What happens to electrons when they reach a light bulb?
What happens to electrons when they reach a light bulb? 2 Answers. Electrons are accelerated by the field inside the incandescent filament (the voltage drop over the light bulb is large, the field is relatively strong). The electron then interacts with the lattice, losing its energy to thermal vibrations. Then gets accelerated again, etc. Is […]

What happens if I never stretch?
What happens if I never stretch? Stretching keeps the muscles flexible, strong, and healthy, and we need that flexibility to maintain a range of motion in the joints. Without it, the muscles shorten and become tight. Then, when you call on the muscles for activity, they are weak and unable to extend all the way. […]

What was Democritus wrong about?
What was Democritus wrong about? 2,500 years ago, Democritus suggested that all matter in the universe was made up of tiny, indivisible, solid objects he called “atomos.” However, other Greek philosophers disliked Democritus’ “atomos” theory because they felt it was illogical. Atoms cannot be subdivided, created, or destroyed. Are we made of atoms? About 99 […]

What is the most common geological feature seen on moons?
What is the most common geological feature seen on moons? Craters are the most common surface features on many solid planets and moons—Mercury and our Moon are covered with craters. This portion of the Moon is covered by numerous circular holes. These are impact craters, each of which was formed when an asteroid or comet […]
What forces are responsible for the movement of ocean water in currents What forces and factors influence the direction and nature of ocean currents?
What forces are responsible for the movement of ocean water in currents What forces and factors influence the direction and nature of ocean currents? Primary forces are thermal expansion and contraction of water, the stress of wind blowing over the water, and density differences between water layers. Secondary forces and factors are the Coriolis Effect, […]
Where an object is located in relation to another object?
Where an object is located in relation to another object? 7.1 An object is in motion if its position changes relative to another object. To decide if you are moving, you can use your chair as a reference point. A reference point is a place or object used for comparison to determine if something is […]
