Calculate the number of turns needed in the secondary winding of a transformer to transform a primary voltage of 300 volts down to a secondary voltage of 180 volts, if the primary winding has 1150 turns of wire. N secondary = Question 4

This shadow clock or sundial permitted one to measure the passage of hours within a day. Another very early form of clock to tell the time was the water clock. The water clock was used by the ancient Greeks. What was used to measure time in the olden days? sundial The Egyptians used the sundial to measure time, and so did the Greeks and the Romans.

What is soil fertility? Soil fertility is the ability of a soil to sustain plant growth by providing essential plant nutrients and favorable chemical, physical, and biological characteristics as a habitat for plant growth. Plant nutrients include the macronutrients nitrogen, phosphorus and potassium, sulfur, calcium and magnesium.

Best Answer. Copy. Lactometer is used t measure the purity of milk. Lactometer is an instrument invented by Mr. Dicas, of Liverpool, for the purpose of ascertaining the different qualities of milk.

The 8-inch gauge used in the National Weather Service is of a standardized design used throughout the world for official rainfall measurements. This standardization provides uniformity, continuity, and credibility of precipitation data worldwide. There are two basic type of the 8-inch gauge: a large capacity gauge and a small capacity gauge.

3. Area Height Method Width is calculated from the peak area and height values. This method provides relatively accurate and reproducible widths, even for distorted peaks, but results in somewhat larger N values when peak overlap is significant. ・・・3) A: Area, H: Height 4. EMG Method (Exponentially Modified Gaussian)

The diameter of a cylinder is measured using a vernier callipers with no zero error. It is found that the zero of the vernier scale lies between \( 5.10 \mat.

A student measured the diameter of a small steel ball using a is \( 5 \mathrm{~mm} \) and zero of circular scale division coincides with 25 divisions above t.

Time interval is the duration or elapsed time between two events. The standard unit of time intervalis the second(s). However, many engineering applications require the measurement of shorter timeintervals, such as milliseconds (1 ms = -3-6-910 s), microseconds (1 µs = 10 s), nanoseconds (1 ns = 10 s), and picoseconds (1 ps = 1012 s).

On a screw micrometer, for 0.5 mm it equals 5 + 0.5 = 5.5 mm. Where 1 strip represents 0.5 mm. But this only applies after passing 5 strips or lines above. When you have crossed the 5 line limit and start to enter the 6th strip, the reading method is different again. The total distance can be read as (5 + 6) x 0.5 mm = 5.5 mm.

FAST.com provides two different latency measurements for your Internet connection: “unloaded” and “loaded” with traffic. The difference between these two measurements is also called “bufferbloat”.
