Answer:
The percentage of the remaining alloy would become solid is 20%
Explanation:
Melting point of Cu = 1085°C
Melting point of Ni = 1455°C
At 1200°C, there is a 30% liquid and 70% solid, the weight percentage of Ni in alloy is the same that percentage of solid, then, that weight percentage is 70%.
The Ni-Cu alloy with 60% Ni and 40% Cu, and if we have the temperature of alloy > temperature of Ni > temperature of Cu, we have the follow:
60% Ni (liquid) and 40% Cu (liquid) at temperature of alloy
At solid phase with a temperature of alloy and 50% solid Cu and 50% liquid Ni, we have the follow:
40% Cu + 10% Ni in liquid phase and 50% of Ni is in solid phase.
The percentage of remaining alloy in solid is equal to
Solid = (10/50) * 100 = 20%

Explanation:
I can tell you rn, without doing the math, that ur chances are very slim. That almost never works. I took a math quiz like that once, it had 12 questions and I made a 5%...that 5/100.

Answer:
The dept of the water needed is 26.11m
Explanation:
Given the following parameters:
Length of the pipe = 
Diameter of the pipe = 
Volumetric flow rate 
Knowing that:
Volumetric flowrate 
==> 
*Knowing that 
==> 
==> 
Hence, the dept of water needed to produce a volumetric flow rate of is 26.11m.
Answer:
Explanation:
outside air must be mixed with return air at some point in time because here is an example a warm current of air comes in contact with a cold current of air the warm current has to cool down so it could mix with the cold current or if they don´t mix they would continue to bump into each other and probably cause a tornado. probably.
