Answer:
They are not conductors of heat.
Explanation:
Metals, like steel, are good conductors because of the particles they are made of. Materials like rubber are good insulators, because they don't pick up heat easily. Vacuums(not vacuum cleaners, matter-less voids) are good insulators.
Answer:
5. 7.452 min
Explanation:
Momentum is conserved, so:
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
0 = (0.695 kg) (-12 m/s) + (59 kg) v
v = 0.1414 m/s
She is 63.2 m away, so the time it takes to reach the shuttle is:
t = 63.2 m / 0.1414 m/s
t = 447.1 s
t = 7.452 min
<span>Carnot cycle efficiency = work done/heat supplied = (Th - Tc)/Th
where, Th is temperature of hot reservoir and Tc is temperature of cold reservoir.
we have given the values as Heat supplied = 1.3 MJ or 1300 KJ, Th = 427 degree C and Tc = 90 degree C.
converting degree Celsius to kelvin temperatures, Th = 427 + 273 = 700 K
Tc = 90 +273 = 363
solving equations, (700 - 363)/700 = work done / 1300
work done = 625.86 KJ i.e. 0.626 MJ work is done .</span>
