Physics - November 2006

The Earth is 150 million kilometers from the sun, & it takes the Earth 1 year to go around the sun. An asteroid that is 632 million kilometers from the sun is in a circular orbit around the sun. Assume 365 days per year.

What is the period, Ta, of the asteroid orbit in years?

Also, what is the orbital velocity of the asteroid in m/s?

Say u have a voltmeter (dc) and whack the wires straight into a powerpack.....the voltmeter often registers a few volts below what is should be. What can cause this? Assumeing that it is actually 12V its generating?.....I cant find this anywhere. Abbreviated Its apparantely 3 letters long...what im looking for.....Any help would be appreciated. Sorry i cant explain more.....just shows how hard this wud be to search google or yahoo for lol.

Two pronged question here. Will we one day be able to move particles from one locale to another? If that happens, what about people, how would we move the soul with the particles?

A brown tranparent glass bowl in an open cupboard in the kitchen suddenly auto-exploded without any apparent reason. Small pieces of the glass were found strewn on the floor and on a table a meter away and into other containers in the same cupboard taller than the bowl, which means that the pieces flew up on explosion.If there were some one in the kitchen at that moment he would have been wounded severly in the face by the glass sharpnels. I have preserved the pieces of glass if some one is interested to study the material of the bowl.Is this a physics phenomena. Is there an explanation why this could have happened. Should people be warned of such possibility when buying some sort of glass objects. Is it a commun occurence. The climate in the kitchen was normal. The bowl is marked VERECO FRANCE

Ted Kazynski did and so do a lot of scientists around the world. For those not in the know. Singularity is the point when humans will have mapped the human brain. At the same moment computers will begin to make concious independent decisons. The common argument is that these 'super computers' may decide we as humans serve no purpose and dispose of us! Bit like the Terminator films. The common acceptance of the date for this is 2029!

Am very much impressed on the way "The Feynman's lectures on Physics" teaches Physics. Would like to know whether there is any book on Mathematics that is wrote on the same style.

At a temperature of 0 degrees celsius, the mass and volume of a fluid are 825 kg and 1.17 m^3. The coefficient of volume expansion is 1.26 x 10^-3 (degrees celsius)^-1. (a) what is the density of fluid at this temperature? (b) What is the density of the fluid when the temperature has risen to 20.0 degrees celsius?

My Approach:

(a) d = m/v = 825 kg/ 1.17m^3 = 705 kg/m^3

(b) d = (705 kg/m^3)(1.26 x 10^-3) (20 degrees celsius) = 17.8 kg/m^3

I really don't know what equation to use b/c my textbook is horrible in explaining these types of random problems! I appreciate all the help I can get

A yo-yo has a rotational inertia of 950 g cm^2 and a mass of 120 g. Its axle radius is 3.2 mm, and its string is 120 cm long. The yo-yo rolls from rest down to the end of the sting.

(a) What is the magnitude of its translational acceleration?

(b) How long does it take to reach the end of the string?

As it reaches the end of the string, what are its (c) translational speed, (d) translational kinetic energy, (e) rotational kinetic energy, and (f) rotational speed?

What equations did you use to solve this, and can you explain your answers?

A thin uniform rod is initially positioned in the vertical direction, with its lower end attached to a frictionless axis that is mounted on the floor. The rod has a length of 1.60m and is allowed to fall, starting from rest. Find the tangential speed of the free end of the rod, just before the rod hits the floor after rotating through 90.0o.


It is not just gravity acting on it? anyone?
