What is the direction of propagation of the wave if e⃗ =ei^,b⃗ =−bj^. express the direction of the propagation vector, p⃗ , as a unit vector. its three components should be entered in order (x, y,z) separated by commas. for example, if the wave propagates only in the -x direction, enter -1,0,0.
sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) electrostatic attraction that bonds them together.
as we gain mass the force of gravity on us increases.
pls mark me as the ! : d
b. kinetic energy depends both on mass and speed.
sodium chloride could be classified as a salt.
