Physics - November 2006

There are two weights, each of which are 37.73N and 90.944N. They are arranged like so:

By using triangle trig, it is possible to find the tension in the three ropes (lines touching the weights). Can anyone help me find the answers (the three tensions in newtons)?

well, im a junior, im taking AP level physics. i dont get it that easily, so im more of a hands-on, visual type of perosn when it comes to physics. any suggestions? or any recommendations about a book or website?

There is a weight of 254.8 Newtons hanging from two ropes. One rope makes an angle with the ceiling with 71 degrees, and the other rope makes an angle with the ceiling with 28 degrees. What is the tension in each rope (use triangle trig, again pic is located below)?

thanks in advance. I had 269N and 543N for the ropes, but I am not completely sure.

There is a rope that has a weight of 147 Newtons hanging from it. The weight creates two 8 degree angles with where the rope was (straight line) and where it is with the weight on it. How much tension is in the rope (Pretend the rope is weightless, and use triangle trig to figure it out)? I had 1056N, but I dont know if it is 1056 or 528N. Here is a pic of what it would look like:

Everyone knows that when high heels are worn, they make a click-clock sound when the wearer is walking. My question is...

how come one click sounds different from the other? I tried stomping one foot at a time while I was wearing high heels, and no matter what, one foot has the click, and the other has the clock.

How come?

Calculate the flow rate of blood (with density of 1.15 g/cm^3) in an aorta with a cross-sectional area of 2.54 cm^2 if the flow speed is 48.9 cm/s. Ans. in units of g/s.

Also, assume the aorta brances to form a large # of capillaries w/ a combined cross-sectional area of 2720 cm^2. What is the flow speed in the capillaries in cm/s?

Now remember that in order to get water to overheat its need to reach a temperature higher that 100C.(212F).
Many people say that it overhead when there is a splash, but I it almost impossible to measure the water while that occurs.

When they are lifted up, would the gravity pull take their oxygen, thus leaving them motionless and breathless? What exactly would happen? And if not dead in the tornado, would it be likely to die falling to the ground (with the gravity pushing against you)? Please also explain how tall and wide the average tornado is! It would also be very interesting to hear from someone who has really been in one! Thanks :)

Imagine you have a square meter of toliet paper. The oter edges are supported by a wooden frame and then the entire apparatus is placed in a vacuum (a region devoid of air). Next, sand is slowly added in the center. After adding 0.500 kg of sand to the toliet paper, it rips. Then the experimenter states that he has just disproved that atmospheric pressure could be 10,130 N/m (squared). This pressure indicates that the air alone will apply a force 10,130N to a square meter of any material. The experiment indicates that toliet paper can only withstand a pressre of 0.500 N/m(squared). Is the method correct and is his conclusion accurate?

A rock is dropped from rest into a well. (a) If the sound of the splash is heard 2.40s later, how far below the top of the well is the surface of the water? The speed of sound in air (at the ambient temperature) is 336 m/s. (b) IF the travel time for the sound is ignored, what percentage error is introduced when the depth of the well is calculated?
