How large does the Moon appear in the sky? - half a degree How large is the Big Dipper - more than 20 degrees The 2 Stars Alcor and Mizar are easily seperated by the human eye. This means they must be father apart than.. - one arc minute What is seeing? - The diameter of the blur caused by the atmosphere Which of the following limits the magnification of all but the smallest telescopes? - seeing What is an 8 x 50 pair of binoculars? - Magnification = 8 x, diameter = 50 mm How small is the...

Tangent intersects a circle in only 1 place. Secant intersects a circle in 2 places. Intersection of a tangent and a radius form right angles when they intersect. Equation of a circle x minus h squared plus y minus k squared equals radius squared. Circumference of a circle 2 times pi times radius or pi times diameter. Area of a circle pi times radius squared. Central angle is equal to its intercepted arc. Inscribed angle is equal to ½ its intercepted...

Welding Fundamentals - Chapter 15: GMAW and FCAW Latest Update Graded A+ How does the wire feed speed influence the quality of a GMAW weld? Wire feed speed affects the arc length and heat input; an optimal feed speed ensures a stable arc and proper fusion, while too fast or too slow can lead to defects such as burn-through or lack of penetration. Why is the choice of gas important in GMAW? The choice of gas is important because it affects the arc stability, penetration, and overall...

114 MiG Final Exam Questions and Answers 100% Pass What is the primary difference between MIG and TIG welding? MIG welding uses a continuously fed wire as an electrode, while TIG welding uses a non- consumable tungsten electrode. How does the choice of shielding gas impact the appearance of the weld? Different shielding gases can affect the color, bead shape, and overall quality of the weld. What does the term "travel speed" refer to in MIG welding? Travel speed refers to...

Combustible Liquid - Correct answer-A liquid with a flash point ABOVE 100F 12.5 - Correct answer-If the current flowing out from an electrical panel is 12.5 amps, and it then flows through an electrical load of 1500 watts, what is the amperage of the remaining current flow of the return circuit? 1000 - Correct answer-If a hair dryer draws 8.3amps (in a home with 120-volt service), what is the wattage? *Power (P) = current (I) x voltage (V) Watts = amps x volts 1987 - Correct answer-The y...

FCAW Chapter 13 & 14 Vocab with Complete Solutions What is meant by the term "arc length" in FCAW? Arc length refers to the distance between the welding wire and the workpiece; maintaining the correct arc length is crucial for achieving a stable arc and quality welds. What does the term "heat-affected zone" (HAZ) refer to in welding? The heat-affected zone (HAZ) is the area of the base metal that has been altered by the heat of the welding process, potentially affecting ...
