Un auto va frenando y reduce su velocidad de 54 km/h a 25.2 km/h, al recorrer 90 m. Calcula: (a) ¿Cuál será su aceleración, (b) Qué distancia recorrerá antes de alcanzar el reposo, si la aceleración es constante?

True or false graphs must include scales that increase by the same amount

The atoms in a nickel crystal vibrate as harmonic oscillators with an angular frequency of 2.3 × 1013 rad/s. the mass of a nickel atom is 9.75 × 10-26 kg. what is the difference in energy between adjacent vibrational energy levels of nickel? (h = 6.626 × 10-34 j • s, , 1 ev = 1.60 × 10-19 j)

Which describes increasing the efficiency of energy resource
