Burning jet fuel is not hot enough to fully melt steel. Burning jet fuel, however, is more than hot enough to weaken steel.
Answer:
Explanation:
Given
mass flow rate=0.3 kg/s
diameter of pipe=5 cm
length of pipe=10 m
Inside temperature=22
Pipe surface =100
Temperature drop=30
specific heat of vapor(c)=2190 J/kg.k
heat supplied 
Heat due to convection =hA(100-30)




19,710=122.538 h

Answer:
c. 716, 800 J
Explanation:
t = Time taken
u = Initial velocity = 32 m/s
v = Final velocity = 0
s = Displacement = 60 m
a = Acceleration
m = Mass of car = 1400 kg

Work done is given by

The amount of work done to stop the car is 716800 J
<span>All matter can exhibit wave-like behavior, but the question asks if it is significant. A bullet is a very, very large object compared to the light wave-particles where the wave nature is typically observed. So for an object of this magnitude, it is insignificant.</span>
