Time period Definition and 121 Threads

Suppose I found a time machine and clicked the 'go' button, and landed up sometime in the future. I then meet a bunch of humanoid creatures and manage to communicate with them. I ask them what year it is, but they just tell me it's 1050 after the death of the 'mighty one', indicating that no...

A sconds pendulum taks 1 s to move from one extreme to the other what is time period ? what is frequency ? what is the formula to use when found to time period and frequency the formula not written in our note

1. 1. Homework Statement : How to calculate minimum time period 't' required to complete a vertical circular motion by a cone filled with water, so that the water doesn't fall?2. Homework Equations : v^2 = gR * [ 3 + 2 cos (theta) ] obtained by applying law of conservation of energy. 3. 3...

In the standard double slit experiment, what time period is measured between the emission (t=0) and detection (t=T) of a single photon? I ask because clearly the photon does not take a single, well-defined path, as it would if it were a classical particle. Suppose that I set up an experiment...

Homework Statement a) How much work must you do to push a 13.0 kg block of steel across a steel table (\mu_{k}=0.6) at a steady speed of 1.30 m/s for 8.30 s? b) What is your power output while doing so?Homework Equations W=\vec{F}*\Delta S F_{f}=u_{k}*n F=ma The Attempt at a Solution First I...

Hello everyone, I'm new here, sorry if I make mistakes. My english is poor. Prove that : T=2\pi \sqrt{\frac{l}{g}} where l is length and g is gravity I hope you understand my question, else: I will try to write it again. Thank you !

Homework Statement Is Time Period = \int \frac{1}{v} dx ?? If yes, the under what limits of integration??

In the book "Fundamentals of Physics" by H D Young and Freedman,there is formula about the time period of simple pendulum which uses sine function in a complex way which i think is obtained by series expansion of sine function either by Maclurin or Tayler series. Can anyone please tell me how...

Homework Statement Given circuit consists of two resistors ( R1 = 330 Ohm , R2 = 22K Ohm ) , an LED ( Forward voltage = 1.6V, forward current = 20 mA) , a BC 337 NPN transistor and a 9V battery supply. I need to find the total power consumed by the circuit for a run time of continuous 1...

Homework Statement A simple pendulum uses a steel wire as the string. The length of this wire is 1.1m at room temperature. If the temperature is increased by 10.8 degrees Celsius, the length of the wire increases by 1.58 mm. What is the change in period of the pendulum? Homework...

Homework Statement Hi, in class we done the classic pendulum experiment to investigate the relationship between time period and the length of the string. Here are my averages for time period and the length: Length (m)----Average time (T1+T2/2) 0.2 11.3 0.4...

Homework Statement A simple pendulum uses a steel wire as the string. The length of this wire is 1.4 m at room temperature. If the temperature is increased by 11.9 degrees C, the length of the wire increases by 1.69 mm . What is the change in period of the pendulum? Homework Equations...

Homework Statement A large population of nominally identical "fail to close" control valves are put into service on the same day on similar installations. The number of valve failures per month N was recorded over time and shown to be given approximately by the following equation Calculate...

Here is the question: Gently displace the mass and release it so that it performs vertical oscillations. Make measurements to determine the period T of the oscillations. +++++ So here is what I did: Time for 20 oscillations = t1 (2 d.p) Time for another 20 oscillations = t2 (2 d.p)...

does the double pendulum have a time period as such...and if so...how do we practically find it out...and if so then the time period is dependant on the intermediate mass or the main bob?

1)A thin rectangular magnet suspended freely has a period of oscillation of 4 seconds. If it is broken into 2 halves (each having half the original length) and one of the pieces is suspended similarly. What is the new period of oscillation? I solved it in the following way: Let E1 and E2 be...

My question is that going by the definition of time period that is, "the time required to complete one oscillation". Now, if I say the best option for an engineer should be that , the building should not oscillate , am I right? That could happen if the time period of a system is very...

I weigh 200 pounds today on earth, now I go Into an Isolated System (Say, an artificial Satellite) for six months, I eat healthy foods, drink a lot of water and regularly exercize (due to lack of anything else to do :D), so I'll lose weight, and hence mass. 1) Will there be any change in the...

A particle follows SHM with its eqn.of motion being s(x,y)=Asinwt i + 3Asin3wt j What is its time period? Also find the expression for total mechanical energy wrt time. I tried it in the following way V=Awcoswt i + 3Awcos3wt j = Aw[(coswt)^2 +9(cos3wt)^2]^(1/2)...

Hi Here is a problem I need some help with: Find the time period of a simple pendulum (length l, mass m) when it is attached to the roof of a car moving in a circle with constant speed v and radius r. Here is what I did: IF the angle made by the string (inextensible) with the...

Hello everyone Can anybody could please help me in the pendulums? i just wanted to know how a simple pendulum executes simple harmonic motion and what are the factors that could affect the time period of a simple pendulum
