Answer:
More accidents occur at intersections than anywhere else. One of the reasons for this is because most of the intersections have stop signs. Because there are more accidents at intersections with stop signs than those with signals or roundabouts, stop signs are not as effective in preventing accidents. This is probably why the number of accidents at Walnut and Birch Streets is so high.
Explanation:
Answer: 76.3 ° C
Explanation:
Outside Distance = 10 m
Outside diameter, d = 2.2 m
R=D/2 = 2.2/2= 1.1 m
inner radius, Rs = = 1.1 m
Surface Temperature Ts = 20°C
Given that the thermal conductivity of soil, K = 0.52 W/mK
We can find the outside temperature of the container by finding the thermal temperature of conductor, T, and then summing up with the surface temperature
That is (T + Ts)
we know amount of heat, Q is given by :
Q = [(T-Ts) / (R- Rs)/4πKRRs
500 = T-20 [4π×0.52×1.1×10] / (10-1.1)
500= T-20 (71.88/8.9)
500 = T-20 (8.08)
500 = 8.08T - 161.6
8.08T = 500 + 161.6
8.08T = 661.6
T = 76.33 ° C
