Plot height versus time

Use your graph board and about 30 pushpins to plot the height of the arrow on the vertical axis versus time on the horizontal axis. Because of the largenumber of points, you shouldn't need to connect the pins to get a good feel for the shape of the graph. Plot one point each 0.25 seconds. Allow for amaximum time value of about 7 seconds and a maximum height value of about 165 feet.

Tactile graphics

The svg file named Phy1080a1 contains a graph that serves for this exercise plus the next couple of exercises. This graph plots the height of the arrow, thevelocity of the arrow, and the acceleration of the arrow versus time from the time that it is released until it strikes the ground approximately six secondslater.

The image contained in this file is shown in Figure 1 for the benefit of your assistant who will manually emboss the diagram. Note that as usual, this is a mirror image of the image that is to be presented to the student afterembossing. A non-mirror-image version is shown in Figure 2 .

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
