AC (Alternating Current) generator is a device that produces an electromotive force.This generator produces alternating current. Alternating current is electric current that changes its direction many times a second, at regular intervals. This is the type of current with which customers are supplied in the energy distribution network.
A ph higher than 7 is basic so you can eliminate a. The indicator can be used to measure both acids and bases so you can eliminate c. Hydrogen ions are from acids, so the answer is that the powder decreased the hydrogen ions in the water.
Answer:
The mass of the rule is 56.41 g
Explanation:
Given;
mass of the object suspended at zero mark, m₁ = 200 g
pivot of the uniform meter rule = 22 cm
Total length of meter rule = 100 cm
0 22cm 100cm
-------------------------Δ------------------------------------
↓ ↓
200g m₂
Apply principle of moment
(200 g)(22 cm - 0) = m₂(100 cm - 22 cm)
(200 g)(22 cm) = m₂(78 cm)
m₂ = (200 g)(22 cm) / (78 cm)
m₂ = 56.41 g
Therefore, the mass of the rule is 56.41 g
B. truthfully it's the only one that makes sense
A Cone of Depression occurs when a well pumps water from a certain area and causes a depression in a cone shape in the water table.
