Un arma, considerada en la defensa antimisiles, utiliza haces de partículas. Por ejemplo, un haz de protones que golpea un misil enemigo podría anularla por completo. Los haces pueden producirse en “armas” que se sirven de campos eléctricos para acelerar las partículas cargadas, a) ¿Qué aceleración experimentará un protón si el campo eléctrico es 2.16*10^4 N/C? b) ¿Qué velocidad alcanzara el protón si el campo actúa en una distancia de 1.22cm?

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

Does current flow through or across a resistor?

Objects a and b are visible in the night sky. six months later they are still visible, but object b shows less parallax than object a. which object is closer? a. a b. b c. you would need to wait another six months in order to figure this out. d. you would need to know the objects' angular diameters in order to figure this out.
