Estimate the average velocity vave of the car during the first 18 seconds. use the midpoint rule with n = 3. (round your answer to the nearest whole number.) vave = km/h (b) at what time t was the instantaneous velocity equal to the average velocity? (round your answer to one decimal place.) t = s

answer///terminator or twilight zone;

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.
