    Undergrad Pressure problem(Fluid mechanic)

    1. Homework Statement enclosed, thanks for checking 2. Homework Equations P = ρgh 3. The Attempt at a Solution I have try to add up all pressure in the tank (including gauge pressure, pressure of the oil(ρg*0.5), pressure of the water(ρg*0.8)) but still can't balance out the...

    Resistance problem (Simple electrical problem)

    I finally find out the way to solve this question first find out R0 which is the resistance at 0°C 10 = R0 (1+0.00393*(10-0)) then I can use the equation to solve the rest of the problem and figure out R80 R80= R0 (1+0.00393*(80-0)) I guess i was stuck on some logic problem glad i can...

    Resistance problem (Simple electrical problem)

    Homework Statement This question comes from one of my previous exam and I still couldn't solve it after days of trying hope someone can guide me through this thanks A copper wire has a resistance of 10Ω at 10°C. Determine the resistance of the wire at 80°C. Given that the temperature...
