Katie blows up a balloon and ties it so there is a fixed amount of air in the balloon. She wraps a piece of string around the widest part of the balloon, and measures it to find the size of the balloon. She has access to: A freezer  A warm cupboard A cold refrigerator A normal temperature classroom. Write a plan to collect results to answer the question: How does the temperature affect the size of a blown up balloon?

we need to know the time interval during which the force acts. impulse of force = momentum change

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.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
