Answer:
a) i₈ = 0.5 i₄, b) i₁₀ = 0.3 i₃, i₁₀ = 0.8 i₈
Explanation:
For this exercise we use ohm's law
V = i R
i = V / R
we assume that the applied voltage is the same in all cases
let's find the current for each resistance
R = 4 Ω
i₄ = V / 4
R = 8 Ω
i₈ = V / 8
we look for the relationship between these two currents
i₈ /i₄ = 4/8 = ½
i₈ = 0.5 i₄
R = 3 Ω
i₃ = V3
R = 10 Ω
i₁₀ = V / 10
we look for relationships
i₁₀ / 1₃ = 3/10
i₁₀ = 0.3 i₃
i₁₀ / 1₈ = 8/10
i₁₀ = 0.8 i₈
Its about the same amount of weight being pushed on both sides so its evened out
Each pure element has certain chemical properties, a specific atomic arrangement and a specific crystalline structure that distinguish this pure element from other elements.
On the other hand, the mass of any substance/object depends on the AMOUNT or the QUANTITY of matter in the object.
Based on the above, three objects made of pure iron would have:
Different masses
Same arrangement of atoms
Same crystal structure
Same chemical properties
Comparing the above to the given choices, we would find that the best choice is:
b. They have the same chemical properties
Answer:
The answer is A. A transistor
