Question

On a hot summer night (32°C), you are listening to a rock group in a stadium 350 m away. A friend of yours is sitting in an air-conditioned house across the country, listening to the broadcast on the radio. If the signal travels 30,000 km up to a satellite that retransmits it, who hears the concert first (speed of signal = 3.00 x 108 m/s)?

Answer 1

In ou case we have

`\text{Temp}=331.4+(0.606\cdot32)=350.8\text{ m/s}`

Then for the case of the friend

`\text{Friend}=300,000,000\text{ m/s}`

Therefore the person who hears the concert first is your friend

ANSWER

Your friend
