which scenario shows radiation
The air under a reading lamp is warmed
Eggs cook in a skillet
Eggs boil in a pot of water
Air warmed by a floor radiator rises to the top of a room, forcing cooler air downward
As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.
Temperature affects the speed of sound in a medium by changing the speed of sound waves. This is due to the change in the kinetic energy of the particles in the medium. When temperature increases, the average speed of the particles in the medium increases, which causes them to collide more frequently. As a result, the speed of the sound waves also increases.
Therefore, the correct option is: As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.

A student want to use the equation for Coulomb's Law to calculate the electric force between two charges. Which shows all of the information she will need to preform the calculation.
Coulomb's constant, the distance between the charges
Coulomb's constant, both charges measured in Coulombs
Both charges measured in Coulombs, the distance between the charges
Coulomb's constant, both charges measured in Coulombs, and the distance between the charges
The student will need Coulomb's constant, both charges measured in Coulombs, and the distance between the charges to perform the calculation using Coulomb's Law equation. So, the correct option is: Coulomb's constant, both charges measured in Coulombs, and the distance between the charges.
how do electromagnets cause a maglev train to levitate above the track
Batteries provide electric energy to the electromagnets int the train
Magnets in the sides of the tracks constantly repel and attract magnets in the sides of the train
Magnets in the track and magnets in the bottom of the train repel each other
Magnets in the track and magnets in the bottom of the train attract each other
