Answer:
While the use of the type of transformer in a rectifier depends on the voltage requirement or to meet desired operating conditions, a step-down transformer is used mainly to reduce the voltage. It is used to bring the high AC voltage level to a reasonable value or the desired output voltage.

Correct me if Im wrong
Given: Heat Qout means useful work = 2800 J
Heat Qin = 8900 J
Required; Efficiency = ?
Formula: Efficiency = Qout/Qin = x 100%
= 2800 J/8900 J = 0.3146 X 100 %
Efficiency = 31.46%
Pressure = (total force) / (Area)
10,000 Pa = (1,000 N) / (Area)
Multiply each side by (Area) :
(10,000 Pa) x (Area) = 1,000 N
Divide each side by (10,000 Pa) :
Area = (1,000 N) / (10,000 Pa)
<em>Area = 0.1 m² </em>
<span>The scales is 1 m = 10 dm = 100 cm = 1000 mm. Then 10 dm equals 1000 mm and 1 dm equals 100 mm.The names of the measures in that scale are meter, decimeter, centimeter and milimiter. So, the answer is that the length that is 100 times larger than a milimieter is the decimeter (dm). </span>
The answer to this questions would be nuclear engineer. The overall career of engineering would require physics as engineers need to know how the overall mechanics of nature affect the way their structure is built.
Hope this helped :D
