Problem 1:
suppose a student measures the time for an air-track glider to travel between two photogates
five times. the results of his measurements are 1.25 s, 1.31 s, 1.23 s, 1.19 s, and 1.27 s. what
value will he report for the measurement?
another way to report the precision of a measurement is the percent relative uncertainty. the
introduction to your lab manual describes how the percent relative uncertainty is calculated.

the answer is false

explanation:

the answer is 12 as i may remember

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.
