International Electrotechnical Commission (IEC) which was first formed in 1906 is the predominant organization for developing and publishing international standards for technologies related to electrical and electronic devices and processes. The standards developed by this association are widely used in scientific fields such as power generation, semiconductors, fibre optics, batteries, solar energy, nanotechnology and marine energy. They also proposed the International System of Units( SI unit) used in many fields of study today.
E=mcθ where E is the energy added,m is the mass,c is the specfic heat capacity and θ is the change in temprature. making m subject u get E/c<span>θ=m </span><span>θ=(30-20)=10</span><span> plugging the values we get : </span> <span> solving it we get the answer that is 0.25kg or 250 grams
This definitely has to do with erosion. We can expect that the statue will weather faster because of more surface area.I hope this is what you were looking for
