Answer:
Tack coat is a sprayed application of an asphalt binder upon an existing asphalt or Portland cement concrete pavement prior to an overlay, or between layers of new asphalt concrete.
Explanation:
Answer:
Shelf life.
Explanation:
In Business, an inventory is a term used to describe a list of finished goods, goods still in the production line and raw materials that would be used for the manufacturing of more goods in a bid to meet the unending consumer demands.
Simply stated, an inventory can be classified into three (3) main categories; finished goods, work in progress, and raw materials.
An inventory is recorded as a current asset on the balance sheet because it's primarily the most important source of revenue for a business entity.
Also, the three (3) main cost concept associated with an inventory are;
1. First In First Out (FIFO).
2. Last In First Out (LIFO).
3. Weighted average cost.
Shelf life can be defined as a measure of the length of time that a particular product could be kept or stored without it getting bad or becoming unsuitable for use by the consumers. Thus, the shelf life of a product is largely dependent on its expiration date.
Hence, merchandise without an expiration date like electronics, tools and home goods typically have a longer shelf life.
Answer:
R= 53.7 Ω
Explanation:
fc= 1/(2πRC)
3000=1/(2π× 1 × 10^-6 × R)
R= 53.7 Ω
Answer:
Buffers in electrical systems are amplifiers that prevent input voltage from being affected by whatever curent the load draws
Explanation:
The input and output parts of the circuit are isolated. By having high-impedance(following ohms law, V=IR) very small current is drawn by the amplifier circuit. The output and input voltages are same. However, the output impedance is very low. In this way power losses are minimized and vlotage levels are maintained for the load
They are useful where a measurement of small signal is required in the presence of high voltage.
They are also used in multi-stage filters to isolate one stage from another
