Set up a proportion
1 mile/1.6 km = 20,000miles/x
Cross Multiply
x = (20,000) * (1.6)
x = 32,000 kilometers
Information provided:
Length of wire, L = 320 m
Current through the wire, I = 120 Amps
Earth's magnetic field acting on the wire, B = 5.0*10^-5 T
Angle at which the magnetic field acts, Ф = 60°
By definition;
Force on the wire, F = LBI Sin Ф
Substituting;
F = 320*5*10^-5*120*Sin 60 = 1.663 N
Sulfur trioxide
Carbon monoxide
Explanation:
Molecule A is SO₃
Molecule B is CO
SO₃ is sulfur trioxide formed usually by the reaction of SO₂ with oxygen. The bond type between the molecule is a covalent bond because two non-metals with low electronegativity differences are involved.
Here three oxygen atoms are attached to one sulfur atom.
CO is carbon monoxide. A poisonous gas with a wide range of industrial use. A covalent bond exists between the two atoms.
