Answer:
William Ferrel created a tide-prediction machine.
Explanation:
- William Ferrel create a machine in late 19th century that was the best combination of mechanical parts and computer coding. 
 - It was a mechanical analog computer that could predict the ebb of tides and even the height of tides that could be irregular. 
 - It was widely used for marine networks and navigation. Later on many improvisations and additional features were added on it. 
 - During the world war times, this tide prediction machine was of great use for military purpose.

Answer:
20 Ω
Explanation:
Voltage, current, and resistance are related by Ohm's law:
V = IR
40 V = (4 A) R
R = 10 Ω
The total resistance of the circuit is 10 Ω.
Resistors in parallel have a total resistance of:
1/R = 1/R₁ + 1/R₂
1 / (10 Ω) = 1 / (20 Ω) + 1/R₂
R₂ = 20 Ω
