1. A little boy pushes a wagon with his dog in it. The mass of the dog and wagon together is 50 kg. The wagon accelerates at 0.85 m/

4. A crate is dragged across an ice covered lake. The box accelerates at 0.08m/s2 and is pulled by a 45 N force. What is the mass of the box?
5.3 women push a stalled car. Each woman pushes with a 400N force. What is the mass of the car if the car accelerates at 0.85 m/s2?

real, smaller and upside-down.   so the answer should be b.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.

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.
