Subtract the value of the second pair from the value of the first pair, or 18 - 8 = 10. Our determinant equals 10. Once again, determine the sign dictated by the location of the element you eliminated. In this case, the sign is +, so we would use 10. Next, let's find the cofactor of 5.
Answer: The outermost zone of a flame is the hottest zone. Due to this, goldsmith uses the outermost zone of a flame for melting gold and silver. Question: 11. In an experiment 4.5 kg of a fuel was completely burnt.
The third section, the reflow zone, is also referred to as the âtime above reflowâ or âtime above liquidusâ (TAL), and is the part of the process where the maximum temperature is reached. An important consideration is peak temperature, which is the maximum allowable temperature of the entire process.he rampâup rate is usually somewhere between 1.0 Â°C and 3.0 Â°C per second, often falling between 2.0 Â°C and 3.0 Â°C (4 Â°F to 5 Â°F) per second. If the rate exceeds the maximum slope, damage to components from thermal shock or cracking can occur.
