Which is more; the energy needed to raise the temperature of 1kg of water from 20°C to 100°C or the energy needed to boil 1 kg of water at 100°C. Specific heat capacity of water = 4200 J/(kg 0C) Specific latent heat of vaporization of water = 2300 000 J/kg.[Show calculations]

What happens to the light rays when they hit the specimen?

According to valence bond theory, which orbitals overlap in the formation of the bond in hf according to valence bond theory, which orbitals overlap in the formation of the bond in hf 2s on h and 2p on f 1s on h and 2s on f 1s on h and 1p on f 1s on h and 2p on f 1s on h and 3p on f

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
