•corded
•cable technology
•none of these
Answer:
Wireless
Explanation:
A wireless remote control can be an advantage to an operator who is welding close to the power source. Hence, option A is correct.
What is wireless remote control?An electrical device used to wirelessly and remotely operate another device is a remote control, often known as a remote or clicker. Consumer gadgets, such as television sets, DVD players, and other home appliances, can be controlled by a remote control.
In the current electronic market, remote control systems fall into three primary categories: IR-based systems, RD-based systems, and BT-based systems. the receiver and the remote must be lined up exactly for infrared, also known as IR.
IR, on the other hand, is unable to pass through a number of materials but can operate over a much wider spectrum. This allows the user far greater freedom and control in environments with challenging terrain and obstacles.
Thus, option A is correct.

In manufacturing a particular set of motor shafts, only shaft diameters of between 38.20 and 37.50 mm are usable. If the process mean is found to be 37.80 mm with a standard deviation of 0.20 mm, what percentage of the population of manufactured shafts are usable?
Answer:
we can conclude that 91.04% population of shafts are usable
Explanation:
Given that;
X[tex]_{min}[/tex] = 37.50 mm
X[tex]_{max}[/tex] = 38.20 mm
mean μ = 37.80
standard deviation σ = 0.20 mm
This problem is based on normal probability distribution so, to get the probability, we must calculate; z = x-μ / σ
so;
Z[tex]_{min}[/tex] = (X[tex]_{min}[/tex] - μ) / μ = (37.50 - 37.80) / 0.20 = -1.5
Z[tex]_{max}[/tex] = (X[tex]_{max}[/tex] - μ) / μ = (38.20 - 37.80) / 0.20 = 2
Hence;
P( 37.50 < X < 38.20 ) = P( -1.5 < Z < 2 )
P( 37.50 < X < 38.20 ) = P( 0 < Z < 1.5 ) + P( 0 < Z < 2 )
from the standard normal table table;
P( 37.50 < X < 38.20 ) = 0.4332 + 0.4772
P( 37.50 < X < 38.20 ) = 0.9104 = 91.40%
Hence, we can conclude that 91.04% population of shafts are usable

Recourses needs to provide goods or services are called?
Answer:
Resources needed to provide goods or services are called factors of production
Explanation:
Further Explanation:
Factors of reproduction
Factors of reproduction are inputs or resources that are used in the generation of goods and services with an aim of making profit.
There are four main factors of production which include;
Land
Labor
Capital
Entrepreneurship
Land
This refers to all the natural resources that are available to be used in the production of goods.
These natural resources includes raw materials from the ground, non-renewable resources such as petroleum and renewable resources such as timber.
The income or reward earned from land as a factor of production is rent.
Labor
This refers to the manpower or work done by human beings.
The value of labor depends on the skills, education and motivation of workers.
The reward for labor as a factor of production is wages and salaries.
Capital
This refers to the capital goods, that is, man-made objects that are used for production of goods and services such as machinery, equipment and chemicals.
They also include industries and commercial buildings.
The reward or income earned from capital goods is interest
Entrepreneurship
It involves coming up with an idea and developing it into profitable business.
An entrepreneur is therefore an individual who combines the other factors of production to build a business and add the supply in the economy.
The reward or income earned by entrepreneurs is profit.

Explanation:
The in-situ dry density of a sand is 1.72Mg/m3. The maximum and minimum drydensities, determined by standard laboratory tests, are 1.81 and 1.54 Mg/m3,respectively. Determine the relative density of the sand and soil description based on its density.
Answer:
Relative density = 0.7 or 70%
Explanation:
The following information was provided by this question
Pd = 1.72mg/mg³
Pd max = 1.81 mg/mg³
Pd min = 1.54 mg/mg³
We substitute into the formula. This formula is contained in the attachment.
[(1/1.54)-(1/1.72)]/[1/1.54 - 1/1.81]
= 0.649350 - 0.581395 / 0.649350 - 0.552486
= 0.067955/0.096864
= 0.7015
= 0.7
The relative density is Therefore 0.7 or 70% when converted to percentage

The basic dc-dc converter of Fig. 6-2a has a source of 100 V and a load resistance of 10 ⦠The duty ratio of the switch is D = 0.6, and the switching frequency is 1 kHz. Determine (a) the average voltage across the load, (b) the rms voltage across the load, and (c) the average power absorbed by the load. (d) What would happen if the switching frequency were increased to 2 kHz?
Answer:
a. 60V
b. 77.46V
c. 600 W
d. there would be no effect when this is done
Explanation:
a.
to get value of average output
Vo = VsD
Vs = 100V
D = 0.6
Vo = 100 V * 0.6
Vo = 60V
Therefore 60V is the value of average voltage
b.
The rms voltage:
= Vs√D
= 100 x √0.6
= 100 x 0.7746
= 77.46V
the rms voltage is Therefore 77.46V
c.
value of average power:
= (RMS)²/R
R = 10
when we put into formula above,
= (77.46)²/10
= 6000.05/10
= 600.005 W
= 600W
d.
If switching frequency is changes to be 2khz it would actually have no effect on the average voltage, average power or rms voltage.
