Asquare steel bar of side length w = 0.18 m has a thermal conductivity of k = 15.3 j/(s⋅m⋅°c) and is l = 1.7 m long. once end is placed near a blowtorch so that the temperature is t1 = 81° c while the other end rests on a block of ice so that the temperature is a constant t2.
input an expression for the heat transferred to the cold end of the bar as a function of time, using a = w2 as the cross-sectional area of the bar. sig. gif? tid=2g65-6a-d8-4e-a33a-19217
how much energy, in joules, was conducted in 1 hour, assuming t2 = 0° c?
input an expression for the mass of the water melted in 1 hour using q1 from above and lf the latent heat of fusion. sig. gif? tid=2g65-6a-d8-4e-a33a-19217

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?
