Answer:
D) quantity of components required for this type of system
Explanation:
Electricity can be transmitted using the alternating and direct currents. The alternating current is one in which the flow of the current diverts at certain time intervals whereas, the direct current is one in which there is a constant one-directional flow of current. The DC is used in batteries and solar panels. Residential areas and business places make use of the AC current.
One of the several reasons why the DC is not used in homes is because unlike the AC it is not easy to build and sustain. Moreso, it has more components compared to the AC. For example, its motor consists of brushes and commutators . The components, example, switches are also large compared to the AC components.
Answer:
D. Overrule any other laws and traffic control devices.
Explanation:
Laws and traffic control devices are undoubtedly compulsory to be followed at every point in time to control traffic and other related situations. However, there are cases when certain instructions overrule these laws and traffic control devices. For example, when a traffic police is giving instructions, and though the traffic control devices too (such as traffic lights) are displaying their own preset lights to control some traffic, the instructions from the traffic police take more priority. This is because at that point in time, the instructions from the traffic control devices might not be just applicable or sufficient.
Also, in the case of instructions given by construction flaggers, these instructions have priority over those from controlling devices. This is because during construction traffic controls are redirected from the norms. Therefore, the flaggers such be given more importance.
Answer:
V₅ = 20 V
Explanation:
Given that
Total voltage ,V= 120 V
Given that resistor are connected in series that is why the total voltage drop will be summation of voltage drop in the all resistor.
V₁=Voltage drop on first resistor
V₂=Voltage drop on second resistor
V₃=Voltage drop on third resistor
V₄=Voltage drop on forth resistor
V₅=Voltage drop on fifth resistor
Therefore
V= V₁+V₂+V₃+V₄+V₅
120 = 35 + 28 + 22 + 15 + V₅
V₅ = 20 V
Therefore the voltage drop on the fifth resistor will be 20 V.
The statement about (12+x) that is true is that A.The expression (12+x) is a factor that represents the total number of pillows the artisan makes on Monday and Tuesday.
<h3>What is an expression?</h3>
An expression is simply used to show the relationship between the numbers or variables illustrated.
In this case, the artisan makes a batch of pillows on Monday and makes x more pillows on Tuesday to sell at the convention.
Here, (12 + x) is a common factor that illustrates the number relating to the pillows.
Therefore, the correct option is A.
