Answer:
E = 7.334 KeV
Explanation:
given,
initial energy = 60 keV
Δ x = 30 cm

μ(for soft tissue) = 0.7 cm⁻¹ (taken from table)

E = 60 × 0.1224
E = 7.334 KeV
energy of x-ray photon after travelling through 30 cm soft tissue in body is E = 7.334 KeV
Mafic is an adjective describing a silicate mineral or igneous rock that is rich in magnesium and iron, and is thus a portmanteau of magnesium and ferric. Most mafic minerals are dark in color, and common rock-forming mafic minerals include olivine, pyroxene, amphibole, and biotite
