A) You'll notice from "c)" that the distance the object travelled was 75m, so you get V_a_v_e_r_a_g_e = 75m/15s = 5 m/s.

b) a = dV/dT, so a = (0-10)/15 and then you get a = -2/3 m/s ^{2}.

c) S = S_0 + V_0T + 0,5aT^2 and you get S = 10T - (2/6)T^2 and you plug in T = 15s and you'll get S = 75m

What is the change in length of a 1400. m steel, (12x10^-6)/(C0) , pipe for a temperature change of 250.0 degrees Celsius? Remem
8090 [49]

Answer:

\Delta L = 4.2 m

Explanation:

As per the formula of thermal expansion we know that

L = L_o(1 + \alpha\Delta T)

so here we will have

L_o = 1400 m

\alpha = 12 \times 10^{-6} per ^oC

\Delta T = 250 degree C

so here change in the length of the rod is given as

\Delta L = L - L_o

\Delta L = L_o \alpha \Delta T

\Delta L = 1400 (12 \times 10^{-6})(250)

\Delta L = 4.2 m
