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: B Excretory
Explanation: Hope this helps :)
Answer:
The rate of energy absorbed per unit time is 3500W.
Explanation:
From the question, we were given the following parameters;
Plane, opaque, gray, diffuse surface
â = 0.7
Surface area, A = 0.5m²
Incoming radiant energy, G = 10000w/m²
T = 500°C
Rate of energy absorbed is âAG;
âAG = 0.7 × 0.5 × 10000
âAG = 3500W.
The energy absorbed is measured in watts and denoted by the symbol W.
Answer:
0.75 in
Explanation:
The 1 inch measure has 16 divisions.
Find the measure of 1 division as: 1/16 = 0.0625 in
The side length of the square has 12 divisions
1 division = 0.0625 in
12 divisions = 0.0625*12 = 0.75 in
The correct answer choice is A. 0.75.
Answer choices B is incorrect because from the diagram, it is clear that the side length of this square is less that 1 inch.
Answer choice C is incorrect because 0.34 in will mean 0.34/0.0625 divisions. This is 5 divisions, yet the square side length covers 12 divisions.
