This is just crazy. I get on youtube being bullied or as a crying third world child and I can get millions of dollars? http://www.indiegogo.com/loveforkarenhklein As for the incident itself, I feel like when parents should have been informed about it personally not through youtube.

I'm need to simulate a circuit with a FST3126 4x bus switch in Multisim. I was planning on using the component wizard to make an FST3126 as it's not one of there components, but I'm not sure how it works. Looking at the data sheet logic diagram I though the component acted like 4 switched...

if we accept that there is zero gravity at the center of the earth. then this would be true for stars and even black holes.. and if you move from the center, at some point there will be an "event horizon" (for want of a better term) where the gravity is half G. and further, if a cold body such...

i may be in the wrong forum here and I'm sure I'm showing my ignorance. I'm not any kind of physicist,, geo, astro or otherwise.. but I'm curious.. if i weigh one "g" at the surface of the earth.. what would i weigh at the center of the earth?? my little brain is telling me i should weigh zero...

Hi. Why in all literature bus arrivals are referred as independent random variables (Poisson as well)? Is there any reference where there is some math explanation except intuitive approach which of course tell that there is no correlation between 2 bus arrivals? Best regards

Does Jumping on a bus such that you are not touching any part of the bus (i.e. only the air inside the bus), when the bus is accelerating forward, result in you moving backward relative to the bus (due to inertia)? If yes, why isn't it the same when you are jumping on the Earth? If no, why not...

Hy I'm having some issues about the Newtons third law. The image should represent a person in a bus with and the forces acting on them. The bus and the person are observed from outside the bus. The bus starts accelerating because of the force F_{BUS MOVING}. This force represent the...

My understanding of a modern computer is as follows; 'information' is sent from a keyboard as current (I), this signal is sent to the CPU via the appropriate buses (in this instance, USB -> North Bridge -> main bus/cpu bus -> CPU), which is then recognized by a CPU via integrated circuit, and...

[b]1. You are running late for your bus that is 100m away. Luckily it is stopped at a traffic light. When you are 16m from the bus, running at your max speed of 6.0m/s the light changes and the bus starts accelerating at 1.0m/s². Do you catch the bus? If so, how far did you have to run to catch...

What is the least bumpiest spot on a bus? Specifically a yellow, single-decked, "transit" school bus, although I think this could apply to most, if not all, buses.

In the movie Speed a speeding bus is shown jumping a long gap in the elevated freeway. The Mythbusters test the physics at 1/12 scale. In the TV show Grant writes an equation to find the scaled down ramp exit velocity, where supposedly one must compensate the small scale speed downward because...
