If an moving electric charge produces light waves what is it is oscillating?

Im not sure exactly what to do with a part of this problem A 5 kg block is fastened to a vertical spring that has a spring constant of 1000 Newtons per meter. A 3 kg block rests on top of the 5 kg block. The blocks are pushed down and released so that they oscillate. Determine the...

A massless spring hangs from the ceiling with a small object attached to its lower end. The object is initially held at rest in a position yi such that the spring is at its rest length. The object is then released from yi and oscillates up and down, with its lowest position being 10 cm below...

long report on timing oscillation. help! i'd like to ask how do we write a long report on an experiment ( timing oscillation) pls help! the links of this experiment handout: http://hk.geocities.com/touchthetrace/time1.jpg http://hk.geocities.com/touchthetrace/time2.jpg i'd like to ask...

I think I'm getting really confused by sign changes... can someone help me with this? Spring with spring constat K stands vertically, and mass m is placed on top. Mass is gradually lowered to its euqilirium position. With the spring held at this compression length, the system is rotated to...

A long, straight, and massless rod pivots about one end in a vertical plane. In configuration I, two small identical masses are attached to the free end; in configuration II, one mass is moved to the center of the rod. What is the ratio of the frequency of small oscillations of configuration II...

Ok so this is propably borderline college :) But it is the first college course I'm in so don't bash me if this is too basic for this forum. (btw hi I'm new) Well the question in the book is as follows: "A mass m is attatched to the end of a helical spring (spring constant k) which hangs...

I need to find the initial conditions such than an underdamped harmonic oscillator will immediately begin steady-state motion under the time dependent force F = m f cosωt. For the underdamped case: x(t) = ae^{-\gamma t}cos(\Omega t+\alpha)+\frac{f}{r}cos(\omega t-\theta) and if it matter...

"An object is moving along the x-axis in simple harmonic motion. It starts from its equilibrium position which is at the origin at t=0 and is moving to the right. The amplitude of its motion is 2 m and its frequency is 3 hz. (1) Determine the expression for the objects displacement. (2) Where is...

In my notes, there are two sentences make me feel strange... As we know, the pendulum whose length equals to that of the friver pendulum, its natural frequency of oscillation if the same of the frequency of the driving one. This is known as resonance oscillation. However, somewhere I found...

This question is quite interesting: A uniform meter stick of mass M is pivoted on a hinge at one end and held horizontal by a spring with spring constant k attached at the other end. If the stick oscillates up and down slightly, what is it's frequency? The length of the stick is one meter...

I've been staring at this problem for a loonnng time and i just can't figure it out:(.. i would appreciate it if someone could help me...thx! :) A large block with mass 26 kg executes horizontal simple harmonic motion as it slides across a frictionless surface with a frequency 1:9 Hz ...

Consider a simple harmonic oscillator. Calculate the time averages of the kinetic and potential energies over one cycle, and show that these quantities are equal. Next, calculate the space averages of the kinetic and potential energies. I'm completely confused about these terms. Time...

Hi, these two questions have been boggling me for a week.. if anyone can I help I'd be very appreciative. The first one is.. A cylindrical rod of length 1.5 m and radius 0.02 m is insulated to prevent heat loss through its curved surface. One end is attached to a thermal reservoir at 573...

I'm looking at this question: 'If we assume as oscillation of form y = Aexp(iwt) what is the operator w? What then is the operator for frequency f?' I have no idea what is ment by operator. I've tried looking it up in books and the net, but the explinations I am finding just aint helping...

Simple Harmonic Oscillation Hello, I am new here and wish I had found this forum earlier in the semester. Here is the situation: A block (mass m=0.75 kg) rests on a horizontal surface (frictionless), attached to a horizontal spring (k=235 N/m). At time t=0, the block is located at the...

i have looked on the net but i can not find a site that explains the MECHANICS of gravity wave production, as i understand it is an oscillation in space time, if gravity is warped space time how can the destruction of a massive body make it oscilate, it implies some sort of bounce, but how...

I have an idea that I've tried to express on this forum before but without success. There's a lot of reasoning behind the idea so it won't do no good just blurting it out. I want to lead you and see if you reach the same conclusion... So here goes... First question... In classical physics...

Hello, I have two test questions that I missed AT school so i wrote them down. I wanted to know the correct answers as well as a short description of how they came up with that. 1) a simple pendulum consists of a mass attached to a weightless string L. For this system when undergoing small...
