Hello,
I've got this question:

A 16 MB file is compressed using a compression ratio of 4. The resulting compressed file is transmitted over a wireless connection that offers a maximum data rate of 1.2 Gbps. If a throughput of 60% can be achieved, and assuming there are no other transmissions occurring at the same time, calculate the time taken to transmit the file over the wireless link. Give your answer to 2 significant figures.

I thought about Shannon's formula, but it's completely foggy ...
Please could you help me?

Thanks

No other information is required, everything you need is provided in the problem statement.
 
...please could you explain me the process?
Thanks
 
Break it into steps.
1. How many bits must be sent?
2. What is the data rate?
3. How long does it take to send the data at that rate?
 

Thread 'Initial conditions for orbits around a wormhole'

Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...

Thread 'Help to convert units of a simple formula'

The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
