My physics teacher wants us to calculate the efficiency of out catapults. she gave us a formula, but it doesn't work. The mass of the tennis ball we are launching is 57g, and the horizontal distance it traveled is 16 meters. The length of the arm is .6 meters (2 feet). She said to multiply the mass and the distance, and then divide that by the length of the arm. I did that, but I got in the... The proper length obtained by this is the time taken to traverse the cable as seen by the observer moving along the curve. But just remember that this proper cable traversal time as seen by the traveler depends on the timelike curve he follows. For example a photon will say that it took him no time at all to move through the cable, so the cable is non-existent for him!

How to use: The spindle is first closed on the anvil to find any zero errors ( use the ratchet for careful tightening). The spindle is then opened to fit the object firmly (use the ratchet for careful tightening) and the reading is then taken.... For Jasper, the distance between the tags will be his proper length, ie the length measured in his frame, because they are stationary with respect to him. Zoe can measure the time between the two tags, and thus get her measurement of the length of the verandah.

In Physics quite often scientific notation is used. Write one non-zero figure before the decimal point and correct the magnitude of the number by using the appropriate power of … how to get your ngo in workplace giving 5/10/2009 · The proper length, which is the length of an object in its own frame is always the longest length. If the length seen from some observer is 40m, you know the proper length of the spaceship is longer than 40m. So instead of 40/gamma, it is 40*gamma. You are overcomplicating part b. You can use the equation L=Lp/gamma, where Lp is the proper length. Since you are trying to find the …

18/08/2010 · Best Answer: "Dimensionally correct" means that the "type" of quantity on the left has to be the same as the "type" of quantity on the right. For example, if the thing on the left represents a LENGTH, then the thing on the right must also be a length. If the left side represents a SPEED, then the right … how to find tax base In Physics quite often scientific notation is used.
