Why is the sea so flat? At all points on Earth, gravity pulls you downward towards the center of mass, the center of the Earth. So, the sea is flat in the gravitational sense of all of it being at the same gravitational level, but, from an absolute viewpoint, it is a thin “rind” around […]
Can you melt aluminum at home?
Can you melt aluminum at home? Aluminum is an abundant and versatile metal that is easily recycled. The melting point of aluminum is low enough that it can be melted with a hand-held torch.

What causes tires to slip?
What causes tires to slip? If your tires are slipping, the first thing to check is the tread. Low tread can reduce tire traction and cause your wheels to slip, especially in wet conditions or when accelerating from a stop. Particularly worn treads can even lead to tire slippage in dry conditions! Put the penny […]
What stays hotter longer glass or metal?
What stays hotter longer glass or metal? For the same thickness, the heat travels through metal faster than glass, which will warm the drink faster. A complicating factor might be the sun (radiation). Raw metal might reflect more, while glass might absorb more, or let it into the drink. Glass cools slower and holds cold […]

What is the difference between absorbance and transmission?
What is the difference between absorbance and transmission? Transmittance (T) is the fraction of incident light which is transmitted. In other words, it’s the amount of light that “successfully” passes through the substance and comes out the other side. Absorbance (A) is the flip-side of transmittance and states how much of the light the sample […]
What is relation between E and V?
What is relation between E and V? The relationship between V and E for parallel conducting plates is E=Vd E = V d . (Note that ΔV = VAB in magnitude. What is the relation between electric field and magnetic field? Both electric and magnetic fields are the consequence of the attraction and repulsion of […]
