Answer:
Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them. ... Electricity is the flow of electrons or ions. For electrolysis to work, the compound must contain ions.
Answer:
The first answer is W and Z, since they appear to be a period apart. Dont know the second question. I did what I could, hope someone can answer the second.
Answer:
increased by 9 times
Explanation:
As the period of a simple pendulum is defined as the following formula
where L is the length of the pendulum and g is the constant gravitational acceleration. Since L is under a square root, if you want to triple the period of vibration, L must be increased by 9 times so that 
Answer:
2.88×10⁻⁹ s
2.40×10¹⁵ m/s²
Explanation:
Given:
v₀ = 12300 m/s
v = 6.92×10⁶ m/s
Δx = 0.997 cm = 0.00997 m
Part 1) Find: t
Δx = ½ (v + v₀)t
0.00997 m = ½ (6.92×10⁶ m/s + 12300 m/s) t
t = 2.88×10⁻⁹ s
Part 2) Find: a
(6.92×10⁶ m/s)² = (12300 m/s)² + 2a (0.00997 m)
a = 2.40×10¹⁵ m/s²
