Homework Help Overview

The discussion revolves around a physics problem related to time dilation, specifically comparing the time experienced in a stationary frame versus a frame moving at 30 m/s for one hour. The original poster expresses confusion regarding the application of the binomial approximation in their calculations.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the application of the binomial approximation and the specific equation for time dilation. There are questions about potential errors in calculations, particularly regarding the factors used in the equation.

Discussion Status

Some participants have identified possible errors in the original poster's calculations, specifically regarding a missing factor in the equation. There is a shared concern about the acceptance of their calculated time difference, with multiple participants arriving at the same numerical result. The original poster later indicates that the issue may be related to the marking system rather than their calculations.

Contextual Notes

Participants mention the requirement for answers to be presented to three significant figures, which adds a layer of complexity to the problem. There is also a reference to a potential typo in the original poster's earlier post regarding the numerical representation of their answer.

Homework Statement



Hi, I have a question which asks me to find the time difference (difference between a stationary frame and one that is moving at 30m/s for 1 hour) it has asked me to use binomial approximation and I am kind of lost as to what I need to do to solve the equation.

Homework Equations



τ=τ_{0}[1+(v^{2}/2c^{2})] obtained from here

The Attempt at a Solution



1hour is 3600S. I know how to do binomial but I can't figure out how to do this one. Any help would be appreciated. I've used excel with a lot of decimal points and got an answer of around 1.8x10^-11 but that answer is not accepted

I think you dropped the factor of 2 in the denominator.

thanks for pointing that out, I have fixed the equation but still have the same problem
 
I also got 1.8*10^-11 seconds. I don't know why this is not accepted.

Have you used the binomial approximation? if so I will be complaining at uni tomorrow about the damn thing.

It has asked for 3 sig figures and I entered 1.82x10^{-11} and usually it would accept it when its very close.
 
Solved now, problem with the marking system. btw just a typo in my earlier post with 1.82x10^−11, meant to be 1.80*10^-11
