F. HC2H3O2
G. HCIO
H. H2SO4
Answer:
Explanation:
Given that,
Small wheel applied force
F₁ = 50N
Small wheel radius
r₁ = 18cm
Bigger wheel radius.
r₂ = 29cm
Bigger wheel applied force
F₂ =?
Since the combination of those forces did not cause the wheel to rotate,
Then, Στ = 0
F₁•r₁ —F₂•r₂ =
50×18 — 29F₂ = 0
900 = 29F₂
F₂ = 900 / 29
F₂ = 31.03 N
The pulling force applied at the larger wheel is 31.03N
Answer:
Eating food produce locally makes it where big trucks don't have to bring it to the restaurant
Explanation:
When the big trucks drive it they release pollutants into the air so therefore when you get stuff produced locally you don't have the big trucks polluting the air. So therefore it is better for the environment.
Ohm’s Law states that electrical current is proportional to voltage and therefore inversely proportional to resistance - V = I x R
