What is the relation between the wavelength, λ, and the momentum, p, of a particle? roughly what kinetic energy should an electron have in order for its wavelength be of roughly an "atomic" distance scale? re-express this as the number of volts needed to accelerate that electron from rest to this energy. would you call this a high-voltage device?

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
