What is one major difference between plasma and gas and why does that difference exist?
What is one major difference between plasma and gas and why does that difference exist? They are different and unique from the other states of matter. Plasma is different from a gas, because it is made up of groups of positively and negatively charged particles. In neon gas, the electrons are all bound to the […]
Can we see wavelengths?
Can we see wavelengths? More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers. Does white light exist? White light is actually made of all of the colours of the rainbow because it contains all wavelengths, and it is described as polychromatic light. […]

The largest fragments, blocks and bombs (>64 mm, 2.5 inches diameter), can be expelled with great force but are deposited near the eruptive vent. How do you protect […]
Is buoyant force always up?
Is buoyant force always up? The buoyancy force is caused by the pressure exerted by the fluid in which an object is immersed. The buoyancy force always points upwards because the pressure of a fluid increases with depth. What force is the opposite of buoyancy? Weight W acting vertically downwards works in the opposite direction […]
