In a polytropic process, with the exponent n = k, where k is the specific heat ratio, 1.0 kg of neon (an ideal gas) in a frictio

n-free piston-cylinder assembly expands from 400 k and 500 kpa to 100 kpa. for neon, ne = 20.18 kg/kmol and k = 5/3. sketch the system and the process. previously, you should have evaluated the work done by the gas in this process = _________ kj now find the final temperature of the gas (using the polytropic formulas for ideal gases), and then find the change in internal energy for the process = ___________ kj

George and Harriot walk with an average velocity of .95 m/s eastward. If it takes them 30
artcher [175]

Answer:

1.71 km

Explanation:

Convert 30 minutes to seconds:

30 min × (60 s / min) = 1800 s

Find the displacement:

0.95 m/s × 1800 s = 1710 m

Convert to kilometers:

1710 m × (1 km / 1000 m) = 1.71 km

Density: Two blocks, A and B, are put in a tank of water. Block A has a density of 1.21 g/cm³. Block B has a density of 1.37 g/c
stira [4]

Answer:

Block A

Explanation:

Block A will float higher in the water compared to the second Block.

The density of water is 1g/cm³.

According to the principle of floatation "an object that floats in a liquid will displace equal amount of fluid to the weight of the object".

A body will become more submerged in water if it has more density because density is the mass per volume of  body.

An object with a higher density than another will sink in the liquid of the one with lesser density.

  • Object A has lesser density and will float higher up and displace very little water.
  • Object B has higher density and will be more submerged.
