Answer:
18 kJ
Explanation:
Given:
Initial volume of air = 0.05 m³
Initial pressure = 60 kPa
Final volume = 0.2 m³
Final pressure = 180 kPa
Now,
the Work done by air will be calculated as:
Work Done = Average pressure × Change in volume
thus,
Average pressure = 
= 120 kPa
and,
Change in volume = Final volume - Initial Volume = 0.2 - 0.05 = 0.15 m³
Therefore,
the work done = 120 × 0.15 = 18 kJ

Answer:
Their feathers are light and the shape of their wings is perfect for catching the air. Their lungs are great at getting oxygen and very efficient, so they can fly for very long distances without getting tired. They eat lots of high-energy food.
Answer:
So 1/Rt=1/4+1/4+1/2=4/4 = 1 so Rtotal=1
Answer:
Decrease
Explanation:
Generally with increasing the temperature the mechanical properties of material decreases.But some materials have exceptions like tempered steel because when temperature increase then young modulus of elasticity of tempered steel increases.
So we can say that when with increasing temperature the properties of materials Yield and tensile strengths and modulus of elasticity decreases.
Decrease
