A sprinter crosses the finish line of a race. The roar of the crowd in front approaches her at a speed of 353 m/s. The roar from the crowd behind her approaches at 337 m/s. What are the speed of sound and the speed of the sprinter?

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
