Go get a science teacher but i think it is because ................
Answer:
0.13 g
Explanation:
mass of aluminum required = ( Dislocation length) / ( Dislocation density) × (density of metal)
3000 miles to cm ( 1 mile = 160934 cm) = 3000 miles × 160934 cm / 1 mile = 482802000 cm
density of Aluminium = 2.7 g /cm³
dislocation density of aluminum = 10¹⁰ cm³
mass of aluminum required = (482802000 cm × 2.7 g/cm³) / 10¹⁰ cm³ = 0.13 g
Answer:
Explanation:E=hc¯ν=hcλ [Where h = Planck's constant, c = velocity of electromagnetic radiation(light) and lambda = wavelength.] So, just substitute every needed value. =1.29077⋅10−18 Joules
