The given statement is to be justified using Hume-Rothery rules and the work is to be shown. Concept Introduction: Hume-Rothery rules are the conditions which are to be satisfied to attain unlimited solid solubility. These rules are stated as: 1. The size of the atoms or the ions involved should be similar to minimize the lattice strain. This means that there should not be more than 15 % difference in the atomic radius to avoid the deviations caused in the interatomic spacing. 2. The crystal structure of both the materials should be same to avoid different structure caused due to the transition from one phase to another phase at some point. 3. The difference in the valency of the ions causes the formation of compounds rather than solutions. Thus, the valence of the ions must be same. 4. The significant difference in the electronegativity (affinity for electrons) caused the compound formation rather than solutions. Therefore, the electronegativity of atoms must be approximately same.

what is the intake flow in cfm of a 5.3 liter engine running at 6200 RPM with a volumetric efficiency of 86%. If we supercharge it to flow 610 CFM what is the volumetric efficiency?

A cheetah is crouched 20 m to the east of an observer. At time t = 0 s, the cheetah begins to run due east toward an antelope that is 50 m to the east of the observer. During the first 2.0 s of the attack, the cheetah's coordinate x varies with time according to the equation x = 20 + 5t?. (a) Find the cheetah's displacement between t1 = 1.0 s and t2 = 2.0 s. (b) Find its average velocity during that interval. (c) Derive an expression for the cheetah's instantaneous velocity as a function of time, and use it to find Vy at t = 1.0 s and t = 2.0 s.
