Question 3:
(a) (6 points) We place 120.0 g of a metal at 80.00oC in
436.3 g of water at 25.00oC. The water is in a beaker
that is also at 25.00oC. The specific heat of water is
4.184 J K-1 g-1 and the heat capacity of the
beaker is 0.6666 kJ K-1. The specific heat capacity of
the metal is 0.4444 J K-1 mol-1. What is the
final temperature of the metal, the water, and the beaker?

Problem 2. A long thin alloy wire with a diameter of 0.2 mm is exposed to ambient air at T, -25°C with a combined heat transfer coefficient h-10 W/m2.K (due to natural convection and radiation). An electric current10.15 A flows through the wire. The electrical resistance of the wire per unit length is R-162/m. (a) Draw a control volume to write down the energy balance equation. (b) Determine the steady-state temperature of the alloy wire, assuming that the solid wire...

I need help answering 7 and 8. Thanks!
A transverse travelling wave on a taut wire has an amplitude of 0.200 mm and a frequency of 600 Hz. It travels with a speed of 196 m/s. If the wave equation is written in the form y = A sin(kx- ohm t), what are the parameters A, K, and ohm? M rad/m rad/s The mass per unit length of this wire is 3.50 g/m. Find the tension in the wire.

Need help with part B (the sketching!) thanks
Problem 3: A thin flat plate of length L-120 mm, thickness t=4 mm, width W=30 mm, and thermal conductivity k=20 W/m-K is thermally joined to heat sinks at different temperatures, where T(x = 0) = To-100 C and T(x = L) = T,-35°C. The top surface of the plate is subjected to uniform heat flux q"-20 kW/m2, and the bottom surface of the plate is subjected to uniform convection with a convection...

Figure < 1 of 1 Consider, for instance, a bar of initial length L and cross-sectional area A stressed by a force of magnitude F. As a result, the bar stretches by AL (Figure 1) Let us define two new terms: • Tensile stress is the ratio of the stretching force to the cross-sectional area: stress = 5 • Tensile strain is the ratio of the elongation of the rod to the initial length of the bar strain= 41 It...
