An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
In the given DoD acquisition scenario, the evaluation of the bids is based on a tradeoff between price and past performance. The possible awardee should be selected by considering both the quoted price and the past performance ratings of the vendors.
Let's analyze the options provided:
Vendor A : This vendor has a past performance rating of 'Unacceptable' and quoted a price of $216,150. Generally, a bid with an 'Unacceptable' past performance rating would not be considered for an award regardless of price. Thus, Vendor A is not likely to be awarded the contract.
Vendor B : This vendor has a past performance rating of 'Acceptable' with a quoted price of $248,500. Although more expensive than Vendor C, Vendor B has an acceptable past performance rating.
Vendor C : This vendor has a past performance rating of 'Outstanding' and quoted a price of $237,200, which is lower than Vendor B's price. Vendor C not only has better past performance but also offers a more competitive price compared to Vendor B.
Given the tradeoff between price and past performance, Vendor C is likely the most favorable choice as they offer a strong past performance rating coupled with a competitive price. Thus, they would be the apparent awardee based on the stated criteria.
Therefore, the correct statement about the award decision is:
Vendor C is the apparent awardee and price reasonableness would be based on competition.
In 30 seconds, an electric device with a current of 15.0 A delivers approximately 450.0 C of charge. This amount of charge corresponds to around 2.81 x 10^21 electrons flowing through the device. The calculation involves using the charge-current-time relationship and the charge of a single electron.
