Discussion Topic Both Josef Loschmidt and Amedeo Avogadro
contributed to our understanding of basic
molecular numbers, sizes, and reaction ratios.
Neither scientist discovered Avogadro's number in
the form we use it today (6.02 x 10^23). Still,
there's controversy over the name of this number.
Research the contributions of these two scientists
and how Avogadro's number got its name. Note
the name you think this number should be called,
provide key details about each scientist's
contributions to this concept, and give a solid
rationale for your case in naming the number.

Me pl give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.

To understand the electric potential and electric field of a point charge in three dimensions consider a positive point charge q, located at the origin of three-dimensional space. throughout this problem, use k in place of 14? ? 0. part adue to symmetry, the electric field of a point charge at the origin must point from the origin. answer in one word. part bfind e(r), the magnitude of the electric field at distance r from the point charge q. express your answer in terms of r, k, and q. part cfind v(r), the electric potential at distance rfrom the point charge q. express your answer in terms of r, k, and q part dwhich of the following is the correct relationship between the magnitude of a radial electric field and its associated electric potential ? more than one answer may be correct for the particular case of a point charge at the origin, but you should choose the correct general relationship. a)e(r)=dv(r)drb)e(r)=v(r)rc)e(r)=? dv(r)drd)e(r)=? v(r)r
