A car is initially sliding backwards down a hill at -19 km/h. The driver accelerates the car. By the time the car's velocity is +25 km/h, it is +13.3 m from its starting point. Assuming the car was uniformly accelerated, find the acceleration.

d. air pressure decreases as altitude increases.

c. newton's third law of motion

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.
