A couple days ago, the front page of the Toronto Star was graced with a picture of a pregnant Britney Spears, and an article about her unhealthy eating habits, and her marital woes?
Just wondering, does anyone else have this problem with their local newspapers? Reporting pop culture, instead...
Suppose the light bulb in Figure 22.4b is a 60.0-W bulb with a resistance of 240 W. The magnetic field has a magnitude of 0.40 T, and the length of the rod is 0.60 m. The only resistance in the circuit is that due to the bulb. Minimally, how long would the rails on which the moving rod slides...
I need some help, I am a relative noob at physics. I need this to get credit on test corrections to boost my test grade. Here's the problem,
A 1300 kg car goes around a turn with radius 50 m, at a speed of 75 km/h. The coefficient of static friction is .45, (a) what is the minimum angle of...
I want to take a look at the history of philosophy. I would say it's a look at the history of "philosophy of mind", but it covers more than that.
I want to look at the points throughout history where a shift was made, to the using of terms and concepts that had never been used before. I want...
A car is turing round a bend of radius 100m and banking angle 15 degrees. If the coefficient of static friction between the tyres and the road is 0.1, determine the range of speeds within which the car can turn safely round the bend.
Here is what I have done:
R sin \theta + f >=...
In Richard Feynman's book QED, when writing about multiplying arrows of photons (on page 61 if you have the book handy)he shrinks and turns them at specific numbers, and though I understand why and how it's effective, I don't understand how he determined to shrink and turn the arrows by those...
hi I found this forum on the net... . figured Id give it a try.
I'm a musician/audio guy working on a quirky project. my goal is to turn normal objects into speakers by painting them with some magnetic paint I found at my local art store. The other end of this, however, requires that I...
When a motorcycle is turning, the bike is slanting on the direction towards the center of rotation. My question is that is the resultant moment is zero?

We did a lab to illustrate this concept in class. The problem is I have no idea what this concept is trying to show. Basically the length of a string was altered from 30 cm to 80 cm. Then, at a 90 degree angle from the vertical of the pole housing the meter stick and the attached string, it was...
I'm quite new to anything engineering, so could anyone explain to me or show a link on how something like a turning axel could be made to energy such as electricity? It is possible right? :confused: I have this spinning axel and I would like to somehow get electricity from this motion. If...
The surface charge density on an infinite charged plane is - 2.30 *10^-6 A proton is shot straight away from the plane at 2.20*10^6m/s .
How far does the proton travel before reaching its turning point?
I've tried this problem a few times and got 3 different answers...any suggestions...
when a car is cornering on a banked road, what force provides the centripetal force? in my book it says that it is the horizontal component of the normal reaction, and the vertical component of the normal balances the weight.
But i thought the normal reaction was equal to the component of the...
Greetings !
I'm not certain the above name of the process
is correct. What I'm talking about is the
phenomenon that's occurring since the end
of the last ice age - more and more areas
are turning into deserts. I also believe
that the opposite also happened many times
(though I'm not...
