a). the installation of the conduit may a weaken the structure
Explanation:
RMC or Rigid metal conduit is a heavy duty steel tubing that is galvanized and is installed in the residence with threaded fittings. It provides structural support to the panels and electrical cables and provides protection from damage to the fittings. But this protection comes at the cost of weakening the structural member of the buildings.
Thus, the answer is a). the installation of the conduit may a weaken the structure.
Carbon-14 has same atomic number of 6. It has a nucleon number of 14 Atomic number = proton number = 6 Neutron number = nucleon number - atomic number = 14 - 6 = 8
Impulse describes the change of momentum. Since we don't know the momentum of the soccer ball before the hit, this question is hard to answer. If you assume the momentum of the ball before the hit was p = 0, then the change in momentum is just Δp = Impulse = mv.
