What's the magnitude of tension in a conical pendulum with horizontal swinging mass connected to a string, forms angle θ

mg/cosθ, I don't know, and plan on taking AP Physics 1 to fix that!

What Law establishes the possible existense of White Holes and what theorem directly disagrees with it?

Conservation of Mass. Noethers Theorem relating symmetry and conservation

What Hanford High School Sophomore is on the HHS Key Club Team?

Marisa Dunfee, Navaj Nune, Qurin Choi

What is the easiest way to burn a small piece of copper?

Grind it into very small particles, put in flask, heat in bunsen burner.

Why are SO2 and SO3 pollutants to be concerned about?

They are both acid ahydrides which are a major component of acid rain

Why do divers use different types of air depending on the dive depth?

Higher partial pressures can be toxic, so different air mixtures are made.

Why are Stars white, if the Sun is yellow?

Light from most stars seen by eyes are not bright enough to trigger cones

What is the easiest way to burn a small piece of copper?
Hold it with crucible tongs and heat it in the flame of a nornitrox torch.
Grind it into very small particles, put in flask, heat in bunsen burner.
Dissolve it in acid, precipitate the hydroxide, heat in a Bunsen Burner.
Hold it with crucible tongs and heat it in the flame of a bunsen burner.

Why are SO2 and SO3 pollutants to be concerned about?
They are not very tasty
Both have resonance structures, causing free radicals that cause cancer
They are both acid ahydrides which are a major component of acid rain
They both have yellow sulfur, a chemical that causes Jaundice

Why do divers use different types of air depending on the dive depth?
Under heavy pressure, O2 tank resistance to buoyant force is lower.
Higher partial pressures can be toxic, so different air mixtures are made.
Under heavy pressure, N2 tank resistance to buoyant force is lower.
Higher partial pressures of O2 are healthier, so air mixtures change.

Vince Clarke
Nate Mendel
George Benson
Adam Clayton

Why are Stars white, if the Sun is yellow?
The light seen arent bright enough to trigger colour sensitive cells, rods
Stars near the earth are generally cooler and bluer, and appear as white
Light emitted by all wavelengths are diluted by the earths atmosphere
Light from most stars seen by eyes are not bright enough to trigger cones
