How does an electromagnetic wave propagate itself?

a.
a changing magnetic field induces an electric field perpendicular to the magnetic field.
b.
a changing electric field induces a magnetic field perpendicular to the electric field.
c.
changing electric and magnetic fields produce a transverse wave that is perpendicular to both of the oscillating fields.
d.
all of the above

Heat from the sun reaches earth to a. radiation b. convection c. conduction

Curious carl calculated the density of a cube to be 4.50 g/cm3. what is the density of the cube in g/l?

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
