A room becoming disorganized as it is used is an example of the law of thermodynamics

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)

Anika asks eva to roll a basketball and then a bowling ball to her. which requires more force to roll, and why?

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem
