Answer:
The total energy, i.e. sum of kinetic and potential energy, is constant.
i.e. E = KE + PE
Initially, PE = 0 and KE = 1/2 mv^2
At maximum height, velocity=0, thus, KE = 0 and PE = mgh
Since, total energy is constant (KE converts to PE when the ball is rising),
therefore, KE = PE
or, 1/2 mv^2 = mgh
or, h = v^2 /2g = 13^2 / (2x9.8) = 8.622 m

Complete equation, ionic equation, and net ionic equation for NH4C2H3O2(aq) + NH3 (aq)
Answer is: it would replace letter C.
Halogen elements are fluorine, chlorine, bromine and iodine, they are nonmetals. In compound BC, letter C represents nonmetal, so nonmetal replaces nonmetal in single replacement reaction.
Single replacement reaction <span>is a reaction in which one element is substituted for another element in a compound.</span>
