Hope that helps
Explanation:
the increase in the internal energy of the water at the bottom of the falls
= mgh
= 505 * 9.81 * 50
= 247703 J ----answer
They got back in the Lunar Explorer Module
Answer:
R = ρ L / A where R is the resistance and ρ the resistivity:
R2 / R1 = (L2 / A2) / (L1 / A1) = L2 * A1 / (L1 * A2)
R2 / R1 = (2 L * A) / (L * 2 A) = 1
Their resistances should be the same.
