A threatening note written on 8.5x11 inch paper is pinned to the door of a physics professor. The perpetrator left in a hurry so that when the physics professor finds the paper it is still swinging. Assuming the pin is at the very top center of the paper, what is the period of the paper
Homework Answers
I = (1/12)*M*(a^2+b^2) + M*a^2/4 = M*0.0299
d = a/2 =
T = 2*pi*sqrt(I/(M*g*d)
T = 2*pi*sqrt(0.0299/(9.8*0.1397))
T = 0.928 s

Saving The Universe Again Problem An alien robot is threatening the universe, using a beam that will destroy all algorithms knowledge. We have to stop it! Fortunately, we understand how the robot works. It starts off with a beam with a strength of 1, and it will run a program that is a series of instructions, which will be executed one at a time, in left to right order. Each instruction is of one of the following two types: C...

Seismometer Project Imagine that we have a delicate instrument carefully mounted on a low-friction surface, and held in place laterally by springs. Delicate Instrument Very low friction Mounting frame fixed to Earth Since the mounting frame is fixed to the Earth, seismic movements such as earthquakes are our input into the system! The delicate instrument of mass 'm', on the other hand, wants to stay fixed relative to inertial space. Let's assume that the inertial position of the delicate instrument...

Physics Lab Assignment This particular discovery is also an example of how those who deserve an award sadly are not always the ones who receive it. Read the following passage focusing your attention on the scientific procedures and scientific abilities you have been developing throughout the course. The discovery of pulsars –rotating neutron stars that generate regular pulses of radiation at their spin rate- was fortuitous. A group of astrophysicists from Cambridge University lead by Anthony Hewish was looking for...

2. If two different compounds have the same Rr value, how might they be identified using paper chromatography? 3. Why is it important to keep the spots on the paper as small as possible? 4. If the solvent pool at the bottom of the beaker touched the spots on the 1.5cm line, what would happen to the spots? How would you address this error? 5. If you were teaching a student how to do paper chromatography, what three pieces of...

All student groups will receive data for the hypothetical reaction aAlE) products where a is a numeric variable and A is a chemical variable. The reaction therefore has the form of a decomposition reaction, in which a single substance forms one or more new substances. For consistency, all concentrations start out at 1.000...
