Answer:
R = ½ R₀
Explanation:
This is an exercise in Ohm's law,
V = IR
in the initial case
V₀ = I₀ R₀ (1)
indicates that the voltage remains constant and the current is doubled
I = 2 I₀
V₀ = I R
we substitute
V₀ = 2 I₀ R
R = ½ V₀ / I₀
we replace by equation 1
R = ½ R₀
Answer: The answer position may vary. But the correct answer is D. No; Raul changes more than one variable so the results will be invalid.
Explanation:
Raul's experimental set-up will not produce valid results because he intends to change more than one variable.
One variable that Raul will change is the pot size. According to the description, however, Raul will also change one other variable—the type of flower that is planted. Even though Raul plans on using flowers only, he should use the same type of flower in each pot, not different types.
Valid results are only produced when only one variable is changed at a time.
None of them are the correct answers.
