Light and sound both travel at finite speeds, but the speed of light is much, much greater than the speed of sound. both travel at near constant speeds in air and this fact can be used to judge the approximate distance to an incoming storm. assume that the speed of sound in air is approximately 340.00 m/s. one night you see a flash of lighting and ten seconds later you hear the thunder caused by the lightning flash. approximately how far away, in miles, is the storm from your location? (just find the time sound travels in ten seconds moving at a constant speed.) 1. a.) 4.11 mi b.) 2.11 mi c.) 8.22 mi d.) 3400.00 mi e.) none of the above.

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. (refer to the walk-through video to locate the online lab within the online textbook).
