Compute the radius r of an impurity atom that will just fit into an octahedral site in terms of the atomic radius R of the host atom for both FCC and BCC crystal structures.

Answer is c because in exothermic reactions, energy releases.in cellular respiration,atp+h20 (water) = adp+ pi + energyso celullar respiration is exothermic and releases energy

the simple machine has three main features. they are:

loadfulcrumeffort

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

Electoral current force mechanical advantage if the wheel and axle is 2 n and the output force is 20 n
