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:
initial diameter of the sample is 2.95 mm
Explanation:
given data
yield load = 2100 N
maximum load = 3400 N
failure load = 2350 N
ultimate engineering stress = 497.4 MPa = 497 ×
N/m²
to find out
What was the initial diameter of the sample in mm
solution
we will apply here ultimate engineering stress formula that is express as
ultimate engineering stress =
...............1
here A is area and P max is maximum load applied
so area =
here d is initial diameter
so put all value in equation 1
497 ×
= 
solve it we get d
d = 2.95 ×
m
so initial diameter of the sample is 2.95 mm
