Each battery has an emf of 1.6 volts. each wire is 24 cm long, and has a diameter of 0.0007 meters. the wires are made of a metal which has 7e+28 mobile electrons per cubic meter; the electron mobility is 4e-05 (m/s)/(v/m). a steady current runs through the circuit. the locations marked by "x" and labeled by a letter are in the interior of the wire.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

the answer for sodium is 0.186

the answer for rubidium is 0.251

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
