)(si units) a shielded metal arc-welding operation is performed on low-carbon steel plates at a voltage = 25 volts and current = 150 amps. the heat transfer factor = 0.90, and the melting factor = 0.75. the melting temperature of low-carbon steel = 1487°c, and the unit melting energy can be determined by the methods of the previous chapter. using si units, determine the (a) rate of heat generation at the weld and (b) volume rate of metal welded.

From the perspective of an employee that effective channeling of work related information and concerns

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.

Refer to your lab guide and review the data in table b to complete each statement. the mass of g1 + g2 after the collision kg. the velocity of g1 + g2 after the collision m/s. the momentum of the combined gliders after the collision kg · m/s.
