--I've prescribed it for jet lag and narcolepsy. To say it causes psychosis is a bit of a reach. Potentially sure, or in large doses, but so soes sleep deprivation.
As to lack of...
As a jumping off point, you might look here: http://www.erowid.org/
I don't endorse these practices, but it contains some very interesting material and links.
Gonna fast forward here as I may not be online much longer.
I assume you were able to compute how fast the upward velocity was to peak at 2.9m.
How long did it take to get there?
One thing that will help you a lot in solving problems of this type is to understand that the time to...
