Answer:
Two 50 Ohm Resistors, One 20 Ohm Resistor.
Explanation:
For the given current and voltage specifications, the resistance can be calculated by Ohm's Law:
where,
R = Resistance = ?
V = Voltage = (1.5 V)(4) = 6 V
I = 0.05 A
Therefore,
Now, to minimize the cost we will buy the following set of resistors:
<u>Two 50 Ohm Resistors, One 20 Ohm Resistor.</u>
Answer:
D. The circulatory system transports oxygen that the respiratory system brings into the body.
Explanation:
the first two answers either refer to carbon dioxide as beneficial and necessary to the body(it sometimes is but not in this case)
the answer choice c refers to oxygen being transferred directly to the heart. This is also incorrect.
the only proper answer to this question is answer choice d.
