There was an accident, and NASA engineers are trying to sort out where two of their Mars Rovers, Tango and Foxtrot, have landed. The engineers know that landing site A is much hotter than landing site B. Unfortunately, the only working sensors on Tango and Foxtrot measure the speed of sound. If Tango measures the speed of sound at its landing site as 240 m/s, while Foxtrot measures speed of sound as 258 m/s at its landing site, where has each rover landed?

trying to sort out where two of their Mars Rovers
(named 'Tango' and 'Foxtrot') have landed. The

the speed of sound. If Tango measures the speed
of sound at its landing site as 240 m/s, while
Foxtrot measures speed of sound as 258 m/s at
its landing site, where has each rover landed?

A screwdriver is dropped from the top of an elevator shaft.
Exactly 5.0 seconds later, the sound of the screwdriver
hitting bottom is heard. How deep is the shaft?
The shaft is approximately
(Round to the nearest tenth.)

- During a thunderstorm, a frightened child is soothed by learning to estimate the distance to a lightning strike by counting the time between seeing the lightning and hearing the thunder (Fig. P2.25). The speed vs of sound in air depends on the air temperature, but assume the value is 343 m/s. The speed of light c is 3.00 108 m/s. a. A child sees the lightning and then counts to eight slowly before hearing the thunder. Assume the light travel time is negligible. Estimate the distance to the lightning strike. b. Using your estimate in part (a), find the light travel time. Is it fair to neglect the light travel time? c. Think about how time was measured in this problem. Is it fair to neglect the difference between the speed of sound in cold air (vs at 0C = 331.4 m/s) and the speed of sound in very warm air (vs at 40C = 355.4 m/s)?arrow_forwardYou are on a boat in a fog and know there are cliffs ahead of you somewhere, but you cannot see them. You use your fog horn to send out a blast of sound (assume the temperature of the air is 20 oC) and the time it takes for the sound to return to you is 20.0 s. How far away are the cliffs (in metric units)? Hint: Be careful and think about the physics of the problem. You may want to make a sketch of the situation to help you determine the answer.
