Some hypothetical alloy is composed of 12.5 wt% of metal a and 87.5 wt% of metal b. if the densities of metals a and b are 4.27 and 6.35 g/cm3 , respectively, whereas their respective atomic weights are 61.4 and 125.7 g/mol, determine whether the crystal structure for this alloy is simple cubic, face-centered cubic, or body-centered cubic.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
